AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 116

A company wants to implement a highly available SAP S/4HANA workload on AWS with automatic failover. The company also needs a cross-Region disaster recovery (DR) solution for the SAP S/4HANA production system. The company has a required RPO of up to 15 minutes and a required RTO of up to 120 minutes for the DR solution.

Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Deploy two identically sized SAP S/4HANA systems, each in a different Availability Zone in the primary AWS Region. Set up synchronous SAP HANA system replication with preload between the systems. Set up a pilot light DR system with asynchronous SAP HANA system replication without preload to the secondary Region.
• B. Deploy two identically sized SAP S/4HANA systems, each in a different Availability Zone in the primary AWS Region. Set up synchronous SAP HANA system replication with preload between the systems. Set up a full-size DR system with asynchronous SAP HANA system replication without preload to the secondary Region.
• C. Deploy two SAP S/4HANA systems, each in a different Availability Zone in the primary AWS Region. Use a smaller size for the secondary system. Set up synchronous SAP HANA system replication without preload between the systems. Set up a pilot light DR system with asynchronous SAP HANA system replication to the secondary Region.
• D. Deploy two identically sized SAP S/4HANA systems, each in a different Availability Zone in the primary AWS Region. Set up synchronous SAP HANA system replication with preload between the systems. For DR, set up S3 Cross-Region Replication (CRR) for SAP HANA backup files from the primary Region to the secondary Region.

Correct answer: A

Explanation

Option A is the most cost-effective solution as it utilizes a pilot light DR system, which saves costs while meeting the required RPO and RTO. Options B and C are more expensive due to their full-size DR system and additional resource requirements. Option D, while effective, does not provide the same level of immediate failover capability as option A.
