- `Ccnp Certification / Bcmsn Exam Tutorial: Hsrp Mac Addresses And Timers By : Chris Bryant, CCIE #12933
To earn your CCNP certification and pass the BCMSN exam, you've got to know what HSRP does and the many configurable options. While the operation of HSRP is quite simple (and covered in a previous tutorial), you also need to know how HSRP arrives at the MAC address for the virtual router - as well as how to configure a new MAC for this virtual router. This puts us in the unusual position of creating a physical address for a router that doesn't exist!
The output of show standby for a two-router HSRP configuration is shown below. - Yahoo And The Peanut Butter Manifesto By : Chris Bryant, CCIE #12933
One of the great internal battles at any successful company is the desire to expand versus the desire to branch out into other areas. After all, if an organization is wildly successful at one thing, they usually feel that they can be successful at anything.
That line of thinking is particularly true at Yahoo, Google, and MSN, today's three largest search engines. All three companies are continually expanding, and a senior executive at Yahoo recently sent an internal memo that basically said Yahoo is spreading itself too thin. Nothing unusual there, since it's common for executives at rapidly-expanding companies to guard against such things - but the comparison the exec used to draw this conclusion was rather unusual. - Why Taking A Computing Course Is A Good Idea By : Morgan Hamilton
It would be a wise idea to take advantage of a contemporary computing course because knowing how to operate a computer is one of those imperatives in life these days. I’m really amused with my cousin who never took a computing course in her life. She is just not interested in it, and she won't even buy a computer. Of course, I tried to convince her that a computer would make her life easier, but she just wouldn’t give in.
I can’t persuade her to purchase a computer, even if I told her that she could do all her shopping on the web. I explained to her that she could even order her groceries and have them delivered where she lives if she has a computer. However, my cousin still refuses to buy a basic desktop computer and take a simple computing course. I even offered to teach her all she needs to know if she would get a stinking computer. Well, I guess some folks just have trouble evolving. - Why Should You Avoid Getting a Braindump Certification? By : M. Aslam
Generally speaking, Braindumps refers to lists of questions and answers from an actual IT certification exam. This dangerous, illegal and unethical trend is like a plague to IT profession as well as industry. - Why Is Boot Camp Training Popular For It Certifications? By : Caitlina Fuller
There are several ways to prepare for your Microsoft Certification exams and one of the preferred methods is Microsoft MCSE boot camp training. There are quite a few reasons why MCSE boot camp is so popular with Microsoft systems engineers. One of the reasons is MCSE bootcamps prepare you for many different Microsoft certification exams. This means you can accomplish a lot with just one time commitment of eight days. Experienced professionals who are already knowledgeable of Microsoft systems and platforms will find this program intensive, information filled, and very helpful. This is not for people who don’t already have significant experience or knowledge in the field because boot camps are intensive and advanced. The benefit is that you will be exposed to all the information you need to know in order to pass your IT certifications. - What To Expect When Taking Your First Cisco Certification Exam By : Chris Bryant, CCIE #12933
Cisco Certification: Taking Your First Certification Exam
You’ve studied hard you’ve practiced your configurations you’ve used your flash cards over and over again and finally, the big day is here. Your first certification exam! - What Paper or Computer Files Should You Keep By : Slavco Stefanoski
As business people we must deal with a great deal of paper and information from email and the net every day. You need to know however, that according to the "Pareto Time Management Rule," only 20% of all paper and information is important. That leaves 80% that is not important. It's just another decision to make as to whether this information makes your life better or not. - What Certification Should You Pursue After The Ccna ? By : Chris Bryant, CCIE #12933
Once you've got your CCNA, you're ready to move on to the next level, the Professional certifications. For years, Cisco had one Professional certification, the Cisco Certified Network Professional (CCNP) certification. Over time, Cisco has expanded this level of certifications to include the Cisco Certified Security Professional (CCSP) and Cisco Certified Voice Professional (CCVP).
With security and voice being the two most rapidly expanding areas of today's networks, some new CCNAs consider going after the CCSP or CCVP without first adding the CCNP to their resume. - Training Options For Mcse Certification By : Caitlina Fuller
Systems engineers who want a good job need to be MCSE certified if they want to work on Microsoft platforms. But, getting trained and certified is not always easy and does not always fit so well into people’s schedules. So, there are several training options for MCSE certification. - Training Options For It Certifications By : Natalie Aranda
IT (information technology) covers all aspects of managing and processing information. With IT Certification, you can develop, design, support, and manage networks, hardware and computer software.

Buying a CCNA / CCNP home lab is the best way to be totally prepared for your Cisco exams. Most home labs are put together one router or switch at a time, but many CCNA / CCNP candidates prefer to buy kits where you get multiple routers and switches, along with all the cables and other connection devices you'll need.
While this is a good idea, keep a few things in mind when purchasing Cisco home lab kits. - The Value Of It Certifications In Career Development By : Natalie Aranda
Information technology (IT) is the branch of engineering dealing with the use of computers and telecommunications, developing and maintaining systems as well as retrieving, storing and transmitting information. Therefore, any person wanting to develop a career in IT should be aware of the value of IT certifications.
Through education and certification, professionals gain the skills, knowledge, and validation needed to be recognized as an expert in diverse products or technologies. MCSE Certification, CCNA Certification, A+ Certification, and SAP Certification are just a few of the many credentials an IT professional may achieve. - The Value Of It Certification Boot Camps By : Natalie Aranda
There is no career field expanding quite as fast as the Information Technology field. Most experts predict this field will remain one of the fastest growing segments of the job market for many years to come. There is hardly a job that does not use computer technology to some degree or another and the demand for trained IT certified techs is reaching critical mass in many industries. One of the major problems within this growth industry is the rapid advances in technology. Training has to be continuous as new software is introduced or upgraded almost daily. One method of determining the level of training of a prospective employee is Certification.
Although online certification courses are becoming more and more popular, they are not always the best way to gain the needed skills. Many people work better with the help of instructors and in group learning situations. It is for exactly these kinds of people that the Certification Boot Camp has been developed. - The Value Of A Computer Information Systems Degree By : Morgan Hamilton
The invention of computers has changed the world. In this, the computer age, almost everything we do involves computers and the Internet. Communication, business, entertainment, and other aspects of human life rely on computers and related technology. It’s essential for people to adapt to the computer revolution by making themselves familiar with computer related knowledge. Computer information systems degree and similar courses can provide people with opportunities to benefit from the influence of computers.
Many parents these days are encouraging their children to consider a computer information systems degree for their future career. Parents can sense the trends of the present job market and they know that computer related degrees are a wonderful way of approaching college. A computer information systems degree provides a person with valuable knowledge that are in demand in most modern businesses. Knowledge about computers in today’s world gives a person an edge over individuals who are computer illiterate. - The Secrets To Pass It Certification Exams With Ease By : Natalie Aranda
How do you pass an IT Certification Exam with Ease? It may not seem this is a possibility to a person preparing to take one. The importance of the Certification process to the career of an IT tech and normal test anxiety are certainly going to make the whole certification process seem daunting. There are some ways to reduce this anxiety and make the entire test taking process much easier. The first thing is to realize is that the entire Certification process is designed for success. It is not meant to fail people or to reduce the number of IT techs. The goal is to create a standard knowledge level for IT techs not to weed out failures. Understanding this simple distinction and knowing that the entire system is designed to help you pass not to make you fail is the first step.
There are several ways to prepare for the test and all of them are important. There are hands on labs and extensive boot camps. There are books and study guides for each specific certification area. You can take a self test to identify your weak areas. All of these methods are designed to give you a contextual knowledge of the subject. A contextual knowledge goes beyond simple memorization of things and gives a complete understanding. It also helps to identify distracters. The idea of distracters is important because the exams are concerned with what is wrong as well as what is right. This is why the exam formats are given as multiple choice. The IT practice exam prepares you for this format. - The Pros And Cons Of It Training Boot Camps By : Natalie Aranda
Many technicians interested in improving their overall skill level have opted for IT training boot camps. They offer intensive training, and give plenty of hands on training, and most important they award the all important certificates that have become necessary for the advancement of the technicians career in the IT field.
So, what are the pros and cons of the IT training boot camp as compared with other more conventional certification programs? What are the factors that can help guide your decision? - The NM-16ESW Replaces Switches In Dynamips Switching Labs By : Barry Burdette
Complex switching labs can still be completed in Dynamips and GNS3. Cisco 3640 running c3640-jk9s-mz.124-16.bin IOS with an NM-16ESW installed in slot 1 can replace high level switches. - The Life Time Journey Of A Pair Of Glasses By : Anna Greening
Ever wondered how this delicate little assembly which we call a pair of glasses, (or spectacles if you prefer), comes into being, and where it ends up? - The Hidden Benefit Of Computer Certifications By : Chris Bryant, CCIE #12933
The web is covered with stories regarding the benefits of professional computer certification, and most of them are backed up with salary surveys and the like. While there’s certainly nothing wrong with making more money and having better job prospects, there’s one benefit of certification that many candidates forget about.
Confidence. - The Future Of Computer Certification Exams By : Chris Bryant, CCIE #12933
The format and difficulty of computer certification exams is constantly changing. When I took my first certification exam (Novell NetWare 3.1x CNA, January 1997), there was no such thing as a simulator question, and my practical skills really were not tested. The exams then were much heavier on memorization.
One factor that helped make up for that was that the Novell exams were adaptive. If you missed a question on a particular topic, you would continue to be asked questions about that topic until you got it right. You couldn't afford to be weak in any topic, because the exam would most likely find that out and keep hitting you with questions on that topic until you failed. - The Basic Requirements For Mcse Certification By : Natalie Aranda
The Microsoft Systems Engineer Certificate known as the MCSE is the basic fundamental certification program for an IT working in any Microsoft environment. The Certification concept has been developed in the rapidly changing and expanding field of computer technology to bring some order. When a person earns certification, employers and potential employers become confident that a certain standard threshold of expertise has been attained.
MCSE Certification is often a starting point for more advanced and specialized certifications. The basic requirements include normally at least one year of experience in the field implementing or administering a network operating system. The experience can also be in a client operating system or designing a network infrastructure. In order to earn the certificate, the candidate must pass a serious of examinations. There are four basic exams required that cover operating systems. Another exam tests and gives proof of expertise in design skills. Finally, two elective exams must be completed. These exams may be selected from a list of choices that include such diverse topics as security and implementation of various operating systems. - Taking A Look At Cisco's Ccvp Certification By : Chris Bryant, CCIE #12933
I hardly have to tell you how important voice technologies are in today's networks; what we all need to keep in mind to maximize our career potential is how important knowing voice is going to be tomorrow.
We've always got to look forward in IT, both in our work and out studies. Cisco, always the pioneer in technical certifications, now offers a Cisco Certified Voice Professional certification that is gaining a lot of attention from IT professionals looking to add to their skills and their resume. - Securing Your Network And Your Career With Cisco's Ccsp Certification By : Chris Bryant, CCIE #12933
You don't need me to tell you that security is the #1 concern in today's networks. With that in mind, your career path must include some security certifications, or you will be left behind.
Cisco's Cisco Certified Security Professional (CCSP) certification demands a candidate be well-rounded and well-versed in Cisco security measures. Besides the difficultly we've all come to expect from a Cisco exam, this five-exam path covers every major aspect of network security (from Cisco's viewpoint, anyway!) - Sap Training Courses, Its Future and Career Prospects By : Ryan Mutt
SAP is the world largest ERP software organization. The SAP certification exams are globally recognized. Read this article to find information on the career prospects of SAP training courses. - RIP (Routing Information Protocol) By : M. Aslam
RIP (Routing Information Protocol) is a distant vector routing protocol. RIP algorithm has been in use since the early days of ARPAnet. - Precisely What To Take Into Consideration In A Computer Monitor By : Matt Droves
A computer monitor is essential for almost any pc since it is what brings the realm of computers to individuals visually. You will find a number of different types of desktop monitor. One of the things to consider in a pc monitor, include the resolution of the monitor, it's dimensions, the type of display and the refresh quality of the monitor. The dimensions of the pixels in the monitor should also be considered when you are considering exactly what to watch out for in a computer monitor. - Passing Your Ccna And Ccnp: Configuring And Troubleshooting Router-on-a-stick By : Chris Bryant, CCIE #12933
For CCNA and CCNP candidates, it's hard not to laugh the first time you hear the phrase "router on a stick". Let's face it, that's a pretty silly term. But as those who have passed the CCNA and CCNP exams know, this is a vital exam topic that you must know how to configure and troubleshoot.
Basic Cisco theory states that for hosts in different VLANs to communicate, a Layer 3 device must be involved to handle the routing between the VLANs. That device is a router, and there are special considerations that must be taken into account for both the physical router itself and the configuration you'll be writing. - Passing The Cisco Ccna Exam: An Illustrated Guide To Router Modes By : Chris Bryant, CCIE #12933
When you're getting started on your CCNA studies, learning the different router modes is key to passing your Intro and ICND exams. But keeping those modes straight can be very difficult. (At least it was for me!) Let's take a look at the various router modes you'll need to know about to pass your CCNA, and use IOS Help to illustrate the different uses of each mode.
The first mode you'll see on a router (if the person before you logged off as they should have) is user exec mode. This is also the default mode a user is placed into when using Telnet to connect to a router. The prompt will look like this: - Passing The Ccna And Ccnp: Three Myths About Cisco Exams By : Chris Bryant, CCIE #12933
One of the drawbacks to the Internet is that it allows myths and "friend of a friend" stories to spread quickly, and usually the story becomes more exaggerated as it's passed along. Cisco exams are no exception. Here are three often-repeated myths and exaggerations regarding the CCNA and CCNP exams.
1. The survey you fill out before the exam determines the questions you'll get. Before you actually start your exam, Cisco presents you with a survey asking how you prepared and how comfortable you feel with certain technologies. It's a little awkward to rate yourself on Frame Relay, ISDN, etc., especially since the exam you're about to take covers those subjects. It's human nature to think that these questions impact your exam, but they do not. - Passing The Ccna And Ccnp: Home Lab Shopping On Ebay By : Chris Bryant, CCIE #12933
Whether you're just getting ideas for your Cisco home lab or adding to your existing lab, ebay is a great place to get ideas for your lab as well as pick up some great bargains.
Of course, the internet being what it is, there are always going to be a few people looking to take your money while shipping you inferior merchandise, or worse, no merchandise at all. While these "dealers" are in the minority, you still need to be careful when purchasing Cisco equipment on ebay. In this article, I'll give you several tips on browsing ebay ads for home lab ideas, and a few things to look out for when purchasing equipment on ebay.
For those of you just starting your Cisco certification pursuit, the idea of purchasing a home lab kit -- a set of routers, switches, and perhaps some cables and study guides -- seems like a good idea. Instead of putting your lab together one piece at a time, these kits allow you to get a head start on your studies. - Passing The Ccna And Ccnp: Cisco Home Lab Faq By : Chris Bryant, CCIE #12933
There is a real revolution today among CCNA and CCNP candidates. More and more of you are turning your back on "router simulators" and putting your own CCNA and/or CCNP Home Lab together, which is the best way to totally prepare to pass these tough Cisco exams.
I get hundreds of emails every month from CCNA and CCNP candidate who are putting together their first lab or adding to their existing one. I'm always glad to help with suggestions, and I thought I'd list five common questions regarding home labs here. - Passing The Ccna And Ccnp Exams: Setup Mode By : Chris Bryant, CCIE #12933
CCNA and CCNP candidates need to know all about Setup Mode, why a router goes into that mode, and as you'll see, how to get out of that mode. Practicing Setup Mode at work is a good way to get fired, though, so you need to practice this on your CCNA / CCNP home lab or rack rental. In this article, we'll take a look at a Cisco 2500 router going into setup mode and a few tips that will help you pass the exams and excel at your job.
First, why does a router go into Setup Mode in the first place? When a Cisco router boots up, the router looks into Non-Volatile RAM (NVRAM) for the startup configuration file. If such a file is not found, and the router has not been programmed to look to a TFTP server for this file, the router enters setup mode. - Passing Cisco’s Ccna And Ccnp Exams: Traceroute By : Chris Bryant, CCIE #12933
In preparation for your CCNA and CCNP exam success, you've got to learn to troubleshoot Cisco routers. And while ping is a great basic IP connectivity tool, it doesn't give you all the information you need to diagnose network connectivity issues.
Let's say you have six routers between CityA and CityB. You send a ping from A to B, and get this return: - Passing Cisco's Ccna And Ccnp Exams: Five Tips For Exam Day Success By : Chris Bryant, CCIE #12933
As you get ready to pass the CCNA or CCNP exams, you can feel quite a bit of stress as you enter your last week of study. Let's take a look at a few ways to reduce that stress.
1. Do not stay up late cramming. The CCNA and CCNP are not exams you're going to pass by cramming. "Cramming" is a study technique best left behind in junior high school. The CCNA can't be passed by memorization - you've got to know how Cisco technologies work. That leads us to the second point... - Passing Cisco Ccna And Ccnp Exams: Ping And Extended Ping By : Chris Bryant, CCIE #12933
I often tell CCNA and CCNP candidates that you do your best learning when you screw something up. I often get a funny look right after I say that, but the only way to develop your Cisco troubleshooting skills - the skills you'll need to pass your Intro, ICND, and CCNP exams - is by actually fixing configurations. Since your employer will take a dim view of you practicing these skills on his or her network, you better do so on your home lab!
Three essential tools for networking and CCNA/CCNP exam success are ping, extended ping, and traceroute. Today we're going to take a look at the ping that we're used to using for LAN issues, and the extended ping.
We're all familiar with "basic" ping, where you use the ping command followed by the IP address you want to confirm IP connectivity with. When you've got connectivity, you will see five exclamation points, as seen here: - Overview Of Microsoft Certification Training By : Natalie Aranda
The Microsoft Certification program is one of the most valuable certification programs available to the IT tech simply because Microsoft is a leader in the software field. The value of a Microsoft Certification is unquestioned. It increases the confidence of the individual who earns it and opens up professional opportunities. They become what is called a Microsoft Certified Professional, or MCP. This recognition is not lost on potential employers. The rapid growth and change of the IT environment has created a need for professional technicians who have demonstrated initiative above the norm.
Microsoft lists six steps in the Certification process. Identification of the proper Certification is the first step. There are many different ones covering the full spectrum of interests and skills. The second step is to gain hands on experience working with Microsoft systems. A full six months of work experience is recommended before considering attempting to earn a certification. This would be increased to one year for the advanced level certifications. The next step is to expand your experience with training. Microsoft training is conducted through formal classroom training or through a distance learning based network. E-learning programs are also available for self paced learning. There are videos and books available as well to supplement all three modes of training. It is vital to make sure that you are training for the correct certification. A MCSE training video, designed for the basic level Microsoft Certified System Engineer certification is a good place to start. - Overview Of Comptia A+ Certification By : Natalie Aranda
The field of computer technology is experiencing an explosive surge of growth, and the outlook is that this will continue unabated in the coming years. The concept of training and certification has become increasingly important for people pursuing a career in this field. The Computing Technology Industry Association (CompTIA) has introduced several Certifications to strengthen employee resumes and enable employers to judge the skills and training levels of prospective employees. The basic one is the A+ Certification.
The A+ Certification is a vendor-neutral test of the overall knowledge of computer hardware and operating systems. It covers the candidate’s ability to install, configure, fix, upgrade, and even troubleshoot personal computers. It covers skills in diagnosing and preventive maintenance as well as basic networking. The exam covers such domains as security, safety, and even environmental issues. - Network+ Exam Tutorial: Ports, Port Numbers, And Sockets By : Chris Bryant, CCIE #12933
If there's one thing that can be a bit confusing to many Network+ certification exam candidates, it's the concept of ports and sockets. Well, it was confusing to me when I got started with computer certifications! Let's take a look at ports and sockets, and why we need them in the first place.
Past Network+ exam tutorials have focused on how two PCs start communicating, but what we've got to keep in mind is that host PCs may and probably will have several different kinds of communications going on at the same time. A single PC may be sending email, receiving a Telnet request, and accessing the Internet at the same time. These conversations have to kept separate.. but how? - Network+ Exam Tutorial: Network Interface Cards (nics) By : Chris Bryant, CCIE #12933
Part of the challenge of passing the Network+ exam is learning about all the different types of hardware a network requires. Today we’ll take a look at a vital part of network connectivity, the Network Interface Card (NIC, pronounced “nick”).
The NIC is the device, or card, that gives the host a physical connection to the network. The NIC is generally an internal device, but one that can be removed and replaced with a different NIC. NICs are considered Physical layer devices and work at Layer 1 of the OSI model. - Network+ Exam Tutorial: Becoming A Master Troubleshooter By : Chris Bryant, CCIE #12933
Passing your Network+ exam is the first step on the way to becoming a master network troubleshooter, and that's where you need to be. The average network admin spends 90% of their time troubleshooting and 10% installing hardware and software, so you better be good at troubleshooting!
In my experience, there are two kinds of network troubleshooters in the world: - Network+ Exam Certification Tutorial: The Bus Topology By : Chris Bryant, CCIE #12933
The Physical layer of the OSI model isn't the most exciting or interesting to work with, but it's the foundation for everything we do in networking. The same goes for the physical side of networking - whether it's cable types, network topologies, or network cards, it's not necessarily the most exciting study you'll ever do, but it is the most important. After all, if a network has physical issues such as a bad Network Interface Card or mismatched cables, there's no way the network can work properly!
My next few Network+ exam tutorials will discuss the different network topology types, and we’ll start with a look at the dreaded bus topology. After we define it, I'll tell you why I call it "dreaded". - Network+ Certification Exam Tutorial: How And When To Use Virtual Lans (vlans) By : Chris Bryant, CCIE #12933
From your Network+ exam studies, you know that switches forward broadcasts, and that sounds great, but that's not always a good thing. A switch can have anywhere from 12 ports to 80 or more, and by default all hosts connected to that switch are going to be in the same broadcast domain. Let's say we have an 80-port switch. If one host connected to that switch sends a broadcast, by default, all of the other 79 hosts are going to receive the broadcast. That will unnecessarily take up our network's available bandwidth.
It gets worse. For some network services and protocols, a broadcast received by a host results in that receiving host transmitting a broadcast of its own. Then when all the hosts receive that broadcast, they all end up transmitting even more broadcasts. Pretty soon, all these broadcasts have snowballed into a broadcast storm, which can take up most of a network's bandwidth and make normal network operations almost impossible. - Network+ Certification Exam Tutorial: Ethernet Csma/cd Explained By : Chris Bryant, CCIE #12933
When you're studying for the Network+ exam, you've got a lot of new acronyms to learn! One of the basics is CSMA/CD, which stands for Carrier Sense Multiple Access with Collision Detection. That's quite a mouthful, but it's an important term to know for both your exam and real-world success.
On an Ethernet segment, hosts can send data at any time. As you might guess, that's a bit of a problem in itself, because if multiple hosts send data at the same time, a collision will occur and the data will become unusable. That's why CSMA/CD requires a host that wants to send data to listen first. Listen for what? Data being sent by another host. If the host hears data being transmitted, that host will not begin sending data itself. That's the "carrier sense" part of CSMA/CD. If that host hears nothing, the host will begin to transmit. - Network+ Certification Exam Tutorial: Dhcp And Rarp By : Chris Bryant, CCIE #12933
Part of passing the Network+ exam is mastering the many different protocols and services you're introduced to in your studies, and that's especially hard when two protocols do much the same thing! That's the case with RARP and DHCP, so let's take a close look at these two protocols and why we use them in the first place.
Whether you've been around networks for a while or are just getting started with your IT career, you'll quickly notice that many basic tasks in networking can be handled either statically or dynamically. By "statically", I mean configuring each device in question manually; by "dynamically", I mean having it done (almost) automatically. Generally, you're going to choose the dynamic method, and not because it's easier or quicker - it's because dynamic methods are much more adaptable to change, and today's networks are always changing. - Network+ Certification Exam Tutorial: Arp And Proxy Arp Explained By : Chris Bryant, CCIE #12933
In yesterday's Network+ tutorial, we talked about the importance of Address Resolution Protocol (ARP) in today's networks. A host PC must have the MAC and IP addresses of a remote host in order to send data to that remote host, and it's ARP that allows the local host to request the remost host to send the local host its MAC address through an ARP Request.
The ARP Request is a layer two broadcast, and like all L2 broadcasts it has a destination MAC address of ff-ff-ff-ff-ff-ff. Switches forward broadcasts, but routers do not, which brings up a basic problem. If there's a router between two hosts, how can one possibly send an ARP Request to the remote host, since routers do not forward broadcasts? - Network+ Certification Exam Tutorial: Address Resolution Protocol (arp) By : Chris Bryant, CCIE #12933
When you're studying for the Network+ exam, you've got to master the fundamentals of networking, because the Network+ is a hard exam to pass due to the range of information covered. One such fundamental is the Address Resolution Protocol, commonly referred to as ARP.
ARP operates at the Data Link layer of the OSI model, and its purpose is often overlooked. When Host A wants to send data to Host B, we know Host A must have a destination IP address for Host B (the Network layer address). What we tend to overlook is that Host A must also have a Layer 2 destination address for Host B -- in other words, it's got to have a destination MAC address for Host B. That's where ARP comes in. - Network+ / Ccna Certification Exam Tutorial: Port Numbers And Troubleshooting By : Chris Bryant, CCIE #12933
Passing the Network+ and CCNA exams demands that you know quite a few port numbers, but they're important to know when working with real-world networks as well. Before we discuss why, here's a partial list of important port numbers to know for these certification exams:
Ports 20 and 21 are used by File Transfer Protocol (FTP). - More Questions To Ask A Computer Training School Before Paying By : Chris Bryant, CCIE #12933
The decision to attend a computer training school is one of the most important you'll ever make, and even more important is which one to attend. Asking the right questions can give you an idea of whether a given IT school is a good investment. An earlier article I wrote on this subject was so popular that I thought I'd offer some more advice on the questions to ask before you write that check or take out that loan.
If the school offers a placement service, ask to talk to the people working in that department and ask them how they go about placing graduates. Most schools offer a list of companies that they've placed students with. Get this list and start calling some of these companies. Ask to speak to their HR department, and ask them for their opinion of the school. Even if they don't say a lot, their tone of voice can speak volumes. - More Computer Consulting 101 Hiring Tips (Part 2 of 2) By : Joshua Feinberg
Does your company need to retain the services of a competent computer consulting firm, but you have no idea how to really evaluate “competence”?
In the first part of this two-part series on Computer Consulting 101 hiring tips, we looked at why small businesses find it so difficult to hire good computer consulting companies, as well as four basic questions that you must be addressed when searching for a new computer consulting vendor. - Microsoft Vista Certification Tutorial: An Introduction To Windows Defender By : Chris Bryant, CCIE #12933
You don't have to be working on a Microsoft Windows Vista certification to know about the security problems that past versions of Windows have encountered. As a result, Microsoft is paying special attention to security with Vista, and one of the new features Vista features is Windows Defender.
What exactly are we defending against with Defender? Spyware. Spyware programs range from annoying (one pop-up banner after another) to downright destructive (capturing your computer's keystrokes). Windows Defender is designed to operate much like an antivirus program in that Defender will detect the offending spyware and then quarantine or delete the spyware. - Microsoft Vista Certification Exams Announced By : Chris Bryant, CCIE #12933
Microsoft Vista certification is on the way, and Microsoft recently announced the first Vista exams. In keeping with trends in certification, these particular exams are designed for different job roles. These exams are scheduled to be released in "early 2007", according to Microsoft's website:
MCITP - Microsoft Certified IT Professional - "Consumer Support Technician" and "Enterprise Support Technician" certifications - Microsoft Mcse Certification And Your Career Development By : Natalie Aranda
One of the most important certifications in the IT field is the MCSE certification. This is the Microsoft Certified Systems Engineer certificate and it covers a wide range of Microsoft based systems. The MCSE certificate can be earned in a large number of different ways. You can use classroom training, distance or online learning courses, or Microsoft’s own e-learning program. There are even programs that combine online learning with classroom training for those who benefit from a more personal approach.
The importance of Microsoft systems in the world of Information Technology (IT) can not be stressed too highly. The future is going to bring demands for specialized training beyond the current levels, and certification is going to be more than suggested, it is going to be required. In fact, this situation has already become the norm in many major organizations. - Microsoft Certification: The New Mcts Tracks And Exams By : Chris Bryant, CCIE #12933
Microsoft is revamping its certification tracks, and will eventually retire the familiar MCSE certificatons. The new certification setup is much like Cisco's, where there are specialist certifications to go along with the more general CCNA, then mid-level certifications such as the CCNP, and then a more-advanced practical exam modeled somewhat after the coveted CCIE certification.
Microsoft's new specialist exams are the Microsoft Certified Technology Specialist (MCTS) exams. As of March 2006, there were five separate MCTS Tracks. Three of them deal with .NET Framework 2.0; these are the Web Application, Windows Applications, and Distributed Applications certifications. Each of these separate certifications requires the candidate to pass two exams. There is also a one-exam SQL Server 2005 certification, as well as a BizTalk Server 2006 single-exam certification. - Microsoft Certification: Farewell To The Mcse By : Chris Bryant, CCIE #12933
Microsoft is in the middle of a major push to overhaul its certification program. Last year, they announced the new Microsoft Certified Architect (MCA) certification, which is not a written exam but rather a practical exam that will be graded by a board of examiners. Just applying for the certification will require 10 years' experience in IT as well as three years of practical experience as a network architect.
For those of us not quite ready for that, Microsoft has announced that it's also going to revise other certifications. The MCSE that we've all come to know and love is going to be a thing of the past. In its place will be a series of specialization exams and IP Professional certification tracks. - Microsoft Certification 101 By : Natalie Aranda
In the current job market, Microsoft certifications represent one of the richest and varied spectrums of job roles and responsibilities, which are embraced by industry professionals worldwide, that earning a specific credential provides an objective validation of their ability to successfully perform critical IT functions in a wide range of companies and industries.
Microsoft certification is the top effective way to achieve goals in long-term IT careers, being at the same time a useful tool for companies to develop and retain valuable IT professionals - Mcse? Ccna? Choosing The Right Computer Certification For Your Career By : Chris Bryant, CCIE #12933
When you’re choosing which computer certification to pursue next, you should also be formulating a plan for your career. Your time is precious, and you should never choose to pursue a certification because it’s “hot”. There are some hard questions you should ask yourself before deciding to pursue the CCNA, CCNP, CCVP, CCSP, CCIE, MSCE, or any of the many other vendor certifications that are out there.
Why do I want this certification? - Match Training Options With It Certifications By : Natalie Aranda
It is important to the career development of an IT tech to have proper certification. It is getting more important everyday as the IT field continues to grow. Computer based training is not something that is optional any longer. So, the question is no longer if you should pursue it or not, but rather where can you get it. There are several options.
It does not come as a surprise that IT training is available on the internet. There are quite a few sites offering computer based training, and preparations for Certification training. Online training, or distance training as it is often called, is a viable option in many different circumstances. Not everyone is in a position to abandon their jobs and take time off to attend onsite type of training. The major advantage of distance training is that you can work at your own pace. What is important is your own personal learning profile. Some people learn better in a hands on environment with the guidance of a trainer. Other people thrive on independent study and have the self discipline to make their own schedule and to adhere to it. - Keeping Calm On Ccna / Ccnp Exam Day By : Chris Bryant, CCIE #12933
When you wake up on exam day, one of two things is going to happen. Well, yes, you're going to pass or fail. But what I'm thinking of comes before that, and has a lot to do with how you perform on exam day.
You're either going to have a tremendous feeling of anticipation or the dreaded feeling of being nervous about it. - It’s 2006. Do You Know Where Your It Career Is? By : Chris Bryant, CCIE #12933
Whether you're thinking of starting a career with computers and information technology, or thinking about earning a professional certification such as the CCNA or MCSE to accelerate your career, there is no better time to start than today. Silicon Valley is hiring again, and while we all can't work for Google, IT hiring is at its highest level in years and the opportunities for driven, motivated individuals are unlimited.
I also know that for many of us, the holiday season is a good excuse to put off those studies! "I'll study for the CCNA after Thanksgiving..." "I'll start working on my CCNP after the New Year..." Well, guess what - the new year is here. - IT Certifications: What Types of Support Do Your Clients Need? By : Joshua Feinberg

After deciding on the career of a computer technician, there are a few things that people need to take care of in order to jump start their careers. There is a lot of computer based training that could help people improve their experience and their skill. There are several key certifications that are must haves when you decide to become a computer technician, including Cisco certifications, which are highly respected, Microsoft or MCSE certifications, and A+ certification.
Getting these certifications is a great asset because you will receive industry recognition for the knowledge and proficiency level that you are currently at without question. A MCSE certification means that you know the ins and outs of the most difficult Windows operating system and the Microsoft Windows Server system. It will also give you access to technical and product information that may be valuable for solving problems on the fly at work. While this may not be as important, Microsoft will also offer you discounts on many products and systems from different companies. In order to obtain a MCSE certification, a person must have at least one year of experience working with networking systems along with at least one year of implementing and administering a desktop operating system and designing a network infrastructure. When trying for this certification, it might be a wise choice to take one of the MCSE boot camps that are offered online. These courses are rigorous and expensive, but are usually worth the time and money. - Importance of SAP ERP Certification in Career Development By : Ryan Mutt
ERP is a complete business solution of any organization, no matter whether they are small or large. Read this article to find information on the importance of SAP ERP certification. - How To Succeed At A Computer Training School By : Chris Bryant, CCIE #12933
One of the best decisions you can ever make is to attend a computer training school. As I've written in several other articles, you have to ask the right questions before writing a check or taking out a student loan, but when you find the right school you are indeed on your way to a successful career.
There's a big difference between attending a tech school and excelling at the classes, though. Whether you just "float through" the school or really work hard is totally up to you. From my personal experience at such a school, I'd like to offer you one simple tip that will quadruple your chances of success at the school and in the job market. - How To Prepare For Microsoft Certifications By : Caitlina Fuller
Taking the Microsoft certification exams can be a very stressful event because so much is riding on passing the exams. However, there are a lot of ways to prepare for Microsoft Certifications that will help you become knowledgeable and take the exam with confidence. There are MCSE training videos, MCSE braindumps, and MCSE boot camps that are all very helpful in providing information that will help you prepare for certification. Another great way to see if the MCSE bootcamp and other preparations help you out is to simply take some practice tests. When you do you will have a good idea where you stand as far as information you know and what you need to learn. The different training videos, braindumps, and boot camps are all wonderful at preparing you to take your Microsoft Certification exams. However, if you really want to know where you stand then give the practice tests a try. You will quickly see how your studying has paid off and will be able to determine what areas you are weak in and need to study more. - How To Earn Cisco’s Firewall Specialist Certification By : Chris Bryant, CCIE #12933
Security is a hot topic in today's networks, and will continue to be for a long time to come. With that in mind, you must consider adding a Cisco security certification to your resume and firewall skills to your skill set.
It's quite a jump from the CCNA to the CCSP (Cisco Certified Security Professional), and Cisco has made that leap more manageable by adding Specialist certifications. These certifications can give quite a boost to both your resume and your skill set, and act as a great "stepping stone" to the CCSP. - How To Choose The Right It Certification Boot Camps By : Natalie Aranda
The field of IT training has become one of the biggest growth areas in the entire employment and training arena. The demand for trained technicians has outstripped the supply for years now, and each passing day and new technological development has made this more acute. One of the new methods that have emerged in recent years is the IT Certification Boot Camp.
The entire concept of IT certification has emerged as an important part of the overall training environment. College degree programs were becoming more of an introduction to the complex field, and there was a demand for skilled technicians beyond what the colleges could provide. On the other hand, employers were left with no sure method of evaluating the skill level of prospective employees. The Certification revolution addressed this problem. The Certifications gave a measuring stick for the learning level of the IT technician. - How To Become A Cisco Vpn Specialist By : Chris Bryant, CCIE #12933
There's quite an emphasis on security in today's networks, and that's reflected in Cisco's certification tracks. Cisco offers a CCIE Security track and the Cisco Certified Security Professional (CCSP) intermediate-level certification, but there is no real equivalent to the CCNA on the security side. Instead, Cisco offers several different Security Associate certifications.
The good news is that you’ve got a lot of security specializations from which to choose; the bad news is that you’ve got a lot of choices! In choosing a specialization, take some time to choose a certification that will be of practical use to you in your current position or in your “dream job”. - How To Become A Cisco Ccnp By : Chris Bryant, CCIE #12933
Congratulations on your decision to earn your CCNP certification! As a CCIE, I can tell you that Cisco certifications are both financially and personally rewarding.
To earn your CCNP, you first have to earn your CCNA certification. Then you're faced with a decision - take the three-exam CCNP path, or the four-exam path? They're both quite demanding, so let's take a look at each path. - How Does A Mcse Boot Camp Work? By : Natalie Aranda
One of the best methods of securing IT training, and preparing for your MCSE Certification examination is the boot camp. MCSE stands for Microsoft Certified System Engineer. The MSCE boot camp gives you the intensive training that you need to not only pass the examination, but also to handle the work afterwards. The boot camp concept takes its name from military basic training and although it does not resemble that in the discipline area, it certainly earns its name for its intensity.
A typical MCSE boot camp lasts around two weeks. The fee for the camp includes air transportation to the camp site, and lodging during the duration of the course. If air transportation and lodging are not needed, these expenses will be deducted from the cost. Meals are also included in these packages. Students will take up to seven certification examinations during the boot camp. The class room work will be directed toward preparation for each examination. Students will be working also on the actual hardware and software under the guidance of instructors who are experience in all Microsoft platforms. Most boot camps have 24/7 lab access available to the students. - Four Important Commands For Your Ccna / Ccnp Home Lab By : Chris Bryant, CCIE #12933
More CCNA and CCNP candidates than ever before are putting together their own home practice labs. It's more affordable than it ever has been, and I receive emails daily from new CCNAs and CCNPs who say it's the best thing they could have done to improve their studies.
There are some commands you can configure on your lab routers that won't necessarily be on your CCNA or CCNP exams, but they will make life a lot easier for you. Let's take a look at just a few of these. - Five Questions To Ask Before Attending A Computer Tech School By : Chris Bryant, CCIE #12933
As with any field, there are good technical training schools, and bad ones. When you sign up with one of these schools, you’ve made a significant investment in time and money. You deserve to know everything about the school and your job prospects after leaving that school before you put down your hard-earned money. The problem is, sometimes it’s hard to know the right questions to ask.
The point of this article is not to bash technical training schools. That’s how I got my start in IT eight years ago, and today I’m a CCIE™ and own my own Cisco training company and my own consulting firm. - Do You Know How Spyware Effects Your Computer? By : kim chi

Making the decision to attend a computer tech school can be one of the best decisions of your life. Another great decision is to tap a hidden wealth of knowledge that is right before every student at schools such as ECPI and ITT, but very few students take advantage of it.
When you're attending a computer training school, you must avoid the mentality that some other students will have - "I gotta go to school, I gotta be here, I can't wait to leave and go home". When you're preparing for a career working with computers, you've got to take advantage of every learning experience you can get, and that includes getting to know the most valuable resource at your school - your teachers! - Computer Training And It Certifications By : Natalie Aranda
In the competitive world of the internet, computer training is necessary to gain skills and knowledge in order to get the validation you need to be recognized as an expert IT professional confronting all those opportunities and career challenges that have never been greater than today.
An IT certification is a common a prerequisite to get a job or a salary increase, hence professional certifications are a necessity and not just a marketing strategy to sell determined software or useless courses. Both computer training and IT certification are the best way to demonstrate your skills and expertise in any given technical field to present to prospective employers. - Computer Repair Online Schools Can Be Easy And Fun By : Michael Bustamante

You can get the training you need for troubleshooting, repairing, and maintaining PCs through an online computer repair school. They provide a very convenient course of study, allowing you to receive all the study materials, information, and knowledge necessary for success in this interesting occupation. - Computer Help - Where and How to Get It By : Jonathan Hutchinson
Well there's no denying it - No matter how new or how well maintained our computers are, we all encounter computer problems sooner or later. The good news is that we don't have to face them alone.

Computer Consulting 101 Preventative Medicine - Computer Certification: Four Tips For Maximum Performance During The Exam By : Chris Bryant, CCIE #12933
There are plenty of articles out there about how to prepare for a computer certification exam. However, there are also things you can do to increase your chances of success on exam day during the most important part of the entire process -- the time that you're actually taking the test.
I've taken many a certification exam over the years, and helped many others prep for theirs. Here are the five things you must do on exam day to maximize your efforts. - Computer Certification: Become A Utility Player By : Chris Bryant, CCIE #12933
In baseball, a "utility player" is one who plays more than one position. These players are usually backups, but they have a job in the major leagues because of their value to the team; since they can play more than one position, they have that much more value to their employer.
Too often in IT, workers become either LAN or WAN engineers, knowing little if anything about the other side. Many LAN administrators I worked with knew little about routing and switching, while many WAN engineers I knew not only didn't know much about the LAN side of their network, but they didn't want to know anything about the servers! - Comptia Network+ Certification Exam Tutorial: Virus Attacks And Antivirus Programs By : Chris Bryant, CCIE #12933
Whether you’re preparing to pass the Network+ or Cisco CCNA certification exam or not, you must not underestimate the importance of antivirus programs and virus definition updates. With all the attention we pay to viruses and their prevention, I feel a little silly even saying that. But….
If there's one thing you must have working at full capacity in your network, it's the antivirus programs. - Comptia Network+ Certification Exam Tutorial: The Five Ip Address Classes By : Chris Bryant, CCIE #12933
Passing the CompTIA Network+ certification exam and going on to become a subnetting expert is mastering the basics of IP addressing, and that means knowing the different classes, their default masks, and what these masks mean. Let’s get started!
Part of every IP address indicates the network the host is part of, and the other part identifies that particular host. You need to be able to look at an IP address and determine the network and host portions, and you do that by determining the class of the address. - Comptia Network+ Certification Exam Tutorial: Hubs, Repeaters, Bridges, And Switches By : Chris Bryant, CCIE #12933
To pass your Network+ certification exam, you must know the differences between hubs, repeaters, bridges, and switches. The differences are straightforward for the most part, so let's examine the basic purpose of these devices.
Hubs and repeaters both work at the Physical layer of the OSI model. They do not help to direct traffic toward the proper destination, as routers and switches do. Their purpose in the network is simply to make the signal strong enough to reach its destination, by regenerating the signal. Hubs and repeaters both take an incoming data signal and make a clean, strong copy of the signal. Otherwise, the signal would suffer from attenuation, the gradual weakening of a signal as it gets farther and farther away from the source. - Comptia Network+ Certification Exam Tutorial: Hot Sites, Warm Sites, And Disaster Recovery By : Chris Bryant, CCIE #12933
Part of passing the Network+ exam and being an outstanding network administrator is being prepared for disaster. Sometimes that's a disaster on a relatively small scale, such as a drive failure. If you're running data backups on a regular basis (and you are, aren't you?), you're prepared for that issue.
What is your network's disaster recovery plan from a true disaster, either natural or man-made? What if the entire building your servers are in disappeared tonight? What is your plan if that happens? In today's world, that's not a rhetorical question. Disaster recovery is taken to the next level by preparing a cold site, warm site, or hot site at another physical location. - Comptia Network+ Certification Exam Tutorial: Dhcp And Dhcp Relay Agents By : Chris Bryant, CCIE #12933
As a CompTIA Network+ exam candidate, you’re probably familiar with DHCP – but just in case, we’re going to review DHCP basics here and then go into a discussion of DHCP Relay Agents.
When it comes to assigning an IP address to all the PCs on our network, along with their network mask, DNS server location, and more, we've got two choices on how to do it: - Comptia Network+ Certification Exam Tutorial: Antivirus Programs By : Chris Bryant, CCIE #12933
In the first part of this CompTIA Network+ certification exam tutorial, we looked at the different types of viruses and other invaders trying to get into our network, and how antivirus programs help to stop them. Today, we’ll discuss some tips on how to get the maximum protection from your antivirus program.
I strongly recommend you choose an antivirus program that offers automatic updates. If you rely on manual updates - that is, relying on remembering to go out and check for updates yourself instead of having them automatically downloaded when new updates are available - I can practically guarantee you're going to forget to do so, and this can be a fatal mistake for both your network and your career. - Comptia A+ Certification Reality Check By : Natalie Aranda
The Computing Technology Industry Association offers a number of Certifications that enable IA techs to make their resumes look stronger and that also give employers a measuring stick for evaluating the skill level of an applicant. The A+ Certification is one of these and is considered an entry level general purpose vendor-neutral certification. It covers a wide range of skills related to the maintenance of personal computers. It also covers basic networking, security, safety, and even environmental issues.
A+ Certification training is available worldwide and is designed to prepare the student for the certification exam. There is a common misconception, however, concerning A+ Certification training. Many aspiring techs view it as a basic training course for beginners to the IA technology field. In planning their career path, they view the A+ training as the starting place for their overall training. This is a mistake. The Certification training programs are designed to prepare the student to take the comprehensive exam to receive the Certification. A certain skill level and educational background is going to be assumed of the students taking the training. If you have not received the elementary training, you are going to be over your head. - Cisco Routing: "ip Default-network" Vs. Default Static Routes By : Chris Bryant, CCIE #12933
One point of confusion for some CCNA and CCNP candidates is the difference between configuring a static default route and using the Cisco routing command ip default-network.
At first glance, they appear to do the same thing. Both configure a destination to which packets should be routed if there is no more specific route in the routing table. - Cisco Routing For The Ccna And Ccnp: Administrative Distance By : Chris Bryant, CCIE #12933
The textbook definition of "administrative distance" is simple enough: "the measurement of a protocol's believability". It's not enough to know the definition, however you've got to know when AD comes into the picture and when it does not.
When a packet needs to be routed, the router looks in its routing table for the next-hop IP address the packet should take to get to the destination. There may be more than one matching path, in which case the router will look for the "longest match". The route that has the longest match - the route with the most bits in the mask set to "1" - will be the route that is used. - Cisco Home Lab Tutorial: Buying And Building A Frame Relay Switch By : Chris Bryant, CCIE #12933
One of the major topics on your CCNA and CCNP exams is Frame Relay. Additionally, Frame Relay is one of the most popular WAN technolgies in today's networks. Getting hands-on experience with Frame Relay in Cisco networks isn't just a good idea, it's a necessity. Let's face it, your employer is going to get a little touchy if you start experimenting with your network's Frame Relay setup.
To practice all your important Frame Relay commands for your exams, you need a working Frame Relay cloud in your home lab. A production network's Frame cloud consists of a lot of Frame switches, but if you choose wisely, a single Cisco router can act as your home lab's entire Frame cloud! - Cisco Certifications For Networking Professionals By : Natalie Aranda
In order to achieve the second tier of the Cisco Pyramid, one needs to pass the Cisco Certifications for Network Professionals exam. This exam will prove that a network professional will be able to install, configure, and troubleshoot converged local and wide area networks with one hundred to five hundred or more nodes. They will also be able to manage routers and switches that are part of the network core, along with edge applications that integrate voice, wireless and security into the network. One needs to pass a total of four tests to achieve this title and they will need to renew this certification every three years.
If you are having trouble passing these required tests or just need some extra help, many websites offer a CCNP boot camp which is usually a rigorous and effective course that will improve your chances of passing the test with ease. These classes are no joke and can last from eight AM in the morning to late into the evening, and will be either a great review for the test or it will help you learn the daunting information that will be on the test. - Cisco Certification: The Most Important Study You'll Ever Do Is.... By : Chris Bryant, CCIE #12933
All of us are familiar with the pyramids of Egypt. These magnificent structures have stood for thousands of years, withstanding extreme heat and other factors that would bring down an ordinary structure.
When we look at these pyramids, we instinctively look toward the peak. We tend to do the same with the Cisco Learning Pyramid. If you're not familiar with this, Cisco uses a pyramid to illustrate how the CCIE is at the peak of the Cisco certification structure, with the CCNP in the middle and the CCNA at the bottom. - Cisco Certification: The Importance Of Building Your Own Home Lab By : Chris Bryant, CCIE #12933
CCNAs and CCNA candidates hear it all the time: “Get some hands-on experience”. From my personal experience climbing the Cisco certification ladder, I can tell you firsthand that there is no learning like hands-on learning. No simulator in the world is going to give you the experience you will get cabling and configuring your own routers.
Whenever I mention this to one of my students, they always say it costs too much. The truth is, it is cheaper now to build your own CCNA and CCNP lab than it has ever been. The secret? Used routers. - Cisco Certification: The "secret" Key To Getting Your Ccna And Ccnp By : Chris Bryant, CCIE #12933
Whether you're working on your CCNA or CCNP, Cisco certification exams are the most demanding computer certification exams in the IT field. Cisco exams are not a test of memorization, they're a test of your analytical skills. You'll need to look at configurations and console output and analyze them to identify problems and answer detailed questions. To pass these demanding exams, you've got to truly understand how Cisco routers and switches operate - and the key to doing so is right in front of you.
The debug command. - Cisco Certification: Suggested Home Lab Setups By : Chris Bryant, CCIE #12933
When you make the decision to put your own home lab together for your CCNA and CCNP studies (a very wise decision, if I may say so!), the hardest part is figuring out how to spend your budget. Do you spend it all on the routers and go with a cheaper 1900 switch, knowing that the 640-801 (CCNA), 640-821 (Intro), and 640-811 (ICND) exams now place a premium on knowing the ins and outs of a 2950 switch? Do you buy a frame relay switch? Do you buy an access server?
One factor to keep in mind when you're starting to put your lab together is that you don't have to put it all together at one time. With some careful planning, you've got a lab that you can use for your Intro studies, perhaps add a router or two for ICND study, and then some more devices for your CCNP study.
