AWS Certified Solutions Architect – Associate (SAA-C03) — Question 33

A company has more than 5 TB of file data on Windows file servers that run on premises. Users and applications interact with the data each day.
The company is moving its Windows workloads to AWS. As the company continues this process, the company requires access to AWS and on-premises file storage with minimum latency. The company needs a solution that minimizes operational overhead and requires no significant changes to the existing file access patterns. The company uses an AWS Site-to-Site VPN connection for connectivity to AWS.
What should a solutions architect do to meet these requirements?

Answer options

• A. Deploy and configure Amazon FSx for Windows File Server on AWS. Move the on-premises file data to FSx for Windows File Server. Reconfigure the workloads to use FSx for Windows File Server on AWS.

Configure the cloud workloads to use FSx for Windows File Server on AWS. Configure the on-premises workloads to use the FSx File Gateway.

Correct answer: D

Explanation

The correct answer is D because it allows seamless integration between on-premises and AWS environments by using both Amazon FSx for Windows File Server and an FSx File Gateway. This configuration minimizes latency and operational overhead while supporting existing file access patterns. Options A, B, and C either require significant changes to workloads or do not provide the optimal solution for maintaining low latency and operational efficiency.
