Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon FSx for NetApp ONTAP
Options D (Amazon FSx for NetApp ONTAP) and E (Amazon EFS) are correct because they provide NFS-based shared file systems that support the required protocols for SAP transport directory and can be configured for high availability. Option A (Amazon EBS Multi-Attach) is block storage, not a shared file system, and does not support concurrent read/write operations required for SAP. Option B (Amazon S3) is object storage, not POSIX-compliant. Option C (Amazon FSx for Windows File Server) uses SMB protocol, not NFS, which is required by SAP.
