Got a good pass yesterday, very happy with the result. Lots on KMS and key rotation, I think the split of questions really followed the course guide. CloudHSM was only mentioned in 1 question as a possible answer. A couple of questions on AD integration, thankfully a heavy Windows background made them easier.
ACG is a good course but I did supplement with extra resources. One thing not mentioned in the course or my exam was relating to KMS and Cloud HSM that KMS is FIPS 140-2 level 2 compliant not level 3. It might be irrelevant but on a mock question that tripped me up.
I also have same question as mprasoon
