I bought this book not 2 months ago. I have a CCNA sertificate from a course I did about 2 years ago. I read the book cover to cover, then highlighted the 642-436 topics. I then read those topics about three times, did all the questions at the end of the chapters the same amount of times and got a perfect score when taking the simulated exam that comes with the book.
I did the real sertification exam today and failed miserably.
This book does not cover the topics for the 642-436 exam from the right angle AT ALL. The questions in the real exam was about 90% about configuring gateways, UBE's and PBX-to-PBX over WAN implementations.
F.eks This book has three centenses that covers the PBX-to-PBX over WAN implementation. The test had three questions that demanded advanced knowledge about configuring PBX-to-PBX over WAN implementation.
If you want to pass the 642-436 exam, DO NOT buy this book.
