SAP-C03 practice question: Storage performance and caching (EBS, EFS, FSx, ElastiCache, DAX)

Last verified against current AWS documentation ·How we write our questions

A car maker's engineering group keeps its design files on shared storage. About 800 Windows engineers reach the files over SMB with Active Directory permissions, and a farm of Linux render nodes must read the same files over NFS.

The group needs snapshots so engineers can recover earlier file versions, and it needs the storage to survive the loss of one Availability Zone. The IT team wants a managed service that does not require a file server to be patched.

Which solution meets these requirements?

Choose one answer.

  1. A. Create an Amazon FSx for NetApp ONTAP file system deployed across two Availability Zones, join it to AWS Managed Microsoft AD for SMB access, and mount the same volumes over NFS on the render nodes.
  2. B. Create an Amazon FSx for Windows File Server file system deployed across two Availability Zones, join it to AWS Managed Microsoft AD, and turn on shadow copies so engineers can restore earlier versions.
  3. C. Create an Amazon EFS file system with mount targets in each Availability Zone, and mount it on the render nodes and on the Windows engineers' workstations.
  4. D. Attach Amazon EBS io2 volumes with Multi-Attach to a pair of Linux file servers in one Availability Zone, and export the volumes to both groups of clients.
Show the answer and explanation

Answer: A

  • A. Right: Correct. FSx for NetApp ONTAP serves the same volumes over SMB with Active Directory permissions and over NFS, and it supports snapshots and Multi-AZ deployment. AWS runs the file system, so no file server needs patching.
  • B. Wrong: FSx for Windows File Server serves SMB and supports snapshots and Multi-AZ, but it does not offer NFS for the Linux render nodes. The render farm would have no access path.
  • C. Wrong: EFS serves NFS to Linux clients and does not offer SMB with Active Directory permissions. The Windows engineers would not get the access model they use today.
  • D. Wrong: Multi-Attach volumes are block devices that need a cluster-aware file system, and they live in one Availability Zone. The design also means managing the file servers, which the IT team wants to avoid.

Explanation

ONTAP is the FSx option that serves both SMB and NFS from one managed, Multi-AZ file system with snapshots. Windows File Server lacks NFS, EFS lacks SMB with Active Directory permissions, and EBS block volumes need a file server layer.
