From the CCNA to the CCIE, ISDN is one of the most important technolgies you’ll work with. It’s also very common in the field; ISDN is frequently used as a backup connection in case an organization’s Frame Relay connections go down. Therefore, it’s important to know ISDN basics not only for your particular exam, but for job success.
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.
Candidates can register for the CCNA exam (640-801 exam or 640-821 INTRO or 640-811 ICND ) at Pearson VUE or Prometric testing centers.
The Cisco Certified Network Associate (CCNA) Certification is meant for career enhancement as well as gaining knowledge of the LAN/WAN technologies currently available for implementation. Hence, CCNA Certification can be obtained by IT professionals who have been a part of the industry for a considerable time and are interested in furthering their career in terms of role enhancement and salary. Individuals who are beginning their career and want to move towards LAN/WAN management may also pursue the certification, as it is a basic level certification and there are no prerequisites.
Unshielded Twisted Pair (UTP) is a cable that has four pairs of wires twisted inside it to eliminate electrical interference. UTP cables are connected using RJ-45 connectors that have eight connector pins. The data equipment that is used for internetworking is classified as Data Terminal Equipment (DTE e.g. router interfaces) and Data Communication Equipment (DCE e.g. A WAN connects DTEs through DCE network).
Cisco has defined a hierarchical model known as the hierarchical internetworking model. This model simplifies the task of building a reliable, scalable, and less expensive hierarchical internetwork because rather than focusing on packet construction, it focuses on the three functional areas, or layers, of your network:
What are your IT Career and Certification expectations for year 2004? While certifications can give you an edge, going for just any certification doesn’t help. What is your career focus? New or old activities, what is your focus? New does not always translate to good or wise. It makes sense to review and analyze trends that will affect your career in 2004.
This article focuses on another important network model, the Cisco hierarchical network design model. Very different that the OSI model, this model is used as the basis for designing Cisco networks for security and performance. The article provides an overview of the roles and responsibilities of each of the model’s 3 layers.

The first thing that I noticed when I opened the box containing these materials was the quality of what I had received. Anyone who has bought Microsoft Official Curriculum knows that, if you are lucky, you will receive paperback books and, if you are not lucky, you will receive your materials in a three ring binder (that you have to assemble!).
