Suggested answer: D

Explanation:

https://docs.aws.amazon.com/cloudhsm/latest/userguide/best-practices.htmlQ: Can other AWS services use CloudHSM to store and manage keys? AWS services integrate with AWS Key Management Service, which in turn is integrated with AWS CloudHSM through the KMS custom key store feature. If you want to use the server-side encryption offered by many AWS services (such as EBS, S3, or Amazon RDS), you can do so by configuring a custom key store in AWS KMS.
