Ebook: CCDA Official Exam Certification Guide (Exam 640-863)

This book does a good job of providing the baseline information required for the CCDA exam. There is a lot of excellent information and reference in this book that can be used in everyday work with network design and pre-sales activity. While I found this book to be very helpful in preparing for the CCDA exam do not use this book as your only material in preparation for the exam.
