| Article Title :: Cisco CCNA / CCNP Certification Exam: Attending A Video Boot Camp |
| |
| When you're studying for the CCNA and CCNP exams, you've got a lot of different choices when it comes to training. One popular choice is choosing one of the many "boot camps" and five-day in-person courses that are out there. I've taught quite a few of these, and while many of them are good, they do have drawbacks.Of course, one is cost. Many employers are putting the brakes on paying for CCNA and CCNP boot camps, and most candidates can't afford to pay thousands of dollars for such a class. Then you've got travel costs, meals, and having to possibly burn your own vacation time to take the class. Add in time away from your family and boot camps become impractical for many CCN (read full article) |

| Article Title :: Cisco CCNA / CCNP Home Lab Tutorial: The 2501 Router |
| |
| To be truly prepared for your CCNA and CCNP exams, you need real hands-on experience with real Cisco routers and switches. However, a production network is a really bad place to practice your configurations, but an excellent way to get fired and/or sued. The key to becoming a true CCNA and CCNP is assembling your own Cisco home lab.
You don't have to spend a lot of money to do so; used Cisco equipment is cheaper than ever. It's robust as well - I've bought literally hundreds of used routers and switches over the years and have had very few problems. I owe much of my skill to practicing configurations and troubleshooting in my own home lab.
2501 routers are fantastic (read full article) |

| Article Title :: Cisco CCNP / BCMSN Exam Tutorial: Switches, QoS, And Cisco's Networking Model |
| |
| QoS is a big topic on your BCMSN and CCNP exams, and for good reason. As more and more traffic flows through today's networks, accurately applying QoS to both your routers and switches becomes more important.
Note the phrase "accurately applying". You must have a plan in place before you start configuring QoS on your switches, and to create such a plan you should use Cisco's Three-layer Hierarchical Model.
This model breaks switches down into three main groups - Access, Distribution, and Core. You're familiar with these groups from your CCNA studies, and now you've got to apply this knowledge.
The QoS workload should be borne by the Access and Distribut (read full article) |

| Article Title :: Cisco CCNP / BCSI Exam Tutorial: Broadcasts And The IP Helper-Address Command |
| |
| While routers accept and generate broadcasts, they do not forward them. This can be quite a problem when a broadcast needs to get to a device such as a DHCP or TFTP server that's on one side of a router with other subnets on the other side.
If a PC attempts to locate a DNS server with a broadcast, the broadcast will be stopped by the router and will never get to the DNS server. By configuring the ip helper-address command on the router, UDP broadcasts such as this will be translated into a unicast by the router, making the communication possible. The command should be configured on the interface that will be receiving the broadcasts.

| Article Title :: Why Computer Certifications Really Don't Matter |
| |
| I am currently a Network Administrator that supports about 100 Servers and 2000 Clients that has 8 years experience in Network Engineering. This article explains why certifications really dont matter.When I was in school all that my classmates talked about was how you need this certification and that certification. Now that I am responsible for interviewing technicians I learned that they really dont matter.How many times did your Interviewer ask you to see your actual certification. NEVER or almost NEVER. As long as you know the material you can say you have any certification you want. Since 95% of employers will never really check does it make it right to lie about what certifica (read full article) |

| Article Title :: Cisco CCNA / CCNP Exam Tutorial: Five Debugs You Must Know |
| |
| To pass the BSCI exam and move one step closer to CCNP certification success, you've got to know how and when to use debug commands to troubleshoot and verify network operations. While you should never practice debug commands on a production network, it's important to get some hands-on experience with them and not rely on "router simulators" and books to learn about them.When it comes to RIP, "debug ip rip" is the primary debug to use. This debug will show you the contents of the routing update packets, and is vital in diagnosing RIP version mismatches and routing update authentication issues.You know how to use the variance command to configure unequal-cost load-sharing wit (read full article) |

| Article Title :: How To Become A Cisco VPN Specialist |
| |
| 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”.On (read full article) |

| Article Title :: Cisco CCNA Certification Exam Tutorial: The OSI Model's Physical Layer |
| |
| To pass your CCNA exam and earn this coveted certification, you've got to master the seven layers of the OSI model and what each layer does. For those of you taking the two-exam path, you can expect quite a few OSI model questions on the Intro exam. In this seven-part series, we'll spend some time taking a look at each of the OSI model layers, starting with the Physical layer.Often, CCNA candidates ask if the OSI model has any practical uses for network administrators. I used to wonder the same thing, and I can now tell you that the answer is definitely yes!The OSI model isn't something you want to memorize and then forget about, as using the OSI model gives you a structu (read full article) |

| Article Title :: Cisco CCNP Certification / BSCI Exam Tutorial: Route Summarization Basics |
| |
| As you earn your CCNA and CCNP certification, you're going to have to get comfortable with manually summarizing routes. This isn't just another reason to learn binary math (although it's a good one!), but summarizing routes is a true real-world skill that can help your network operate more efficiently. So the question isn't just how to summarize routes, it's why.When you summarize routes in RIP, IGRP, EIGRP, or OSPF, you're replacing a series of routes with a summary route and mask. With RIP, IGRP, and EIGRP, this actually lessens the size of the routing update packet itself - multiple routes are replaced with the summary route. For instance, the routes 8.0.0.0/8, 9.0.0.0/8, 1 (read full article) |
