Although it's the first step in the Cisco Career Certifications, the Cisco Certified Network Associate (CCNA) exam is a difficult test. The recent additions of performance-based questions have made it even more challenging. Your first attempt at becoming Cisco certified requires a lot of study and confidence in your networking knowledge. When you're ready to test your skills, complete your knowledge of exam topics, and prepare for exam day, you need the preparation tools found in CISCO CCNA EXAM #640-607 CERTIFICATION GUIDE from Cisco Press. Completely revised by CCIE and Certified Cisco Systems Instructor Wendell Odom, CISCO CCNA EXAM #640-607 CERTIFICATION GUIDE is a comprehensive study tool for the CCNA exam. Updated with new content and features to make it easier to read and reference, this book helps you understand and master the material you will need to know to the exam. The instructor-developed elements and techniques enable you to maximize your retention of exam topics. "Do I Know This Already?" quizzes open each chapter and allow you to decide how much time you need to spend on each section. Exam topic lists and Foundation Summary tables and figures make referencing easy and give you a quick refresher whenever you need it. Challenging chapter-ending review questions and scenario exercises help you assess your knowledge and reinforce key concepts. This edition of the book includes special features in both the text and CD-ROM to help you prepare for the new simulation-based questions you will encounter on the exam. These new simulation-based questions are designed to test your hands-on skills. A chapter of lab scenarios allows you to practice applying your knowledge on home-, work-, or remote access-based labs. In addition to these exercises, the robust exam engine on the CD-ROM helps you assess your testing readiness. The CD-ROM's test engine includes powerful features that enable you to take practice exams, focus on particular topic areas, track your progress, and refer to electronic text to review concepts.
