AWS Certified Solutions Architect – Associate (SAA-C03) — Question 185

A company has a Windows-based application that must be migrated to AWS. The application requires the use of a shared Windows file system attached to multiple Amazon EC2 Windows instances that are deployed across multiple Availability Zone:

What should a solutions architect do to meet this requirement?

Answer options

• A. Configure AWS Storage Gateway in volume gateway mode. Mount the volume to each Windows instance.
• B. Configure Amazon FSx for Windows File Server. Mount the Amazon FSx file system to each Windows instance.
• C. Configure a file system by using Amazon Elastic File System (Amazon EFS). Mount the EFS file system to each Windows instance.
• D. Configure an Amazon Elastic Block Store (Amazon EBS) volume with the required size. Attach each EC2 instance to the volume. Mount the file system within the volume to each Windows instance.

Correct answer: B

Explanation

The correct answer is B because Amazon FSx for Windows File Server provides a fully managed, shared file system that is compatible with Windows applications and can be accessed by multiple EC2 instances across Availability Zones. Options A and D do not provide a shared file system solution, while option C, Amazon EFS, is optimized for Linux environments and not ideal for Windows-based applications.
