An enterprise is migrating a legacy monolithic application to AWS. The application uses a proprietary file system and requires sub-millisecond latency to shared storage. The application runs on Windows Server and cannot be refactored. The architecture must support high availability across multiple Availability Zones. Which storage solution meets these requirements?

Answer options:

Amazon FSx for Windows File Server configured with a Multi-AZ deployment.

Amazon Elastic File System (EFS) mounted on the Windows instances using the NFS protocol.

Amazon EBS Provisioned IOPS (io2) volumes attached to multiple EC2 instances using Multi-Attach.

AWS Storage Gateway File Gateway backed by Amazon S3.

How to approach this question

Identify the AWS managed storage service designed specifically for Windows workloads requiring shared file storage.
