| Article Title :: Cisco CCNA Certification Exam Tutorial: OSPF Hub-And-Spoke |
| |
| CCNA certification demands that you master the basics of OSPF, and for many studying for the CCNA exam, their first exposure to OSPF is a hub-and-spoke configuration. That's a tough way to get started, because a hub-and-spoke configuration built over an NBMA technology such as Frame Relay requires quite a bit of attention to detail. Let's take a quick look at several common OSPF configuration errors and how to avoid them on your CCNA test.
Make sure the hub is the designated router and that there are no backup designated routers. This is done by setting the OSPF interface priority to zero on the spoke routers. This not only ensures that the hub wins the DR election with its defa (read full article) |

| Article Title :: Cisco Certification: The Joy Of Hex |
| |
| Cisco certification candidates, particularly CCNA candidates, must master binary math. This includes basic conversions, such as binary-to-decimal and decimal-to-binary, as well as more advanced scenarios involving subnetting and VLSM.There’s another conversion that might rear its ugly head on your Cisco exam, though, and that involves hexadecimal numbering.Newcomers to hexadecimal numbering are often confused as to how a letter of the alphabet can possibly represent a number. Worse, they may be intimidated – after all, there must be some incredibly complicated formula involved with representing the decimal 11 with the letter “b”, right?Wrong.The numbe (read full article) |

| Article Title :: Five Questions To Ask A Computer Training School Before Signing Up |
| |
| As with any field, there are good technical training schools, and bad ones. When you sign up with one of these schools, you’ve made a significant investment in time and money. You deserve to know everything about the school and your job prospects after leaving that school before you put down your hard-earned money. The problem is, sometimes it’s hard to know the right questions to ask.The point of this article is not to bash technical training schools. That’s how I got my start in IT eight years ago, and today I’m a CCIE™ and own my own Cisco training company and my own consulting firm.Before I ever put down the first dime, though, I asked some tough questions (read full article) |

| Article Title :: Cisco CCNA Certification: Why You NEED Hands-On Practice! |
| |
| CCNA and CCNP candidates hear it all the time: “you have to get some hands-on experience to pass the exams”.Candidates tend to think that’s just so they can solve the simulator problems, but that’s only the more obvious reason.First, I want to make it clear that I’m not bashing learning from books you have to learn theory before you can really know what’s going on in the first place. The key is that to truly understand routing and switching processes, you’ve got to have that hands-on experience.So if the simulator questions are the more obvious reason to get hands-on experience, what are the less obvious reasons?Glad you asked!You see wha (read full article) |

| Article Title :: Cisco CCNP Certification: Introduction To BGP |
| |
| Cisco certification candidates are introduced to BGP at the CCNP level, but the reaction to its introduction always reminds me of something I see often as the CCNA level.Whenever I teach distance-vector protocols in my Ultimate CCNA Boot Camp or Fast Track classes, I make sure my students understand the many rules of distance-vector routing thoroughly. After that, we move on to OSPF and link-state routing.And what do I tell my students before we move on to OSPF and link-state? "Take all that great stuff you just learned about distance-vector routing and put it aside, because none of it applies here!"That's about the time I get astonished looks and a few things thrown (read full article) |

| Article Title :: Cisco CCNA Certification Exam: Five Frame Relay Details You Must Know |
| |
| When you're studying for your CCNA exam on the way to earning this coveted Cisco certification, the details can seem overwhelming! In this article, I'll point out five Frame Relay details that you must keep in mind when you're on your way to the CCNA exam!
Inverse ARP starts working as soon as you open the serial interface. This protocol performs dynamic Frame Relay mapping, but you don't have to enable it - it's already enabled as soon as you enter the command "encapsulation frame-relay".
When you're configuring Frame Relay map statements manually, remember that you're mapping the local DLCI to the remote IP address.
When you run "show frame map", the (read full article) |

| Article Title :: Cisco CCNP / BSCI Certification Exam: Five OSPF Details You Must Know |
| |
| Preparing for your BSCI exam on your way to the Cisco CCNP certification, you can quickly get overwhelmed by the details! Here are five commonly overlooked points you should keep in mind when it comes to your OSPF studies.
The virtual link command includes the area number of the transit area, and if authentication is being used on Area 0, the virtual link command must include the authentication statement. Since the virtual link is a logical extension of Area 0, it stands to reason that it has to be configured with the authentication type and password configured on Area 0.
OSPF requires no seed metric when routes are being redistributed into an OSPF domain. The defau (read full article) |

| Article Title :: Microsoft Certification: Farewell To The MCSE |
| |
| Microsoft is in the middle of a major push to overhaul its certification program. Last year, they announced the new Microsoft Certified Architect (MCA) certification, which is not a written exam but rather a practical exam that will be graded by a board of examiners. Just applying for the certification will require 10 years' experience in IT as well as three years of practical experience as a network architect.
For those of us not quite ready for that, Microsoft has announced that it's also going to revise other certifications. The MCSE that we've all come to know and love is going to be a thing of the past. In its place will be a series of specialization exams and IP Profession (read full article) |

| Article Title :: Why Get a Microsoft MCSE Certification? |
| |
| In the years of the dot com boom and bust, the Microsoft MCSE Certification has gotten its eye blackened over an over. Paper Microsoft MCSE's who were excellent at finding brain dumps and passing exams gave the Microsoft MCSE Certification a bad name.
