A global company is planning to migrate its SAP S/4HANA workloads and SAP BW/4HANA workloads to AWS. The company’s database will not grow more than 3 TB for the next 3 years. The company's production SAP HANA system has been designed for high availability (HA) and disaster recovery (DR) with the following configurations:
•	HA: SAP HANA system replication configured with SYNC mode and LOGREPLAY operation mode across two Availability Zones with the same size SAP HANA node
•	DR: SAP HANA system replication configured with ASYNC mode and LOGREPLAY operation mode across AWS Regions with the same size SAP HANA node
All the SAP HANA nodes in the current configuration are the same size. For HA, the company wants an RPO of 0 and an RTO of 5 minutes. For DR, the company wants an RPO of 0 and an RTO of 3 hours.
How should the company design this solution to meet the RPO and RTO requirements MOST cost-effectively?

A. Maintain HA with SAP HANA system replication configured with SYNC mode and table preload turned on across two Availability Zones. In each Availability Zone, use the same size SAP HANA node. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with ASYNC mode and table preload turned on. Increase the size of the DR node during a DR event.

B. Maintain HA with SAP HANA system replication configured with SYNC mode and table preload turned on across two Availability Zones. In each Availability Zone, use the same size SAP HANA node. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with ASYNC mode and table preload turned off. Increase the size of the DR node during a DR event.

C. Maintain HA with SAP HANA system replication across two Availability Zones. Decrease the size of the HA secondary node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with SYNC mode and table preload turned on. Increase the size of the HA secondary node during an HA event. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with table preload turned on. Increase the size of the DR node during a DR event.

D. Maintain HA with SAP HANA system replication across two Availability Zones. Decrease the size of the HA secondary node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with SYNC mode and table preload turned on. Increase the size of the HA secondary node during an HA event. Decrease the size of the DR node to at least 64 GiB of memory or the row store size plus 20 GiB, whichever is higher, with table preload turned off. Increase the size of the DR node during a DR event.
