yes you are right. I also read the same books that you mentioned. In fact I did not read the All in One guide.I just read the official study guide and the CBK and the official question bank.
I'm preparing as well and find the ISC2 Official Study Guide is written very well and I notice the layout reinforces the domain concepts as you progress thru each chapter; included are summaries, tips, labs, etc. Do you really feel you needed to read "The Official (ISC)2 Guide to the CCSP CBK?"
I think you mentioned you were already a CISSP. I am too. I'm a week out from my exam date and will be going through CCSP® Official (ISC)2® Practice Tests by Ben Malisow all week. I also do security risk assessments for Cloud Vendors for my company. What do you think? Any other suggestions?
I did not complete CISSP. Now I am preparing for the CCSP Certfification. Currently i am working on Unix Shell scripting technology and trying to move towards security end. Till now i did not complete and prepare any security certifications.
