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. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 experiences intermittent performance issues. CloudWatch metrics show high CPU credit usage on the t3.large EC2 instance hosting the SAP application. The instance is configured as a 'standard' placement group. What is the MOST likely cause and recommended action?
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 burstable instance is exhausting its CPU credits. Change to a non-burstable instance.
The t3.large is a burstable instance that earns CPU credits when idle and spends them when active. SAP applications often have sustained CPU demands that can exhaust the credit balance, causing performance throttling. Switching to a non-burstable instance (e.g., m5.large) provides consistent baseline CPU performance without credit-based limitations.
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 size is too small. Move to a larger t3 instance.
Why it's wrong here
Larger t3 instances still have credit limits and can also be exhausted.
✓
The burstable instance is exhausting its CPU credits. Change to a non-burstable instance.
Why this is correct
T3 instances use CPU credits; sustained high usage depletes them, causing throttling.
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 placement group is causing network bottlenecks. Move to a cluster placement group.
Why it's wrong here
Placement group type does not affect CPU credits.
✗
The EBS volume is not provisioned with enough IOPS. Increase the volume size.
Why it's wrong here
EBS performance does not affect CPU credits.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume a larger burstable instance (Option A) solves the problem, but the PAS-C01 exam tests understanding that burstable instances are fundamentally inappropriate for sustained SAP workloads, regardless of size.
Detailed technical explanation
How to think about this question
T3 instances use a CPU credit model where each vCPU minute of usage consumes credits; once the accrued credit balance is depleted, the instance is throttled to the baseline (e.g., 30% for t3.large). SAP applications like SAP NetWeaver or SAP HANA often require consistent CPU performance, making burstable instances unsuitable for production workloads. AWS recommends using non-burstable instance families (e.g., M5, R5) for SAP to avoid credit exhaustion and ensure predictable performance.
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.
TExam Day Tips
→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.
