AWS Certified SysOps Administrator – Associate — Question 171

A company is migrating its production file server to AWS. All data that is stored on the file server must remain accessible if an Availability Zone becomes unavailable or when system maintenance is performed. Users must be able to interact with the file server through the SMB protocol. Users also must have the ability to manage file permissions by using Windows ACLs.

Which solution will meet these requirements?

Answer options

• A. Create a single AWS Storage Gateway file gateway.
• B. Create an Amazon FSx for Windows File Server Multi-AZ file system.
• C. Deploy two AWS Storage Gateway file gateways across two Availability Zones. Configure an Application Load Balancer in front of the file gateways.
• D. Deploy two Amazon FSx for Windows File Server Single-AZ 2 file systems. Configure Microsoft Distributed File System Replication (DFSR).

Correct answer: B

Explanation

The correct solution is B, as Amazon FSx for Windows File Server Multi-AZ provides high availability and supports SMB protocol along with Windows ACLs for file permission management. Option A lacks the Multi-AZ capability needed for fault tolerance. Option C, while having multiple gateways, doesn't meet the requirement for file permission management. Option D's Single-AZ setup does not provide the necessary redundancy during an Availability Zone outage.
