The answer is to add an additional SAP application server in the same Availability Zone, as this is the most cost-effective solution for handling peak load when vertical scaling is exhausted. This approach leverages horizontal scaling by distributing the CPU-intensive workload across multiple application server instances, which allows the SAP system to absorb traffic spikes without requiring a larger instance type. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of the trade-off between vertical and horizontal scaling in the context of SAP architecture, specifically that once you hit the ceiling of the largest instance type, adding more servers is the only viable path for cost-effective SAP peak load horizontal scaling. A common trap is to confuse reserved instances with performance fixes—reserved instances only reduce cost, not CPU usage. Memory tip: “Maxed out vertically? Go wide, not tall.”
PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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 running on AWS is experiencing high CPU usage on the application server during peak hours. The system is already using the largest instance type available in the current generation. What is the most cost-effective solution to handle the peak load?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add an additional SAP application server in the same Availability Zone
Option B is correct because adding an additional application server distributes the load horizontally. Option A is incorrect because vertical scaling is not possible if max instance already used. Option C is incorrect because buying reserved instances does not solve peak CPU issue. Option D is incorrect because enabling Auto Scaling for app tier but without additional instances it doesn't help.
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.
✗
Upgrade to a larger instance type from a different instance family
Why it's wrong here
Largest instance already in use; upgrading may not be possible.
✗
Purchase Reserved Instances to reduce cost and allocate more resources
Why it's wrong here
Reserved Instances do not increase capacity.
✓
Add an additional SAP application server in the same Availability Zone
Why this is correct
Horizontal scaling distributes load across multiple servers.

✗
Use Auto Scaling to automatically add instances during peak hours
Why it's wrong here
Auto Scaling requires pre-configured instances; but adding instances is correct, but the option is incomplete.

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.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
