PAS-C01 Design of SAP Workloads on AWS Practice Question
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 is experiencing performance issues during peak hours. The SAP application servers are running on EC2 instances behind a Network Load Balancer (NLB). The NLB is configured to use cross-zone load balancing. The issue is that one application server receives significantly more traffic than others. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The flow hash algorithm is causing an uneven distribution of client traffic
Option D is correct because NLB distributes traffic based on flow hash, which can lead to uneven distribution, especially with fewer flows. Option A is wrong because NLB does not use round-robin. Option B is wrong because NLB does not have a health check that would skew traffic. Option C is wrong because NLB distributes traffic regardless of instance size.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 application servers have different instance sizes, causing the NLB to send more traffic to larger instances
Why it's wrong here
NLB does not consider instance size for traffic distribution.
✗
The NLB is using round-robin algorithm and one server is slower
Why it's wrong here
NLB uses a flow hash algorithm, not round-robin.
✓
The flow hash algorithm is causing an uneven distribution of client traffic
Why this is correct
NLB uses a flow hash based on source IP, port, and protocol; with few clients, distribution can be uneven.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The health check is failing on the other servers
Why it's wrong here
If health check fails, those servers would be removed from rotation; they are receiving less traffic, not more.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
