Question #1953
A company operates a hybrid cloud environment with on-premises Microsoft Windows SMB file servers and Linux NFS file servers. They aim to replace their on-premises file servers with a fully managed AWS storage service that supports simultaneous access via both SMB and NFS protocols. The solution must allow shared access to the same dataset across both protocols and provide redundancy within a single Availability Zone. Which solution meets these requirements?
Use Amazon FSx for NetApp ONTAP with multi-protocol access configured.
Deploy two Amazon EC2 instances: one configured as a Windows SMB file server and another as a Linux NFS file server.
Use Amazon FSx for Windows File Server for SMB access and Amazon EFS for NFS access.
Use Amazon S3 with an Amazon S3 File Gateway and Storage Gateway for protocol translation.
Explanation
The correct answer is A because Amazon FSx for NetApp ONTAP is a fully managed service that supports multi-protocol access (SMB and NFS) to the same dataset, enabling seamless shared access across both protocols. It also provides redundancy within a single Availability Zone (AZ) using its built-in high-availability architecture.
Why other options are incorrect:
- B: Deploying EC2 instances requires manual management, lacks native multi-protocol synchronization, and does not guarantee redundancy within a single AZ.
- C: FSx for Windows (SMB) and EFS (NFS) are separate services; they cannot share the same dataset across protocols.
- D: S3 is object storage, not a file system. While Storage Gateway can translate protocols, it does not support simultaneous multi-protocol access to the same dataset.
Key Points:
- FSx for NetApp ONTAP supports multi-protocol access (SMB/NFS) on the same volume.
- Fully managed and AZ-redundant.
- Avoid solutions requiring separate datasets or manual management.
Answer
The correct answer is: A
