Hi venom77. After reading your post I went to check my copy of this book. I still have my answers marked in pencil at the back of the book and my answers all correspond with yours. I also noticed these mistakes while studying for the exam but never got round to posting anything about them.
Another thing that really irritated me about this book was the ExamGear test engine included on the CD which accompanies the book. The exam asks no questions at all about chapter 11 (Buffer Overflows, Viruses and Worms). I compensated for this by re-reading that particular chapter many times and re-doing the printed questions at the end of the chapter. The exam also seemed to have only one pool of 125 questions, so after you've done it once, the questions repeat themselves. I even tried to log on to the exam prep web site to download updates for the exam (as the book itself reccomends) but none were available.
