Title: Very good but not enough
Review: I use this book as my major study guide, and use the Exam Notes for revision. This book starts from fundamental things, so that it can refresh you about some things basic, you can go on studying easier. I think you can get what you want and what you need in CCNA exam from this book. However, this book cannot give a full details about WAN, such as Frame Relay, ISDN etc. I think you need other resources for supplement to ensure you can pass.Anyway, it is still worth to buy it. I can get 860 with this book and Exam Notes
