Chapter 4, "Bridges/Switches and LAN Design"
· LANs--in particular, the various forms of Ethernet--are covered in this chapter. The logic behind
transparent bridging and LAN switches is also discussed in depth, as is the operation of the Spanning-
Tree Protocol. LAN switch configuration on the 1900 series LAN switch, using its IOS CLI, is
covered as well.
·
Chapter 5, "Network Protocols"
· This chapter discusses TCP/IP and NetWare protocols, as well as their configuration on Cisco routers.
IP addressing is covered in great depth, with many tools to prepare you for questions on the exam.
NetWare initialization flows and encapsulations are detailed as well.
·
Chapter 6, "Routing"
· Routing protocols are used by routers to dynamically learn routing information. This chapter covers
the types of routing protocols, with a detailed look at distance vector routing protocol logic. The
implementation of IP RIP and IGRP, and Novell RIP and SAP, is covered here as well.
·
Chapter 7, "Understanding Access List Security"
· Network security is a very broad subject area. This chapter focuses on the security topics covered on
the CCNA exam--namely access lists. IP standard access lists, both numbered and named, are
discussed as well. Likewise, numbered and named IPX and SAP access lists are described.
·
Chapter 8, "WAN Protocols and Design"
· This chapter covers point-to-point serial links as the first type of WAN link and then discusses the
various data link protocols used on point-to-point links, both for concepts and configuration. Frame
Relay is covered in great detail, largely because point-to-point links and Frame Relay are the two
most popular WAN options in routers today. Finally, this chapter covers ISDN protocols and their use
in simple dial-on-demand (DDR) environments.
Additional scenarios in Chapter 9 provide a method of final preparation with more questions and exercises.
Example test questions and the testing engine on the CD allow simulated exams for final practice.
Each of these chapters uses several features to help you make best use of your time in that chapter. The fea-
tures are as follows:
·
"Do I Know This Already?" Quiz and Quizlets
--Each chapter begins with a quiz that helps you
determine the amount of time you need to spend studying that chapter. The quiz is broken into
subdivisions, called "quizlets," that correspond to a section of the chapter. Following the directions at
the beginning of each chapter, the "Do I Know This Already?" quiz will direct you to study all or
particular parts of the chapter.
·
Foundation
--This is the core section of each chapter that explains the protocols, concepts, and
configuration for the topics in the chapter.
·
Foundation Summary
--Near the end of each chapter, a summary collects the most important tables
and figures from the chapter. The "Foundation Summary" section is designed to help you review the
key concepts in the chapter if you score well on the "Do I Know This Already?" quiz, and they are
excellent tools for last-minute review.
