Just knocked out this beast a few hours ago. I feel I was able to pass relying heavily on years of Info Sec experience which includes the other eight certifications that I've done since 2015 (there is a lot of overlap after a while). It took a little over two months to prepare using the following resources:
CCSP (ISC)2 Certified Cloud Security Professional Official Study Guide
Official (ISC)2 Guide to the CCSP CBK
CCSP Official (ISC)2 Practice Tests
Good luck to anyone else pursuing this.
Next up - more language studies. I'll take a break on certs until 2020.
