CCNA® Wireless Study Guide

Introduction

Welcome to CCNA Wireless Study Guide, a comprehensive guide that covers everything you need for Cisco's new exam 640-721. For readers who are new to Cisco certifications, there is a well-defined structure to the different levels that network administrators can achieve.

Cisco's current certification structure has the following five levels of certification:

• Entry level

• Associate

• Professional

• Expert

• Architect

This book is written for the associate level of certification. Cisco considers this level to be the "apprentice or foundation level" for network administrators.

Cisco has recently broadened its associate-level certifications to include not only a certification for routing and switching (CCNA) and design (CCDA) but also more targeted associate-level certifications for security (CCNA Security), wireless (CCNA Wireless), and voice (CCNA Voice). These new certifications target specific areas of Cisco technology and are to be used as stepping-stones for the professional and expert levels of certification that Cisco offers.
