Negative Positive
Title: Cisco CID Certification Guide
Review: I took the exam and did pass it. I was reading this book and was amazed with the errors and the references to graphs and charts that were not in the book. The book goes into a painfull explanation of SNA, which is more confusing then helping the issue. The voice part is readable but that just about it. I would not recommend this book to anyone who want to pass the test. It has too much irrelevant information.
