| Article Title :: Passing Cisco's CCNA and CCNP: Ping And Extended Ping |
| |
| 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. Today we're going to take a look at the ping that we're used to using for LAN issues, and the extended ping.We're all familiar with (read full article) |

| Article Title :: Passing Cisco's CCNA and CCNP Exams: The 'VLAN.DAT' File |
| |
| CCNA and CCNP candidates who have their own Cisco home labs often email me about an odd situation that occurs when they erase a switch's configuration. Their startup configuration is gone, as they expect, but the VLAN and VTP information is still there!Sounds strange, doesn't it? Let's look at an example. On SW1, we run show vlan brief and in this abbreviated output see that there are three additional vlans in use:SW1#show vlan br10 VLAN0010 active20 VLAN0020 active30 VLAN0030 activeWe want to totally erase the router's startup configuration, so we use the write eras (read full article) |

| Article Title :: Passing Cisco's CCNA and CCNP Exams: Five Tips For Exam Day Success |
| |
| As you get ready to pass the CCNA or CCNP exams, you can feel quite a bit of stress as you enter your last week of study. Let's take a look at a few ways to reduce that stress.1. Do not stay up late cramming. The CCNA and CCNP are not exams you're going to pass by cramming. "Cramming" is a study technique best left behind in junior high school. The CCNA can't be passed by memorization - you've got to know how Cisco technologies work. That leads us to the second point...2. Get lots of rest. By far, this is the most overlooked factor on exam day. The CCNA and CCNP exams are going to demand your best. You're going to be performing subnetting, binary and hex conversions, analyzi (read full article) |

| Article Title :: Cisco CCNA / CCNP Certification: How And Why To Build An Etherchannel |
| |
| CCNA and CCNP candidates are well-versed in Spanning-Tree Protocol, and one of the great things about STP is that it works well with little or no additional configuration. There is one situation where STP works against us just a bit while it prevents switching loops, and that is the situation where two switches have multiple physical connections.You would think that if you have two separate physical connections between two switches, twice as much data could be sent from one switch to the other than if there was only one connection. STP doesn't allow this by default, however in an effort to prevent switching loops from forming, one of the paths will be blocked.SW1 and SW2 are (read full article) |

| Article Title :: Passing The CCNA and CCNP Exams: Setup Mode |
| |
| CCNA and CCNP candidates need to know all about Setup Mode, why a router goes into that mode, and as you'll see, how to get out of that mode. Practicing Setup Mode at work is a good way to get fired, though, so you need to practice this on your CCNA / CCNP home lab or rack rental. In this article, we'll take a look at a Cisco 2500 router going into setup mode and a few tips that will help you pass the exams and excel at your job.First, why does a router go into Setup Mode in the first place? When a Cisco router boots up, the router looks into Non-Volatile RAM (NVRAM) for the startup configuration file. If such a file is not found, and the router has not been programmed to look (read full article) |

| Article Title :: Cisco CCNA / CCNP Certification: OSPF E2 vs. E1 Routes |
| |
| OSPF is a major topic on both the CCNA and CCNP exams, and it's also the topic that requires the most attention to detail. Where dynamic routing protocols such as RIP and IGRP have only one router type, a look at a Cisco routing table shows several different OSPF route types.R1#show ip route
Codes:C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGPIn this tutorial, we'll take a look at the difference between two of these route types, E1 and E2. (read full article) |

| Article Title :: Cisco CCNA Certification: How To Approach The Post-Cert Job Interview |
| |
| Okay, you did it! You earned your Cisco Certified Network Associate certification.Now what?People who pass the CCNA exam fall into one of three categories. You may be just entering the IT field you may be working on the LAN side and want to move to the WAN side (that's where I was when I passed the CCNA), or you may already work on the WAN side of the network, and you want to move up the ladder.One way or the other, you're going to have to face the dreaded job interview. Some CCNAs do really well in interviews, and some don't. I've been on both sides of that interview, and I have a few pointers for you to be one of those who do well and get that job.Be confiden (read full article) |

| Article Title :: Cisco CCNA Certification: Four Tips To Use DURING The Exam |
| |
| There are plenty of articles out there about how to prepare for the CCNA exam. However, there are also things you can do to increase your chances of success on exam day during the most important part of the entire process -- the time that you're actually taking the test.I've taken many a certification exam over the years, and helped many others prep for theirs. Here are the five things you must do on exam day to maximize your efforts.1. Show up on time. Yeah, I know everyone says that. The testing center wants you there 30 minutes early. So why do so many candidates show up late, or in a rush? If you have a morning exam appointment, take the traffic into account. If it's a p (read full article) |

| Article Title :: Cisco Certification: The Importance Of Building Your Own Practice Lab |
| |
| CCNAs and CCNA candidates hear it all the time: “Get some hands-on experience”. From my personal experience climbing the Cisco certification ladder, I can tell you firsthand that there is no learning like hands-on learning. No simulator in the world is going to give you the experience you will get cabling and configuring your own routers.Whenever I mention this to one of my students, they always say it costs too much. The truth is, it is cheaper now to build your own CCNA and CCNP lab than it has ever been. The secret? Used routers.The word “used” turns off a lot of people not many of us buy used computers or used servers. Cisco routers, though, are robust I personal (read full article) |

| Article Title :: What Certification Should You Pursue After The CCNA? |
| |
| Once you've got your CCNA, you're ready to move on to the next level, the Professional certifications. For years, Cisco had one Professional certification, the Cisco Certified Network Professional (CCNP) certification. Over time, Cisco has expanded this level of certifications to include the Cisco Certified Security Professional (CCSP) and Cisco Certified Voice Professional (CCVP).With security and voice being the two most rapidly expanding areas of today's networks, some new CCNAs consider going after the CCSP or CCVP without first adding the CCNP to their resume.While it's temping to hurry up and get a Cisco security or voice certification, the best thing you can do for yo (read full article) |
