1 This is the CCNA book to buy!
This is the best CCNA book to buy for the exam. It is written by serveral industry experts who actually work on Cisco networks. The exam watch in the book is very helpfull.
The questions in this book are realistic to the actuall exam.
The section on bridging and switching is excellant.
2 Truly Awful!
I read Lammle's book (from Sybex) first and planned on reading this book for a review. But, after about the second chapter I gave up because of all the errors I had found. Save your money and buy something from Cisco Press or Sybex (esp. Todd Lammle).
3 Worst 20 bucks spent
Many errors in this book. Some are spelling (annoying), some are wrong answers. I bought this book a week before taking the test, half way through it I had to put it down and go back to Lammle. I guess one way this book helps is you can test your knowledge by spotting their mistakes.
4 pass the test
It is a very good book to preparate for the exam. I come from the Netherlands, and I must take the exam in Englisch. The examwatch in this book is very helpfull. From the internet you have the right to download a full exam and you get a full study book webbased for free. The questions in this book are very hard, but I like it because I thought that the exam was harder then it was. I passed the exam with 903 points.
