Question
A company wants to migrate its SAP S/4HANA infrastructure to AWS. The infrastructure includes production, pre-production, test, and development environments. The pre-production environment is an identical copy of the production environment. The production system must comply with a new policy that requires the landscape to be able to fail over to a secondary AWS Region. The required RPO is 5 minutes. The required RTO is 4 hours. The estimated SAP HANA database size is 6 TB. Which solution will meet these requirements MOST cost-effectively?

Explanation
The most cost-effective DR strategy leverages the pre-production environment, which is already an identical copy of production. By deploying the pre-production system in a secondary AWS Region and replicating the SAP HANA database to it using HANA System Replication (HSR) in asynchronous mode, the RPO of 5 minutes is achievable. The RTO of 4 hours is met by promoting the pre-production system to production during a failover. This avoids the cost of maintaining a dedicated, idle 6 TB DR instance. Options C and D describe dedicated 6 TB DR sites, which are more expensive. Option B describes a 500 GB DR site, which is insufficient for a 6 TB HANA database and would not meet RPO/RTO requirements.
