Correct answer & explanation
✓
SAP HANA System Replication (HSR) with Pacemaker
SAP HANA System Replication (HSR) with Pacemaker provides synchronous replication and automatic failover, making it the appropriate solution for high availability across Availability Zones. Amazon EBS Multi-Attach is incorrect because it is limited to a single AZ and not designed for SAP HANA replication. AWS DMS is for database migration, not ongoing HA. Amazon RDS Multi-AZ is for RDS databases and does not support SAP HANA.
