Some of the questions contained in this book seem to come from other sources.

I also found that the questions were unclear, poorly phrased, and contained discrepancies.

There is some merit in reviewing this book before testing, but you would think that with all the contributors (9 being CISSPs), that the answers on the sample exam would be correct. Two of the first 100 questions (#67 and #97) of the sample exam are wrong and a handful of others were borderline. Even though they may have quoted other sources, being a CISSP, the authors should have known difference.

While studing for the CISSP exam, my time is best used for absorbing facts, not proofreading. I did not finish the sample exam for fear of committing errors to memory (my protection domain).

However, in all fairness, the questions segmented by domain appear to be of better quaility.

Full Disclosure: I've worked with all of the contributing authors of this book and consider them friends of mine. I also consider each of them consummate professionals who truly know their stuff.

This book is NOT for those who are just beginning their study for the CISSP exam. It IS for those who are nearly ready to take the exam and simply need to ensure that they have a complete understanding of the 10 domains and the types of questions likely to be on the exam. (One reviewer states that some of the questions are unclear... well, *perhaps* that is true, but then again so are the questions on the actual exam. The purpose of this book is to prepare you for that exam and I believe it closely mirrors what you are likely to see when you sit for the CISSP test... therefore, the book accomplishes it's goal very well indeed.)

This book does not replace books such as Shon Harris' excellent "CISSP All-In-One Exam Guide". Nor does it try to do so. Nor should it. Shon's book is excellent for those who need full disclosure of all of the information covered in the ten domains... those who are just beginning their CISSP study. This book is more of of a polisher for those who already know most of the material and just need to find (and plug) knowledge gaps... and for that purpose, it is nothing short of outstanding!

In short, I highly recommend this book. It is not for everyone and most will need to work up to it. But if your almost ready to take the CISSP exam, then you should definately go through the questions in this book first.
