AWS Certified Solutions Architect – Associate (SAA-C02) — Question 282

A company uses on-premises servers to host its applications. The company is running out of storage capacity. The applications use both block storage and NFS storage. The company needs a high-performing solution that supports local caching without re-architecting its existing applications.
Which combination of actions should a solutions architect take to meet these requirements? (Choose two.)

Answer options

• A. Mount Amazon S3 as a file system to the on-premises servers.
• B. Deploy an AWS Storage Gateway file gateway to replace NFS storage.
• C. Deploy AWS Snowball Edge to provision NFS mounts to on-premises servers.
• D. Deploy an AWS Storage Gateway volume gateway to replace the block storage.
• E. Deploy Amazon Elastic Fife System (Amazon EFS) volumes and mount them to on-premises servers.

Correct answer: B, D

Explanation

AWS Storage Gateway is designed to bridge on-premises environments with AWS cloud storage by providing local caching for low-latency access. Deploying a file gateway allows the organization to replace their existing NFS storage seamlessly, while deploying a volume gateway provides block storage via iSCSI to replace their local block storage. Other options like mounting S3 directly or using Amazon EFS do not provide the necessary local caching performance for on-premises servers, and AWS Snowball Edge is not intended for this type of continuous storage integration.
