PAS-C01 Technology Practice Question
An SAP system on AWS is configured with an Application Load Balancer (ALB) for health checks. The ALB marks all targets as unhealthy. The health check path is /sap/public/health.html, and the SAP Web Dispatcher is configured to serve this file. What is the most likely cause of the health check failure?
Answer choices
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
✓
The security group for the Web Dispatcher does not allow traffic from the ALB.
ALB health checks originate from private IP addresses within the VPC. If the SAP Web Dispatcher's security group does not allow inbound traffic from the ALB's security group, the health check requests will be blocked. Path or port issues would also cause failures, but the most common cause is security group misconfiguration.
