Отрывок из книги

First, a loud callout to Troy McMillan, who was instrumental in putting this book together. He spent countless hours combining and summarizing my work from the CCENT and CCNA ICND2 study guides into what is a really nice review guide for the CCNA Routing and Switching certification. Thank you, Troy!

Thanks to Ken Brown, who always keeps me working hard and makes sure I am headed in the right direction. This is no easy task for Ken!

Chapter 1: Network Fundamentals In Chapter 1, you will learn the basics of the Open Systems Interconnection (OSI) model the way Cisco wants you to learn it. There are plenty of review questions to help you.

Chapter 2: LAN Switching Fundamentals This chapter will provide you with the Ethernet foundation you need in order to pass the composite exam. Data encapsulation is discussed in detail in this chapter as well. And as with the other chapters, this chapter includes review questions to help you.
