PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is deploying SAP on AWS and wants to ensure that the SAP system can automatically recover from an EC2 instance failure. Which AWS feature should be used?
⚠ Common exam trap
Watch out — candidates often confuse Elastic Load Balancer health checks with instance recovery, but ELB only manages traffic distribution and does not perform any recovery action on the instance itself.

Correct answer & explanation
✓
EC2 Auto Recovery with CloudWatch alarms
EC2 Auto Recovery, configured via a CloudWatch alarm based on the StatusCheckFailed metric, automatically recovers an EC2 instance by restarting it on a new host if the underlying hardware fails or becomes impaired. This is the correct AWS feature for automatic recovery from an EC2 instance failure, as it directly addresses instance-level hardware issues without requiring manual intervention or reconfiguration.
