Which solution will meet these requirements?
Create a single AWS Storage Gateway file gateway.
Create an Amazon FSx for Windows File Server Multi-AZ file system.
Deploy two AWS Storage Gateway file gateways across two Availability Zones. Configure an Application Load Balancer in front of the file gateways.
Deploy two Amazon FSx for Windows File Server Single-AZ 2 file systems. Configure Microsoft Distributed File System Replication (DFSR).
Explanations:
AWS Storage Gateway file gateway does not provide high availability across multiple Availability Zones, and it doesn’t support SMB protocol with the required Windows ACLs.
Amazon FSx for Windows File Server Multi-AZ provides high availability across multiple Availability Zones, supports SMB, and allows users to manage file permissions with Windows ACLs.
Deploying two Storage Gateway file gateways with an Application Load Balancer does not ensure high availability across AZs, and it does not support Windows ACLs.
Two single-AZ FSx file systems with DFSR do not provide automatic high availability across Availability Zones, and DFSR requires manual setup and is not ideal for real-time synchronization.
