The answer is to enable T3 unlimited mode on the instance. This is correct because T3 instances operate on a CPU credit model, where they accumulate credits during idle periods and spend them under load; once the credit balance is depleted, the instance is throttled to the baseline, causing performance degradation. Enabling unlimited mode allows the instance to burst beyond the baseline even after credits are exhausted, though it incurs additional charges per vCPU-hour for the surplus. On the AWS Certified SAP on SAP Specialty PAS-C01 exam, this scenario tests your understanding of burstable versus non-burstable instance families and cost optimization for variable SAP workloads—a common trap is jumping to a larger M5 instance, which provides consistent performance but at a higher baseline cost. For intermittent SAP application server spikes, T3 unlimited is the most cost-effective solution, while sustained high CPU would justify an M5. Memory tip: think “T3 Unlimited = Turbo for Temporary Traffic,” but remember it’s not free—the meter runs when credits run dry.
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 is experiencing high CPU utilization on the application server. CloudWatch metrics show that the CPU credit balance for the T3 instance is frequently depleted. What is the most cost-effective solution to resolve this issue while maintaining performance?
Why wrong: C5 instances are also non-burstable and may increase cost without addressing the credit issue.
B
Enable T3 unlimited on the instance.
T3 unlimited allows the instance to burst beyond the baseline, paying extra only when credits are exhausted, which is cost-effective for intermittent spikes.
C
Change the instance type to M5.large.
Why wrong: M5 instances are more expensive and may not be necessary if the workload is intermittent.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable T3 unlimited on the instance.
T3 instances are burstable and may run out of CPU credits under sustained load. Changing to a T3 unlimited instance avoids performance throttling but incurs additional charges if credits are exhausted. M5 instances are non-burstable and provide consistent performance. The most cost-effective solution is to switch to a T3 unlimited configuration if the workload is intermittent; however, for sustained high CPU, an M5 instance is more appropriate. The best answer here is to use T3 unlimited because it is cost-effective for variable workloads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add more vCPUs by changing to a C5 instance.
Why it's wrong here
C5 instances are also non-burstable and may increase cost without addressing the credit issue.
✓
Enable T3 unlimited on the instance.
Why this is correct
T3 unlimited allows the instance to burst beyond the baseline, paying extra only when credits are exhausted, which is cost-effective for intermittent spikes.

✗
Change the instance type to M5.large.
Why it's wrong here

✗
Increase the size of the EBS volumes.
Why it's wrong here
EBS size does not affect CPU credits.

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.
