Try crafting a security questionnaire around SAAS, PAAS and IAAS that will get you thinking. You will be turning over stones and finding new things to ask every time. Also, discover what CASB's can do and then the juices will really start flowing. Like many of the other posters I also turned to the Sybex book for reference.
This post was extremely helpful. I've already DL the resources. Thank you for your post!
I have not taken CCSP, but CISSP. There are many practice sites on the web and your first port of call is the advice provided by the ISC2 website itself. The exam questions are not shared in order to keep them safe from abuse. Most exam sites are "questions in the form of ....". As a tool to practice exam technique, they have value, but the best preparation is to know the syllabus and the course material in my opinion ... and to have the experience to apply what you have learned.
In my experience and please note that I took the CCSP about one year age there were very little practice questions other than the material supplied from The Training Camp. In the past I have always used Transcender practice tests for CISSP, MCSE, CISCO, etc. but Transcender did not offer any practice tests for CCSP.
