The answer is that the instance is a burstable performance instance like a T3, not an r5. This is correct because r5 instances are non-burstable, dedicated-performance instances that do not use CPU credits; they provide consistent, full CPU performance at all times. A rapidly depleting CPU credit balance is a technical indicator that the instance is actually a burstable type, which relies on CPU credits for baseline performance and accumulates or spends them based on workload. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of EC2 instance families and the critical distinction between burstable (T-series) and standard (M, R, C-series) instances, especially in the context of SAP HANA workloads that require sustained high CPU. A common trap is assuming all instances use CPU credits, but only T-series do. Memory tip: if you see CPU credits, think “T” for “temporary boost”—never for an R or M instance.
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 administrator is troubleshooting a performance issue on an SAP HANA instance running on an EC2 instance. The instance type is r5.8xlarge with 256 GB of RAM. The administrator notices that the instance's CPU credit balance is depleting rapidly. 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 instance is a burstable performance instance (e.g., T3) not an r5
Option A is correct because r5 instances are not burstable performance instances; they have dedicated vCPUs and do not use CPU credits. The depletion indicates the instance is not an r5 but possibly a T3 instance. Option B and D are not related to CPU credits. Option C is a misunderstanding.
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 instance is using EBS-optimized with insufficient bandwidth
Why it's wrong here
EBS optimization does not affect CPU credits.
✗
The SAP application is using too much memory
Why it's wrong here
Memory usage doesn't deplete CPU credits.
✗
The instance has a high network throughput causing CPU overhead
Why it's wrong here
Network throughput does not directly deplete CPU credits.
✓
The instance is a burstable performance instance (e.g., T3) not an r5
Why this is correct
Burstable instances earn CPU credits; r5 instances do not have CPU credits.

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 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.
