CISSP in 21 Days - Second Edition

This book is a brief overview of everything that may appear on the exam, with brief explanations.Pros:Quickly run through, marking unfamiliar subjects to use other study products for.Cons:Uses acronyms way too much. I counted about 34 times IP was used in different context outside of Internet Protocol.There are NO answers to the "sample" questions given at the end of each chapter, nor the mock exam.The "Full Blown Mock Test" that is verbatim on the back of the book, is only 178 questions... not even close to the actual CISSP.This book was suppose to be written in 2016. In the preface, it claims to go over the 8 domains covered. On the back of the book refers to the 10 domains covered. In 2015 the exam switched to 8 domains. Who doesn't check for this. I would of been fine if at LEAST the questions had answers, but this is ridiculous, and clearly this was a rushed out book with minimal updates to the current exam, which by current, is over a year old.
