| Article Title :: Cisco CCNA Certification: Five Key Combinations You Should Know |
| |
| 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.
The up arrow on your keyboard is great for repeating the last command you typed. Let's say you mis-enter an access-list. Instead of typing it (read full article) |

| Article Title :: Cisco CCNP Certification: The BGP Weight Attribute |
| |
| When you're studying for the CCNP certification, especially the BSCI exam, you must gain a solid understanding of BGP. BGP isn't just one of the biggest topics on the BSCI exam, it's one of the largest. BGP has a great many details that must be mastered for BSCI success, and those of you with one eye on the CCIE must learn the fundamentals of BGP now in order to build on those fundamentals at a later time.
Path attributes are a unique feature of BGP. With interior gateway protocols such as OSPF and EIGRP, administrative distance is used as a tiebreaker when two routes to the same destination had different next-hop IP addresses but the same prefix length. BGP uses path attributes (read full article) |

| Article Title :: Cisco Certification: The "Secret" Key To Getting Your CCNA And CCNP |
| |
| 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.
Of course, there is no single "debug" command. Using IOS Help, you can quickly see that there are hundreds of these debugs, and I want to mention imme (read full article) |

| Article Title :: Cisco CCNA / CCNP Home Lab Tutorial: Buying And Configuring An Access Server |
| |
| A Cisco access server is generally the last item a CCNA or CCNP candidate has on their mind when they're putting together a home lab. The thinking tends to be that since this router isn't really doing anything in the production part of your practice lab, it's not really important.
Once you have more than two devices in your home lab, though, you'll realize that constantly moving the console cable around from one router to another gets very tiresome. That's what an access server does for a home lab - it allows you to connect your PC to a single device when working in your home lab, with no need to constantly disconnect and reconnect the console cable. The console cable will be co (read full article) |

| Article Title :: Cisco Routing For The CCNA And CCNP: Administrative Distance |
| |
| 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.
Consider the following three routes from a fictional Cisc (read full article) |

| Article Title :: The Future Of Computer Certification Exams |
| |
| 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. (read full article) |

| Article Title :: Keeping Calm On CCNA / CCNP Exam Day |
| |
| 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. You're driving to the exam center, excited about the exam. You're much like a football player, slapping another player on the helmet or the shoulder pads before the game starts. (Warning: Don't try this on the exam proctor.) You know there's a challenge ahead, but you're looking forward to it. In you (read full article) |

| Article Title :: Cisco Certification: In What Order Should You Take Your CCNP Exams ? |
| |
| When you choose to pursue your Cisco Certified Network Professional certification, you've got some decisions to make right at the beginning. Cisco offers a three-exam path and a four-exam path, and you select the order in which you'll take and pass the exams.
While every CCNP candidate has to make their own decision, I'd like to share some thoughts based on my personal experience and the experiences of CCNPs worldwide.
The solid foundation of networking knowledge you built as a CCNA will help you a great deal on your BSCI (Building Scalable Cisco Internetworks, 642-801) exam. This is the most common exam to take first, and I'd recommend you do so as well. While ther (read full article) |

| Article Title :: Securing Your Network And Your Career With Cisco's CCSP Certification |
| |
| 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!)
You must hold a valid CCNA certification to earn your CCSP.
