AWS Certified Solutions Architect – Associate (SAA-C02) — Question 363

A company has an on-premises business application that generates hundreds of files each day. These files are stored on an SMB file share and require a low- latency connection to the application servers. A new company policy states all application-generated files must be copied to AWS. There is already a VPN connection to AWS.
The application development team does not have time to make the necessary code modifications to move the application to AWS.
Which service should a solutions architect recommend to allow the application to copy files to AWS?

Answer options

Correct answer: D

Explanation

AWS Storage Gateway (specifically File Gateway) seamlessly integrates with on-premises SMB file shares, providing a local cache for low-latency access while automatically copying files to Amazon S3 without requiring application code changes. Amazon EFS and Amazon FSx for Windows File Server are cloud-based file systems that do not natively provide on-premises caching to ensure low latency. AWS Snowball is designed for physical, offline bulk data transfers rather than continuous daily file ingestion.
