AWS Certified Solutions Architect – Professional (SAP-C02) — Question 395

A company wants to design a disaster recovery (DR) solution for an application that runs in the company’s data center. The application writes to an SMB file share and creates a copy on a second file share. Both file shares are in the data center. The application uses two types of files: metadata files and image files.

The company wants to store the copy on AWS. The company needs the ability to use SMB to access the data from either the data center or AWS if a disaster occurs. The copy of the data is rarely accessed but must be available within 5 minutes.

Answer options

• A. Deploy AWS Outposts with Amazon S3 storage. Configure a Windows Amazon EC2 instance on Outposts as a file server.
• B. Deploy an Amazon FSx File Gateway. Configure an Amazon FSx for Windows File Server Multi-AZ file system that uses SSD storage.
• C. Deploy an Amazon S3 File Gateway. Configure the S3 File Gateway to use Amazon S3 Standard-Infrequent Access (S3 Standard-IA) for the metadata files and to use S3 Glacier Deep Archive for the image files.
• D. Deploy an Amazon S3 File Gateway. Configure the S3 File Gateway to use Amazon S3 Standard-Infrequent Access (S3 Standard-IA) for the metadata files and image files.

Correct answer: D

Explanation

Amazon S3 File Gateway supports SMB access and allows storing data directly in Amazon S3 buckets. S3 Standard-Infrequent Access (S3 Standard-IA) is ideal for rarely accessed data while providing rapid retrieval times (milliseconds), well within the 5-minute requirement. S3 Glacier Deep Archive is incorrect because its minimum retrieval time is 12 hours, which fails to meet the 5-minute recovery target.
