PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP system on AWS uses an Application Load Balancer (ALB) to distribute traffic to multiple SAP application servers. The ALB is configured with a TCP listener. Users report that some sessions are terminated unexpectedly. What is the MOST likely cause?
⚠ Common exam trap
Candidates often confuse the ALB's idle timeout with the target group health check interval, assuming that frequent health checks cause session drops, when in fact health checks do not affect established connections.
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 ALB idle timeout setting is shorter than the SAP session timeout.
The ALB's idle timeout setting controls how long the load balancer keeps a connection open without data transfer. If this timeout is shorter than the SAP session timeout, the ALB will close the connection prematurely, causing the user's session to be terminated unexpectedly. This is a common mismatch when long-running SAP transactions or background jobs do not send data within the ALB's idle timeout window.
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 ALB is not configured with SSL termination.
Why it's wrong here
SSL termination is not required for SAP protocol on TCP.
- ✗
The target group health check interval is set too low.
Why it's wrong here
Low health check interval can cause flapping but not session termination.
- ✓
The ALB idle timeout setting is shorter than the SAP session timeout.
Why this is correct
If idle timeout is lower than SAP session timeout, connections are dropped.
- ✗
The ALB is configured with cross-zone load balancing disabled.
Why it's wrong here
Cross-zone load balancing affects load distribution, not session persistence.
