This book is painfully incomplete and inaccurate. I don't believe the author has ever seen the actual exam. I went throught the book with disappointment after every chapter, hoping that maybe the next one will contain useful material, but no. It is true that the book was supposed to cover the previous version of the exam, but the new exam doesn't expand on existing individual topics like HTTP of SSL (just to pick some), only adds new topics.The book can be used as an introduction to the actual study for the exam, but nothing more. I can't believe Cisco is recommending is as an official study guide.
