AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 96

A company is migrating its SAP S/4HANA landscape from on premises to AWS. An SAP solutions architect is designing a backup solution for the SAP S/4HANA landscape on AWS. The backup solution will use AWS Backint Agent for SAP HANA (AWS Backint agent) to store backups in Amazon S3.

The company's backup policy for source systems requires a retention period of 150 days for weekly full online backups. The backup policy requires a retention period of 30 days for daily transaction log backups. The company must keep the same backup policy on AWS while maximizing data resiliency. The company needs the ability to retrieve the backup data one or two times each year within 10 hours of the retrieval request.

The SAP solutions architect must configure AWS Backint agent and S3 Lifecycle rules according to these parameters.

Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Configure the target S3 bucket to use S3 Glacier Deep Archive for the backup files. Create S3 Lifecycle rules on the S3 bucket to delete full online backup files that are older than 150 days and to delete log backup files that are older than 30 days.
• B. Configure the target S3 bucket to use S3 Standard storage for the backup files. Create an S3 Lifecycle rule on the S3 bucket to move all the backup files to S3 Glacier Instant Retrieval. Create additional S3 Lifecycle rules to delete full online backup files that are older than 150 days and to delete log backup files that are older than 30 days.
• C. Configure the target S3 bucket to use S3 One Zone-Infrequent Access (S3 One Zone-IA) for the backup files. Create S3 Lifecycle rules on the S3 bucket to move full online backup files that are older than 30 days to S3 Glacier Flexible Retrieval and to delete log backup files that are older than 30 days. Create an additional S3 Lifecycle rule to delete full online backup files that are older than 150 days.
• D. Configure the target S3 bucket to use S3 Standard-Infrequent Access (S3 Standard-IA) for the backup files. Create S3 Lifecycle rules on the S3 bucket to move full online backup files that are older than 30 days to S3 Glacier Flexible Retrieval and to delete log backup files that are older than 30 days. Create an additional S3 Lifecycle rule to delete full online backup files that are older than 150 days.

Correct answer: D

Explanation

Option D is the most cost-effective solution as it uses S3 Standard-Infrequent Access, which is suitable for backups accessed infrequently, while still meeting the retention requirements. Other options either use more expensive storage classes, like S3 Glacier Deep Archive or S3 Standard, or do not efficiently manage the retention policies, making them less cost-effective.
