AWS Certified Solutions Architect – Associate (SAA-C02) — Question 254

A company is backing up on-premises databases to local file server shares using the SMB protocol. The company requires immediate access to 1 week of backup files to meet recovery objectives. Recovery after a week is less likely to occur, and the company can tolerate a delay in accessing those older backup files.
What should a solutions architect do to meet these requirements with the LEAST operational effort?

Answer options

• A. Deploy Amazon FSx for Windows File Server to create a file system with exposed file shares with sufficient storage to hold all the desired backups.
• B. Deploy an AWS Storage Gateway file gateway with sufficient storage to hold 1 week of backups. Point the backups to SMB shares from the file gateway.
• C. Deploy Amazon Elastic File System (Amazon EFS) to create a file system with exposed NFS shares with sufficient storage to hold all the desired backups.
• D. Continue to back up to the existing file shares. Deploy AWS Database Migration Service (AWS DMS) and define a copy task to copy backup files older than 1 week to Amazon S3, and delete the backup files from the local file store.

Correct answer: B

Explanation

The correct answer, B, is optimal because the AWS Storage Gateway file gateway efficiently integrates with existing SMB shares, allowing immediate access to recent backups while simplifying management. Option A involves more operational overhead by deploying Amazon FSx, while option C does not align with the SMB requirement. Option D adds unnecessary complexity by involving file transfers and deletions from the local store.
