Ebook: CCNA Cisco Certified Network Associate Study Guide (Exam 640-507), Second Edition

I recently took and passed my CCNA, with little help from this book. Had I only studied this book, I do not think I would have passed. After reading and studying this book for a month, I was given a Cisco Press book, and I found I didn't know half of what I needed to. There are MANY things missing from this book, and they are constantly contradicting themselves. Very poor quality book. If you're studying for a Cisco test, buy a Cisco Press product. The Cisco Press book was much more clearly written, and there were few times in reading it that I was confused.
