This is the 2nd time that I have taken the CISSP exam and failed. I have been in the security field for over 15 years as a security analyst, Security Manager, and IT Security Director. I have been working in IT for over 30+ years. After the first failure I was below proficiency in 3 domains. I took on the attitude that I got knocked down but I am going to get right back up and try again. So this time I purchased the ISC2 online self study course with 100+ videos and went through them twice taking a tremendous amount of notes. I took the domain tests, and the domain exercises. I read the Sybex Official Study Guide 8th edition from front cover to back. I studied the official practice tests 2nd ED and scored 95-100% on all domains. I used the flash cards which came with the online course and knew them all. On my second attempt today I failed even worse than the first time. I cannot talk about the specific questions on the exam but I will say that the questions were so long and confusing it was disappointing. Nothing on OSI, nothing on protocols or the threats at the different levels, nothing on code of ethics, nothing on encryption, nothing on DR, nothing on backups, nothing on SLE & ARO, nothing on OWASP....I could go on. I think it is more about comprehension of the English language and being a good test taker. I have spent over $2K trying to pass this exam and many many hours of dedicated studying. I don't even know how to suggest a study method. This is a money making machine. Very disappointed.
