Summary

 The official test preparation guide for the CCDA 640-861 DESGN exam

• Review topics in the CCDA 640-861 DESGN exam for comprehensive exam readiness
• Prepare with proven study tools like foundation summaries, and pre- and post-chapter quizzes to ensure mastery of the subject matter
• Get into test-taking mode with a CD-ROM testing engine containing over 200 questions that measure testing readiness and provide feedback on areas requiring further study

The first step in the Cisco Systems certification networking design track, CCDA (Cisco Certified Design Associate) certification requires that a candidate pass the CCDA 640-861 DESGN exam. CCDAs have the skills needed to determine customer requirements for security, scalability, and network management; design a network structure that meets customers' needs; identify how to build a network prototype; and link Cisco's products in an end-to-end manner.

CCDA Exam Certification Guide (CCDA Self-Study), Second Edition is designed for professional networkers and students who are pursuing CCDA certification. As such, the book will cover all the exam topics upon which candidates will be tested in this new version of the CCDA exam. Each chapter uses all the necessary components to help a reader prepare for the exam, including "Do I Know this Already" quizzes that assess knowledge; Foundation Summary sections that highlight essential concepts; exam topic lists for easy reference; and end-of-chapter review questions. The final chapter in the book contains scenarios that help readers prepare for the exam.

A companion CD-ROM contains more than 200 questions intended to provide testing preparation and feedback on areas for further study.
