I'm currently using the Official (ISC)2 guide to the CISSP CBK Third edition to study for the CISSP exam. Will this be enough or will I fail by using only this book? I am also noticing after reading the book twice and trying the practice questions on freepracticetests.org there are questions I cannot answer at all because the book just doesn't have an answer for it. Will the exam ask questions outside of the CBK third edition book? Any help will be greatly appreciated. Thanks, p
