A. Avoiding user disruption if a regional failure occurs means you need to pick a multi-region service. That rules out C and D. Having more control over the EKs means CMEK. That eliminates B.

Selected Answer: A
A for me: it's A or C because we want to control keys, but C would cause downtime, since we would need to manually failover to another region if a regional failure occurs, and we don't want that.

Yes default encryption comes with AES-256 but the question states that you need to control where you store the encryption keys. that can be achieved by CMEK.
