PAS-C01 Operations and Maintenance Practice Question
An SAP administrator needs to ensure that an EC2 instance hosting SAP HANA is rebooted automatically after a hardware failure. Which AWS feature provides this capability?
⚠ Common exam trap
Candidates often confuse Auto Scaling groups (which replace instances) with EC2 Auto Recovery (which recovers the same instance), leading them to choose Auto Scaling for automatic reboot, but Auto Scaling does not reboot the same instance and can cause data loss for stateful applications like SAP HANA.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EC2 Auto Recovery
EC2 Auto Recovery is the correct AWS feature because it automatically recovers an EC2 instance when a hardware failure on the underlying physical host is detected. For SAP HANA workloads, this ensures the instance is rebooted on a healthy host without manual intervention, maintaining high availability for critical database operations.
