Which services are integrated with KMS encryption?

KMS, or AWS Key Management Service, provides encryption capabilities for various AWS services, enabling you to manage cryptographic keys securely. When looking at the integration of KMS with specific services for encryption purposes, Amazon RDS (Relational Database Service) and Amazon EBS (Elastic Block Store) are prominently supported.

Both Amazon RDS and Amazon EBS can leverage KMS to encrypt data at rest and in transit. With Amazon RDS, KMS enables the encryption of database instances and snapshots. This ensures that sensitive data stored in the database remains protected from unauthorized access. For Amazon EBS, KMS supports encryption of volumes, protecting the data being stored on the disks. This integration provides an added layer of security essential for compliance with various regulations.

The other services mentioned, while they do have security features, are not as directly associated with KMS encryption in the same way. For instance, while Amazon EC2 can use EBS volumes that are encrypted with KMS, the integration is not as direct as the dedicated encryption capabilities offered for RDS and EBS. Therefore, D is the correct choice, highlighting the specific and straightforward integration of KMS with RDS and EBS for encryption purposes.
