Publisher Comments:

CCNA Official Exam Certification Library, Third Edition, is the newest edition of the all-time best-selling CCNA self-study preparation package. This comprehensive review and practice package is designed for the latest CCNA 640-802 exams. The two books contained in this package, CCENT/CCNA ICND1 Official Exam Certification Guide, Second Edition, and CCNA ICND2 Official Exam Certification Guide, Second Edition, present complete reviews and a more challenging and realistic preparation experience. The books are updated to cover all the new 640-802 exam objectives, such as security, wireless, IPv6, and troubleshooting.

Please note that while this is the Third Edition of the Library, the two books inside are Second Editions. This is correct, and the editions align differently because of changes in the names of the exams, from the old INTRO and ICND to the new ICND1 and ICND2 formats.

What can you do with the CCNA Official Exam Certification Library?

  • Assess your knowledge with chapter-opening quizzes
  • Review key concepts with Exam Preparation Tasks
  • Practice with hundreds of exam questions on the CD-ROM
  • Learn about more complex topics with over one hour of video training

CCNA Official Exam Certification Library, Third Edition, presents you with an organized test preparation routine through the use of proven series elements and techniques. “Do I Know This Already” quizzes open each chapter and allow you to decide how much time you need to spend on each section. Chapter ending Exam Preparation Tasks sections help drill you on key concepts you must know thoroughly and help increase your speed in answering questions, a difficult hurdle many candidates face on the new exams. Final Preparation chapters guide you through tools and resources to help you craft your final study plan. Special troubleshooting sections help you master the complex scenarios you will face on the exam.

The companion CD-ROMs contain a powerful testing engine with over 400 questions that allow you to focus on individual topic areas or take complete, timed exams. The test engine also includes simulation and testlet questions, and all questions are available in study mode and test mode. The assessment engine also tracks your performance and provides feedback on a chapter-by-chapter basis, presenting question-by-question remediation to the text.

The bonus DVDs contain more than 60 minutes of personal video mentoring from the author focused mainly on the topic of subnetting. These videos help bring difficult subnetting concepts to life and make learning easy.

 

Well-regarded for its level of detail, assessment features, and challenging practice questions, this completely revised and updated edition provides you with more detailed information and more realistic practice exercises than any other CCNA study guide, enabling you to succeed on the exam the first time.

 Best-selling author and senior instructor Wendell Odom shares preparation hints and test-taking tips, helping you to identify areas requiring further study and to improve your conceptual and hands-on knowledge. The material is presented in a concise manner, focusing on increasing your understanding of exam topics and preparing you for the numerous challenges the exams present.

These official study guides help you master all the topics on the CCNA exams, including:

  • TCP/IP and OSI networking models
  • Operating Cisco routers and LAN switches
  • Ethernet switch configuration and troubleshooting
  • Virtual LANs and Spanning Tree Protocol
  • Wireless LANs
  • IP addressing and subnetting
  • Routing protocols
