1). 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.

3). Cisco CCNA Certification: Five Key Combinations You Should Know By : Chris Bryant, CCIE #12933
When you start studying for your CCNA and CCNP exams, many books will present you with a huge list of keystroke shortcuts for use on Cisco routers. While the 640-801, 811, and 821 exams may ask you about one or two of these, you really have to get hands-on experience with these commands to master them. Even better, there are some key combinations that Cisco routers mention, but then don't tell you what they are! Let's take a look at a few of the more helpful key combinations, and conclude with the "secret" way to stop a ping or traceroute.

4). 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: R1#ping 172.

5). Cisco CCNA Certification: The (Many) Different Kinds Of Switching By : Chris Bryant, CCIE #12933
When you're studying for your CCNA exam, whether you're taking the Intro-ICND path or the single-exam path, you're quickly introduced to the fact that switching occurs at Layer 2 of the OSI model. No problem there, but then other terms involving switching are thrown in, and some of them can be more than a little confusing. What is "cell switching"? What is "circuit switching"? Most confusing of all, how can you have "packet switching"? Packets are found at Layer 3, but switching occurs at Layer 2.

6). 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. Anticipation is a great thing to feel on exam day.

7). 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.
