AWS Certified Solutions Architect – Associate (SAA-C03) — Question 950

A company runs its media rendering application on premises. The company wants to reduce storage costs and has moved all data to Amazon S3. The on-premises rendering application needs low-latency access to storage.

The company needs to design a storage solution for the application. The storage solution must maintain the desired application performance.

Which storage solution will meet these requirements in the MOST cost-effective way?

Answer options

• A. Use Mountpoint for Amazon S3 to access the data in Amazon S3 for the on-premises application.
• B. Configure an Amazon S3 File Gateway to provide storage for the on-premises application.
• C. Copy the data from Amazon S3 to Amazon FSx for Windows File Server. Configure an Amazon FSx File Gateway to provide storage for the on-premises application.
• D. Configure an on-premises file server. Use the Amazon S3 API to connect to S3 storage. Configure the application to access the storage from the on-premises file server.

Correct answer: B

Explanation

Amazon S3 File Gateway is the ideal, cost-effective solution because it caches frequently accessed S3 data locally, providing the on-premises rendering application with the required low-latency access. Mountpoint for Amazon S3 (Option A) is optimized for EC2 instances and not intended for on-premises deployment, while using Amazon FSx (Option C) or setting up a custom local file server (Option D) adds unnecessary administrative overhead and significantly higher storage costs.
