The CCNA Exam Prep, Second Edition, is an in-depth training guide for the new CCNA (Cisco Certified Network Associate) certification from Cisco. Published in the popular Exam Prep series, the book incorporates all the topics tested in this newly-revised exam, including new security, VPN, wireless, IPv6, and troubleshooting coverage. The authors emphasize sub-netting concepts because this is historically a difficult roadblock for Cisco certification candidates. This Exam Prep covers all the exam objectives and will give you a thorough understanding of each testable concept in addition to real-world configuration examples for configuring a wide range of Cisco devices. The Prep begins with an objectives quick reference and includes chapter summaries with a list of key terms, exercises, review questions, and an exam on chapter content with detailed answers. Exam Preps include notes, tips, cautions, and exam alerts to help you focus on important issues. If you are preparing for this exam you will find the Exam Prep series to be the complete certification solution for the CCNA exam.
