AWS Certified Solutions Architect – Associate (SAA-C03) — Question 214

A medical research lab produces data that is related to a new study. The lab wants to make the data available with minimum latency to clinics across the country for their on-premises, file-based applications. The data files are stored in an Amazon S3 bucket that has read-only permissions for each clinic.

What should a solutions architect recommend to meet these requirements?

Answer options

• A. Deploy an AWS Storage Gateway file gateway as a virtual machine (VM) on premises at each clinic
• B. Migrate the files to each clinic’s on-premises applications by using AWS DataSync for processing.
• C. Deploy an AWS Storage Gateway volume gateway as a virtual machine (VM) on premises at each clinic.
• D. Attach an Amazon Elastic File System (Amazon EFS) file system to each clinic’s on-premises servers.

Correct answer: A

Explanation

The correct answer is A because deploying an AWS Storage Gateway file gateway allows clinics to access S3 data with low latency as if it were local files. Option B is incorrect since migrating files can introduce delays and is not necessary for real-time access. Option C is wrong because a volume gateway is not optimized for file access, and option D is not suitable as EFS is not designed for direct on-premises integration without additional services.
