AWS Certified Solutions Architect – Associate (SAA-C02) — Question 639

A company is migrating to the AWS Cloud. A file server is the first workload to migrate. Users must be able to access the file share using the Server Message
Block (SMB) protocol. Which AWS managed service meets these requirements?

Answer options

• A. Amazon Elastic Block Store (Amazon EBS)
• B. Amazon EC2
• C. Amazon FSx
• D. Amazon S3

Correct answer: C

Explanation

Amazon FSx (specifically Amazon FSx for Windows File Server) provides fully managed file storage that is accessible over the industry-standard Server Message Block (SMB) protocol. Amazon EBS provides block-level storage for EC2 instances rather than managed network file shares, while Amazon S3 is an object storage service that does not natively support SMB. Amazon EC2 is an infrastructure-as-a-service (IaaS) offering and not a fully managed file sharing service.
