The best just keeps getting better! Cisco recently refreshed their CCNA exam (#640-607) and added new questions, including simulation and drag-and-drop formats along with the standard multiple-choice variety. The objectives, however, remain the same. Sybex and the world renowned Cisco authority, Todd Lammle, have taken this opportunity to enhance the best-selling CCNA: Cisco Certified Network Associate Study Guide, producing a 3rd edition with the aim of giving CCNA candidates the knowledge and hands-on skills they need for the challenging new exam. Building on the rock-solid instructional content found in previous editions, we've added Real-World Scenarios and Exam Essentials sections to the text to give you the "whys" and "whens" as well as the "hows." And in addition to the advanced testing engine with sample simulation questions, five bonus exams, electronic flashcards, and PDF version of the book found on the CD, we've added a Router Fundamentals Simulator that allows you to practice using key Cisco IOS commands on a virtual router configuration screen. With all the information and study tools included in this new edition at your disposal, you'll be well on your way to attaining your CCNA.
