Exam AWS Certified SAP on AWS - Specialty PAS-C01 topic 1 question 126 discussion

Exam question from Amazon's AWS Certified SAP on AWS - Specialty PAS-C01
Question #: 126
Topic #: 1
[All AWS Certified SAP on AWS - Specialty PAS-C01 Questions]

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?

  • 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.

Pilot light meets both RPO and RTO requirements most cost effectively. So answer is A. https://docs.aws.amazon.com/wellarchitected/latest/reliability-pillar/rel_planning_for_recovery_disaster_recovery.html

Should be A. B provides similar solution but more expensive that A. C the secondary standby in the primary region probably cannot handle the load due to the smaller instance size. D it is going to take ages to restore those backup, that is provided that the backup is taken and replicated as per the RPO. In short D is completely insane.

Selected Answer: C
C would be the best regarding the costs, just switch the instance type to bigger before taking over.
