PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP system on AWS uses a Classic Load Balancer to distribute traffic to web dispatchers. The system is experiencing intermittent timeouts. What is the most likely cause?
⚠ Common exam trap
Many exam-takers confuse health check intervals with idle timeout, assuming a short health check interval causes timeouts, when in reality idle timeout is the direct cause of dropped connections during periods of inactivity.

Correct answer & explanation
✓
The load balancer idle timeout setting is too low.
The Classic Load Balancer has a default idle timeout of 60 seconds for TCP connections. If the SAP application or web dispatchers keep connections open longer than this without data transfer (e.g., during long-running reports or user think time), the load balancer will close the connection, causing intermittent timeouts. Increasing the idle timeout to match the application's keep-alive settings resolves this.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The security group for the load balancer is blocking traffic.
Why it's wrong here
Security groups would block connections entirely, not cause intermittent timeouts.
- ✗
Sticky sessions are enabled on the load balancer.
Why it's wrong here
Stickiness does not cause timeouts.
- ✗
The load balancer health check interval is too short.
Why it's wrong here
Health check interval affects health detection, not timeouts.
- ✓
The load balancer idle timeout setting is too low.
Why this is correct
Low idle timeout can cause premature connection termination.
