AWS Certified Solutions Architect – Associate (SAA-C03) — Question 338

A company has an aging network-attached storage (NAS) array in its data center. The NAS array presents SMB shares and NFS shares to client workstations. The company does not want to purchase a new NAS array. The company also does not want to incur the cost of renewing the NAS array’s support contract. Some of the data is accessed frequently, but much of the data is inactive.

A solutions architect needs to implement a solution that migrates the data to Amazon S3, uses S3 Lifecycle policies, and maintains the same look and feel for the client workstations. The solutions architect has identified AWS Storage Gateway as part of the solution.

Which type of storage gateway should the solutions architect provision to meet these requirements?

Answer options

Correct answer: D

Explanation

Amazon S3 File Gateway provides NFS and SMB access to data stored directly in Amazon S3, making it the perfect replacement for the legacy NAS while maintaining the same user experience and enabling S3 Lifecycle policies. Volume Gateway and Tape Gateway are block- and tape-based solutions that do not natively present SMB/NFS file shares directly to S3. Amazon FSx File Gateway is designed specifically for accessing Amazon FSx for Windows File Server, rather than direct Amazon S3 buckets with custom S3 Lifecycle policies.
