AWS Certified Solutions Architect – Associate (SAA-C02) — Question 262

A solutions architect must migrate a Windows internet information Services (IIS) web application to AWS. The application currently relies on a file share hosted in the user's on-premises network-attached storage (NAS). The solutions architected has proposed migrating the IIS web servers to Amazon EC2 instances in multiple Availability Zones that are connected to the storage solution, and configuring an Elastic Load Balancer attached to the instances.
Which replacement to the on-premises file share is MOST resilient and durable?

Answer options

• A. Migrate the file Share to Amazon RDS.
• B. Migrate the file Share to AWS Storage Gateway
• C. Migrate the file Share to Amazon FSx for Windows File Server.
• D. Migrate the file share to Amazon Elastic File System (Amazon EFS)

Correct answer: C

Explanation

The correct answer is C, as Amazon FSx for Windows File Server provides a fully managed native Windows file system, which is designed to handle Windows-based applications and offers high durability and availability. Options A and B are not suitable since RDS is for databases and Storage Gateway is primarily for hybrid cloud storage integration, while D, Amazon EFS, is a shared file system that may not offer the same level of compatibility and performance for Windows applications as FSx.
