| Article Title :: Computer Training School Tutorial: Know Your Instructor |
| |
| Making the decision to attend a computer tech school can be one of the best decisions of your life. Another great decision is to tap a hidden wealth of knowledge that is right before every student at schools such as ECPI and ITT, but very few students take advantage of it.
When you're attending a computer training school, you must avoid the mentality that some other students will have - "I gotta go to school, I gotta be here, I can't wait to leave and go home". When you're preparing for a career working with computers, you've got to take advantage of every learning experience you can get, and that includes getting to know the most valuable resource at your school - your teachers (read full article) |

| Article Title :: Cisco CCNA Exam Tutorial: The Best Time To Schedule Your Exam |
| |
| In preparing for CCNA exam success, one of the basic steps is to schedule your exam! And when should you do that?
Schedule your exam NOW.
I can hear you now -- " Why should I schedule my exam now? I haven’t started studying yet!"
From experience, I can tell you that this technique works. People complain about timetables and deadlines, but the truth is that people do their best work with a deadline. “Stress” is not the dirty word that we’ve made it out to be. A diamond is only a lump of coal that was put under pressure.
I wish I had a nickel for every time I’ve heard this:
"I’ll schedule my exam when I’m ready." (read full article) |

| Article Title :: Cisco CCNP Exam Tutorial: Defining Collision Domains |
| |
| CCNA exam success depends on mastering the fundamentals, and two important fundamentals are knowing exactly what the terms "collision domain" and "broadcast domain" mean. In this free Cisco tutorial, we'll take a look at the term "collision domain" and how a collision domain is defined.
A collision domain is an area in which a collision can occur. Fair enough, but what "collision" are we talking about here? We're talking about collisions that occur on CSMA/CD segments, or Carrier Sense Multiple Access with Collision Detection. If two hosts on an Ethernet segment transmit data at exactly the same time, the data from the two hosts will collide on the shared segment. CSMA/CD exists (read full article) |

| Article Title :: Cisco CCNP / BCMSN Exam Tutorial: Dynamic Trunking Protocol (DTP) |
| |
| When you're studying to pass the BCMSN exam on the way to earning your CCNP certification, you're going to add to your CCNA knowledgebase every step of the way. Nowhere is that more than configuring a trunk between two switches.
You know that IEEE 802.1Q ("dot1q") and ISL are your two choices of trunking protocols, and you know the main differences between the two. What you might not have known is that there's a third trunking protocol that's running between your Cisco switches, and while it's a transparent process to many, you had better know about it for your BCMSN and other CCNP exams!
The Cisco-proprietary Dynamic Trunking Protocol (DTP) actively attempts to neg (read full article) |

| Article Title :: Cisco CCNA Exam Tutorial: Five ISDN Details To Remember |
| |
| CCNA exam success depends on mastering many technologies that are new to you, and few exam topics have more details than ISDN. ISDN isn't just for your CCNA exam studies, though. While ISDN is dismissed by many, the fact is that there are many small and mid-size networks out there that use ISDN as their backup to frame relay. Some of these companies have spoke networks that use ISDN to connect to their hub as well, so it's a great idea to know ISDN configuration and troubleshooting for your real-world career as well as passing the CCNA. With that in mind, let's take a look at five common ISDN errors and how to avoid them.

| Article Title :: Cisco CCNP / BSCI Exam Tutorial: EIGRP Route Summarization |
| |
| Summarizing routes is a vital skill to learn to pass the BSCI exam and get one step closer to earning your CCNP. The actual binary conversions are only part of the test, though! You've got to know how to correctly apply the summary routes, and that differs from one protocol to the next. In the last few CCNP / BSCI tutorials, we've looked at using the "area range" and "summary-address" commands to perform OSPF route summarization. Today, we'll take a look at summarizing routes in EIGRP.
We'll use the following four loopback addresses in this example:
Loopback 16, 16.16.16.16 /32
Loopback 17, 17.17.17.17 /32
Loopback 18, 18.18.18.18 /32 (read full article) |

| Article Title :: CCNP / BCMSN Exam Tutorial: VLAN Trunking Protocol (VTP) |
| |
| Passing the BCMSN exam and getting one step closer to the CCNP certification means learning and noticing details that you were not presented with in your CCNA studies. (Yes, I know – you had more than enough details then, right?) One protocol you’ve got to learn more details about is VTP, which seemed simple enough in your CCNA studies! Part of learning the details is mastering the fundamentals, so in this tutorial we’ll review the basics of VTP.
In show vtp status readouts, the "VTP Operating Mode" is set to "Server" by default. The more familiar term for VTP Operating Mode is simply VTP Mode, and Server is the default. It's through the usage of VTP modes that we can plac (read full article) |

| Article Title :: Cisco CCNA Exam Tutorial: Five OSPF Hub-And-Spoke Details You Must Know! |
| |
| CCNA exam success depends greatly on knowing the details, and if there's one protocol that has a lot of details, it's OSPF! This is true particularly of hub-and-spoke networks, so in this CCNA OSPF tutorial we'll take a look at some of the more important hub-and-spoke OSPF details. This will help you in working with real-world networks as well, since this OSPF network type is one of the more typical network topologies.
In OSPF, the hub must become the designated router (DR). The DR election's deciding value is the OSPF interface priority, and the default value is 1. It's not enough to set the hub's OSPF interface to 2, however, since the spoke routers must not become the DR or B (read full article) |

| When you earned your CCNA, you thought you learned everything there is to know about RIP. Close, but not quite! There are some additional details you need to know to pass the BSCI exam and get one step closer to the CCNP exam, and one of those involves RIP update packet authentication.
You're familiar with some advantages of using RIPv2 over RIPv1, support for VLSM chief among them. But one advantage that you're not introduced to in your CCNA studies is the ability to configure routing update packet authentication.
You have two options, clear text and MD5. Clear text is just that - a clear text password that is visible by anyone who can pick a packet off the wire. I (read full article) |

You’ve scheduled your exam you’ve created a document to track your study time you’ve planned exactly when you’re going to study. Now the plan must be carried out, without exception.
