Which of the following is NOT an AWS storage service?

  1. Amazon S3
  2. Amazon EFS
  3. Amazon RDS ✓
  4. Amazon EBS

Correct answer: Amazon RDS

Option C is correct because Amazon RDS (Relational Database Service) is a managed database service, not a storage service; it provides compute and database engine capabilities on top of underlying storage rather than raw or object storage. Option A is wrong because Amazon S3 is a core AWS object storage service. Option B is wrong because Amazon EFS (Elastic File System) is a managed network file storage service. Option D is wrong because Amazon EBS (Elastic Block Store) is a block storage service used primarily with EC2 instances.
