AWS Certified Solutions Architect – Associate (SAA-C02) — Question 4

A company is migrating from an on-premises infrastructure to the AWS Cloud. One of the company's applications stores files on a Windows file server farm that uses Distributed File System Replication (DFSR) to keep data in sync. A solutions architect needs to replace the file server farm.
Which service should the solutions architect use?

Answer options

• A. Amazon EFS
• B. Amazon FSx
• C. Amazon S3
• D. AWS Storage Gateway

Correct answer: B

Explanation

Amazon FSx is designed for Windows-based applications and supports SMB file shares, making it suitable for replacing Windows file server farms that use DFSR. Amazon EFS is more suited for Linux workloads, Amazon S3 is an object storage service with different use cases, and AWS Storage Gateway is primarily for hybrid cloud storage solutions, not a direct replacement for Windows file servers.
