The correct answer involves increasing the healthy threshold count and changing the health check path to a simpler endpoint. Raising the healthy threshold prevents flapping by requiring more consecutive successful checks before marking an instance healthy, which smooths out transient application delays common in SAP workloads. Changing the health check path to a lightweight endpoint, such as a static HTML page or a dedicated health check servlet, reduces false unhealthy instances by avoiding complex SAP application logic that may time out or return non-200 responses under load. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this tests your understanding of ALB health check configuration for SAP, specifically how to tune thresholds and endpoints to match SAP’s slower startup and session behavior. A common trap is confusing the healthy threshold with the unhealthy threshold, or assuming a deeper application path is better. Memory tip: “Thicker threshold, thinner path” — increase the count, simplify the target.
PAS-C01 Operations and Maintenance Practice Question
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.
An SAP system on AWS uses an Application Load Balancer (ALB) to distribute traffic across multiple EC2 instances. The operations team notices that some instances are marked as unhealthy even though the application is running correctly. Which TWO actions could resolve this issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the healthy threshold count.
Option A is correct because increasing the healthy threshold can prevent flapping. Option D is correct because changing the health check path to a simpler endpoint can reduce false failures. Option B is wrong because decreasing the interval might increase load. Option C is wrong because associating an Elastic IP is not relevant. Option E is wrong because changing the protocol to TCP is not possible with ALB.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Increase the healthy threshold count.
Why this is correct
A higher threshold reduces the chance of flapping.
Related concept
Static NAT maps one inside address to one outside address.
✗
Associate an Elastic IP address with each instance.
Change the health check path to a simpler endpoint.
Why this is correct
A simpler endpoint is more likely to respond correctly.
Related concept
Static NAT maps one inside address to one outside address.
✗
Decrease the health check interval.
Why it's wrong here
A shorter interval might cause more false negatives.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.

Variation 1. An SAP system is deployed across multiple Availability Zones using an Application Load Balancer (ALB). The Operations team notices that during a failover test, the ALB is sending traffic to unhealthy instances. Which configuration change would ensure the ALB stops sending traffic to unhealthy targets?
medium
A.Enable sticky sessions (session affinity).
✓ B.Configure a health check with appropriate thresholds and interval.
C.Increase the deregistration delay value.
D.Enable cross-zone load balancing.
Why B: Option C is correct because configuring health checks properly ensures the ALB marks instances as unhealthy and stops routing traffic. Option A is wrong because increasing deregistration delay only affects how long connections are drained, not health check behavior. Option B is wrong because cross-zone load balancing distributes traffic across AZs, not health. Option D is wrong because enabling sticky sessions does not affect health routing.
