AWS Certified Solutions Architect – Associate (SAA-C02) — Question 201

A company has a build server that is in an Auto Scaling group and often has multiple Linux instances running. The build server requires consistent and mountable shared NFS storage for jobs and configurations.
Which storage option should a solutions architect recommend?

Answer options

• A. Amazon S3
• B. Amazon FSx
• C. Amazon Elastic Block Store (Amazon EBS)
• D. Amazon Elastic File System (Amazon EFS)

Correct answer: D

Explanation

The correct answer is D, Amazon Elastic File System (Amazon EFS), as it provides a scalable and shared NFS storage solution that can be mounted across multiple instances, making it ideal for the build server's needs. Option A, Amazon S3, is an object storage service that does not support NFS. Option B, Amazon FSx, is designed for Windows file systems, and Option C, Amazon EBS, offers block storage which cannot be shared across multiple instances simultaneously.
