- How To Excel In A Technical Job Interview
Ah, the technical interview. Nothing like it. Not only does it cause anxiety, but it causes anxiety for several different reasons.
How many people will be asking questions? From experience I can tell you there’s nothing like walking into a room and seeing nine people on the other side of the table. - How To Start Your Career In Information Technology
Many newcomers to Information Technology get an overly-optimistic picture of the field from tech school ads that continually make note that "an average MCSE salary is $80.000 a year!".
And if someone's thinking of getting into IT and goes on the internet to do some research, they're met with the opposite end of the spectrum - complaint after complaint about how much IT is a terrible field, you can't break in, there's no room for newcomers, etc. - Your Information Technology Career: Certification Vs. Experience
Whether you're just starting your Information Technology career, or wanting to get further ahead in your current IT career, you have probably thought about earning one of the many popular computer certifications such as the Cisco Certified Network Associate (CCNA) certification, or the MCSE (Microsoft Certified Systems Engineer) cert.
A major point of frustration for individuals pursuing one of these certifications is a possible lack of experience with these technologies. Many future CCNAs or MCSEs simply stop trying to earn their certification, feeling that their lack of experience will hold them back. - Cisco Ccna / Ccnp Home Lab Tutorial: A Guide To Cable Types
When you're putting your CCNA and/or CCNP home lab together, you're not just buying routers and switches you're creating a blueprint for success. There is no better way to learn about how real Cisco routers and switches work than to work with the real thing!
Of course, it's not enough to just get the routers and switches you've got to have the right cables and other devices to allow them to communicate. Let's take a look at the different cables and connectors you need to know about when putting together your CCNA and CCNP home labs. - Your Information Technology Career: Beware The Comfort Zone
I've seen it happen time and again to programmers, network engineers and administrators, and other IT personnel. They get a solid IT position, a good-paying job, and they get comfortable. They stop keeping up with the latest technologies, they stop studying, they no longer keep their CCNA, MCSE, and other industry certifications up-to-date.... and then one day, their comfortable job is gone.
Maybe they get laid off, maybe the company moves and they don't want to move with it... but for one reason or another, they're in the worst position possible. They have no job, and they have allowed their IT skills to deteriorate to the point where they are no longer employable.
If you're in IT, you must be constantly learning. You must continually take the long view, and ask yourself three important questions. First, where do you want to be in three years? Second, what are you doing now in order to reach this goal? And finally, if you were laid off today, are your current skills sharp enough to quickly get another job? - Three Ways To Jumpstart Your It Career
We all get stuck in ruts from time to time, and that happens on the job as well. You've thought about doing something different with your information technology career, but just haven't quite gotten around to it yet. Sound familiar?
You can make 2006 the best year yet for your IT career. There are several simple steps you can take to accelerate your career - but you have to take the step, not just think about it! - How To Start A Career In The Computer Field
If you're considering a career working in Information Technology - a fancy way of saying "working with computers" - congratulations! I can tell you from personal experience that it's one of the best decisions you'll ever make. I can also tell you from personal experience that it is never too late to begin!
I started my IT career 10 years ago, and it was a tough decision. I was 34 years old, and really knew next to nothing about computers. I decided to attend a technical school to get my career started, and it was the best decision I've ever made. Ten years later, I write ebooks and teach classes dealing with different facets of networking, I’ve earned the most difficult computer certification in the world, and I've never been happier. The same thing can happen for you. - Cisco Ccna / Ccnp Certification Tutorial: Frame Relay End-to-end Keepalives
One of the first things you learned about Frame is that the LMI also serves as a keepalive, or a heartbeat - and if three consecutive LMIs are missed, the line protocol goes down. There's a limitation to LMI as a keepalive, though. The LMI is exchanged only between the DTE and the closest DCE. The LMI is therefore a local keepalive that does not reflect any possible issues on the remote end of the virtual circuit.
Taking the LMI concept to the next logical level, Frame Relay End-To-End Keepalives (FREEK, one of the least-heard Cisco acronyms for some reason) are used to verify that endpoint-to-endpoint communications are functioning properly. - Cisco Tac : An Introduction To The Cisco Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is Cisco's tech support center, and they've got some very talented people working there. Before you pick up the phone to call the TAC, though, you should do your best to resolve the problem and document each step along the way. One of the first things the TAC will do is ask what you've done so far to resolve the issue, and giving them an accurate answer is a huge step toward getting the problem resolved.
If you're used to "tech support" where calls are prioritized by the order in which they come in, the TAC will open your eyes! Cisco's TAC uses four priority levels to determine which cases should be handled first: - Cisco Ccnp Certification Bsci 642-901 Exam Training: The Eigrp Adjacency
EIGRP is an important part of real-world networking as well as being a major topic on the 642-901 CCNP BSCI exam. As with any networking topic, before you try to master intermediate and advanced skills, you must master the fundamentals. It doesn’t get any more fundamental than the EIGRP adjacency process – and it doesn’t get any more important, because without that adjacency, we don’t have an EIGRP deployment!
In today’s CCNP tutorial, we’ll work with R1 and R2, two Cisco routers communicating over a serial interface. EIGRP is already running on R2’s serial interface, but was just enabled on R1’s serial interface. The EIGRP adjacency process begins with R1 sending an EIGRP Hello packet to the multicast address 224.0.0.10 in an attempt to find potential neighbors.
