Like the certi?¬?cation itself, the book should help readers become literate in the
use of switches, routers, and the associated protocols and technologies. The second goal is
that someone who completes the book and the CCNA certi?¬?cation should be able to use
these skills to select, connect, and con?¬?gure Cisco devices in an internetworking environment.
In particular, the book covers the basic steps and processes involved with moving data
through the network using routing and Layer 2 switching.
Readers interested in more information about the CCNA certi?¬?cation should consult the
Cisco website at http://www.cisco.com/en/US/learning/le3/le2/le0/le9/
learning_certi?¬?cation_type_home.html. To schedule a Cisco certi?¬?cation test, contact

Chapter Organization
This book is divided into eight chapters and an appendix and is designed to be read in order
because many chapters build on content from previous chapters.
?– Chapter 1, ???Review of Cisco IOS for Routers and Switches,??? provides a review of
the Cisco IOS. This is an assumed knowledge for readers, but this chapter provides
a brief review of command structure that is used throughout the other chapters of
the book.
