AWS Certified Solutions Architect – Associate (SAA-C03) — Question 274

A company that primarily runs its application servers on premises has decided to migrate to AWS. The company wants to minimize its need to scale its Internet Small Computer Systems Interface (iSCSI) storage on premises. The company wants only its recently accessed data to remain stored locally.

Which AWS solution should the company use to meet these requirements?

Answer options

Correct answer: D

Explanation

AWS Storage Gateway Volume Gateway cached volumes allow you to store your primary data in Amazon S3 while keeping a cache of recently accessed data locally, which minimizes the need to scale on-premises iSCSI storage. In contrast, stored volumes retain the entire dataset locally on-premises, which does not reduce local storage requirements. Amazon S3 File Gateway provides file-level access (NFS/SMB) rather than block-level iSCSI volumes, and Tape Gateway is designed for virtual tape backup archiving.
