Professional certifications have been an important part of the computing industry for many years and will continue to become increasingly more important. Many reasons exist for these certifications, but the most popularly cited reason is credibility. All other considerations equal, the certified employee, consultant, or job candidate is considered more valuable than one who is not. Cisco Certifications: Training Paths and Exams The Cisco Certified Internetwork Expert (CCIE) certification program has been available since the early 1990s. This long-standing certification has maintained a high degree of credibility and is recognized as a certification that lives up to the name “expert.” The CCIE certification process requires passing a computer-based test and a...

Professional certifications have been an important part of the computing industry for many years and will continue to become more important. Many reasons exist for these certifications, but the most popularly cited reason is that of credibility. All other considerations held equal, the certified employee/consultant/job candidate is considered more valuable than one who is not. Objectives and Methods The most important and somewhat obvious objective of this book is to help you pass the CCNA exam (640-507). In fact, if the primary objective of this book was different, then the book’s title would be misleading; however, the methods used in this book to help you pass the...

Internetworking—the communication between two or more networks—encompasses every aspect of connecting computers together. Internetworks have grown to support vastly disparate end-system communication requirements. An internetwork requires many protocols and features to permit scalability and manageability without constant manual intervention. Large internetworks can consist of the following three distinct components:

This document serves as a design guide for those intending to deploy a site-to-site VPN based on IP Security (IPsec). The designs presented in this document focus on Cisco IOS VPN router platforms. The primary topology described in this document is a hub-and-spoke design, where the primary enterprise resources are located in a large central site, with a number of smaller sites or branch offices connected directly to the central site over a VPN. A high-level diagram of this topology is shown in Figure 1....
