I took the (new) ISSMP test yesterday with additional domain (and no updated studying materials offered from ISC2). I knew the CBK book back and forth and took a boot camp. Fail. I've already passed two ISC2 certs first time so I am really disappointed in ISC2 who, I believe, set me up for failure on this. I hardly recognized any questions. This was an act of futility. A total waste of time I can recommend for no one until proper study materials are available.
When a potential candidate asks if they will be able to pass the updated test without new study materials ISC2 states:
(ISC)² exams are experience-based that include experience-based questions that cannot be learned by studying alone. If you already have the experience in the domains covered in CISSP-ISSMP and believe that you have sufficiently studied those domains, you should feel confident that you are qualified to take the new exam and pass it. (ISC)² cannot guarantee you will pass the exam.
Not in my experience. They also state, "The Official (ISC)² CISSP-ISSMP Training Course (online self-paced) will be available May 15, 2018". The official ISSMP ISC2 online training is still unavailable.
