Passed the CCSP

I passed the CCSP - Studied for two months

Books used:
CCSP AIO - Read this a new times to understand the concepts
CCSP (ISC)2 Certified Cloud Security Professional Official Study Guide - Skims through the entire material - I wasn't impressed (Thanks Safari!)
Official Study Guide - Boring read but essential

You need to understand the depth of the material, knowing concepts of REST/SOAP and SAML is not sufficient, you need to know why you would use one instead of the other in real life scenarios,

As mentioned earlier by another member, you should have hands on experience from the management side of things when it comes to cloud computing.

CISSP,PMP,CISA,CISM and now CCSP done in the last 4 years, looking towards new challenges . Best of luck to all.
