Amazon Elastic File System (Amazon EFS)
Managed elastic file storage accessible through supported NFS clients and integrations.
Key points

- No numbered DVA-C02 skill requires file-system administration depth.
Best-known use cases
- Shared file data for approved EC2, container, or Lambda application patterns.
What candidates often confuse it with
- EFS provides shared file storage; EBS provides block volumes; S3 provides object storage APIs.
Key takeaway
Recognize EFS as shared file storage and keep file-system and network administration out of scope.
