Introduction

This book includes newsample questions never before in print. Offering numerous samplequestions available nowhere else, this book will help you pass the640-802 CCNA exam on your first attempt.

The 640-802 CiscoCertified Network Associate (CCNA) is the composite exam associatedwith the Cisco Certified Network Associate certification.Candidates can prepare for this exam by taking the InterconnectingCisco Networking Devices Part 1 (ICND1) v1.0 and theInterconnecting Cisco Networking Devices Part 2 (ICND2) v1.0courses. This exam tests a candidate's knowledge and skillsrequired to install, operate, and troubleshoot a small to mediumsize enterprise branch network. The topics include connecting to aWAN; implementing network security; network types; network media;routing and switching fundamentals; the TCP/IP and OSI models; IPaddressing; WAN technologies; operating and configuring IOSdevices; extending switched networks with VLANs; determining IProutes; managing IP traffic with access lists; establishingpoint-to-point connections; and establishing Frame Relayconnections.

The following topicsare general guidelines for the content likely to be included on theCisco Certified Network Associate exam. However, other relatedtopics may also appear on any specific delivery of the exam

Describe how anetwork works
Configure, verify and troubleshoot a switch with VLANs andinterswitch communications
Implement an IP addressing scheme and IP Services to meet networkrequirements in a medium-size Enterprise branch officenetwork.
Configure, verify, and troubleshoot basic router operation androuting on Cisco devices
Explain and select the appropriate administrative tasks requiredfor a WLAN
Identify security threats to a network and describe general methodsto mitigate those threats
Implement, verify, and troubleshoot NAT and ACLs in a medium-sizeEnterprise branch office network.
Implement and verify WAN links
