| Article Title :: 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.Adding to this are those in IT who will stop everything they're doing at (read full article) |

| Article Title :: Cisco CCNA Exam Tutorial And Case Study: VLANs and IP Connectivity |
| |
| In this CCNA case study, we'll take some basic switching and trunking theory and put it into action. We have two routers (R2 and R3) along with two switches (SW1 and SW2). R2 is connected to SW1 at fast 0/2, and R3 is connected to SW2 at fast 0/3. Both routers have IP addresses on the 172.12.23.0 /24 network.
For these routers to be able to ping each other, the switches must be able to communicate. These are two 2950 switches, and they're connected via two crossover cables. Before we worry about the router connectivity, let's make sure the trunk link is up between the switches with the "show interface trunk" command.

| Article Title :: Cisco CCNP / BSCI Exam Tutorial: The BGP Attribute MED |
| |
| Your BSCI exam and CCNP certification success depend on mastering BGP, and a big part of that is knowing how and when to use the many BGP attributes. And for those of you with an eye on the CCIE, believe me - you've got to know BGP attributes like the back of your hand. One such BGP attribute is the Multi-Exit Discriminator, or MED.
The MED attribute is sent from a router or routers in one AS to another AS to indicate what path the remote AS should use to send data to the local AS.
That sounds a little confusing on paper, so let's walk through an example. R1 is in AS 1, and R2, R3, and R4 are in AS 234. R4 is advertising a loopback into BGP, and R1 has two possible (read full article) |

| Article Title :: Cisco CCNA / CCNP Home Lab Tutorial: Using 2520 Routers |
| |
| I know from experience that part of the excitement and anxiety of putting together your own CCNA / CCNP home lab is deciding what to buy! While you can make a workable home lab out of almost any combination of Cisco routers and switches, some routers are better suited for home lab work than others because they can fill multiple roles.
My personal favorite is the Cisco 2520. This router has four serial interfaces, making it an ideal frame relay switch. Don't forget that just because you're using a router as a frame switch, you can still use its routing capabilities. One setup I use is to use three of the four serial interfaces for frame switching and the fourth interface as a poi (read full article) |

| Article Title :: Passing Your CCNA and CCNP: Configuring And Troubleshooting Router-On-A-Stick |
| |
| 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.The router will be connected to a switch via a FastEthernet port (o (read full article) |

| Article Title :: Passing The Cisco CCNA Exam: An Illustrated Guide To Router Modes |
| |
| 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:R1>You can't write or add to a configuration in this mode, but you ca (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.Ad (read full article) |
