- A
Increase the unhealthy threshold count to reduce false positives.
Why wrong: Increasing the threshold delays detection of real failures.
- B
Enable HTTP/2 support on the ALB.
Why wrong: HTTP/2 does not improve health check reliability.
- C
Replace the ALB with a Network Load Balancer.
Why wrong: NLB does not perform application-level health checks.
- D
Change the health check endpoint to a static HTML page that does not require authentication.
A static endpoint avoids session overhead and is more reliable.

ALB Health Check Best Practices — SAP Web Dispatcher
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs its SAP system on AWS and uses an Application Load Balancer (ALB) to distribute traffic to SAP Web Dispatchers. The operations team reports that some users experience intermittent connectivity issues. The ALB health checks are configured to check the /sap/public/bc/icf/logon endpoint. Which configuration change would best improve the reliability of health checks?
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
✓
Change the health check endpoint to a static HTML page that does not require authentication.
The correct answer is D. Health checks should target a simple, static resource that is always available and does not require authentication. The /sap/public/bc/icf/logon endpoint requires a session and may fail due to transient authentication issues, causing false health check failures. Using a static HTML page eliminates this dependency and improves reliability. Option A is incorrect because increasing the unhealthy threshold would actually delay detection of real failures, potentially allowing unhealthy instances to receive traffic longer. Option B is incorrect because HTTP/2 is a protocol enhancement for performance, not health check reliability. Option C is incorrect because replacing the ALB with a Network Load Balancer would not address the root cause; the issue is the health check endpoint itself.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
