PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP HANA on AWS and needs to ensure high availability for the database. Which AWS service should be used to automatically recover the HANA primary instance in case of an instance failure?
⚠ Common exam trap
It's easy for candidates to assume AWS services like CloudWatch or Lambda are sufficient for automatic recovery, but the question specifically asks for the service that automatically recovers the HANA primary instance via failover, which requires DNS-level rerouting provided by Route 53 health checks and failover routing.

Correct answer & explanation
✓
Amazon Route 53 health checks and failover routing
Amazon Route 53 health checks and failover routing can automatically detect an instance failure and route traffic to a standby HANA primary instance. By configuring a Route 53 DNS failover record with health checks against the primary instance, DNS resolution is updated to point to the secondary instance when the primary becomes unhealthy, enabling automated recovery without manual intervention.
