AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 4

A data analysis company has two SAP landscapes that consist of sandbox, development, QA, pre-production, and production servers. One landscape is on Windows, and the other landscape is on Red Hat Enterprise Linux. The servers reside in a room in a building that other tenants share.
An SAP solutions architect proposes to migrate the SAP applications to AWS. The SAP solutions architect wants to move the production backups to AWS and wants to make the backups highly available to restore in case of unavailability of an on-premises server.
Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Take a backup of the production servers. Implement an AWS Storage Gateway Volume Gateway. Create file shares by using the Storage Gateway Volume Gateway. Copy the backup files to the file shares through NFS and SMB.
• B. Take a backup of the production servers. Send those backups to tape drives. Implement an AWS Storage Gateway Tape Gateway. Send the backups to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) through the S3 console. Move the backups immediately to S3 Glacier Deep Archive.
• C. Implement a third-party tool to take images of the SAP application servers and database server. Take regular snapshots at 1-hour intervals. Send the snapshots to Amazon S3 Glacier directly through the S3 Glacier console. Store the same images in different S3 buckets in different AWS Regions.
• D. Take a backup of the production servers. Implement an Amazon S3 File Gateway. Create file shares by using the S3 File Gateway. Copy the backup files to the file shares through NFS and SMB. Map backup files directly to Amazon S3. Configure an S3 Lifecycle policy to send the backup files to S3 Glacier based on the company’s data retention policy.

Correct answer: D

Explanation

Option D is the most cost-effective solution as it allows for efficient backup management and utilizes S3's lifecycle policies to minimize storage costs by transitioning files to S3 Glacier based on retention needs. Options A and C do not provide the same level of cost-effectiveness through lifecycle management, and Option B involves additional costs with tape storage and less efficient access methods.
