AWS Certified Solutions Architect – Associate (SAA-C02) — Question 149

A company wants to replicate its data to AWS to recover in the event of a disaster. Today, a system administrator has scripts that copy data to a NFS share.
Individual backup files need to be accessed with low latency by application administrators to deal with errors in processing.
What should a solutions architect recommend to meet these requirements?

Answer options

• A. Modify the script to copy data to an Amazon S3 bucket instead of the on-premises NFS share.
• B. Modify the script to copy data to an Amazon S3 Glacier Archive instead of the on-premises NFS share.
• C. Modify the script to copy data to an Amazon Elastic File System (Amazon EFS) volume instead of the on-premises NFS share.
• D. Modify the script to copy data to an AWS Storage Gateway for File Gateway virtual appliance instead of the on-premises NFS share.

Correct answer: D

Explanation

The correct answer is D because AWS Storage Gateway for File Gateway allows for low-latency access to files and integrates seamlessly with existing applications, making it ideal for the required access by application administrators. Options A and C, while valid storage solutions, do not provide the same low-latency access to individual files as the File Gateway. Option B is not suitable since Amazon S3 Glacier is designed for archival storage and has higher latency, which does not meet the accessibility requirement.
