A
Amazon Elastic Block Store (Amazon EBS)
B
Amazon S3
C
Amazon ElastiCache
D
Amazon Elastic File System (Amazon EFS)
Explanation:
Amazon Elastic File System (Amazon EFS) is the correct choice because:
-
Amazon EFS provides a scalable, fully managed elastic NFS file system that can be mounted by both AWS Cloud resources and on-premises systems
-
It supports cross-environment access through AWS Direct Connect or VPN connections
-
Amazon EBS is block storage that can only be attached to EC2 instances within the same Availability Zone
-
Amazon S3 is object storage, not a file system, and doesn't provide the same file system semantics
-
Amazon ElastiCache is an in-memory caching service, not a file system
EFS is specifically designed for use cases requiring shared file storage across multiple compute instances and environments, making it ideal for hybrid cloud scenarios.
