Correct answer & explanation
✓
Amazon EFS
Amazon EFS provides a scalable NFS file system that can be shared across multiple EC2 instances, making it suitable for SAP transport directories. Option A is wrong because Amazon FSx for Windows File Server uses SMB protocol, not NFS. Option B is wrong because Amazon S3 is object storage, not a file system. Option C is wrong because Amazon EBS is block storage attached to a single instance and cannot be shared across multiple instances natively.
