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 is experiencing performance degradation. The CloudWatch metrics show that the EBS volumes used for the HANA data files have an average queue length of 10 and average latency of 50 ms. 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 EBS volume's provisioned IOPS are insufficient for the workload.
An average EBS queue length of 10 and average latency of 50 ms indicate that the volume is saturated with I/O requests. The queue length persistently exceeds the recommended threshold (typically <1 for optimal performance), and latency spikes above the 1–10 ms range for gp3 or io2 volumes. This directly points to insufficient provisioned IOPS for the SAP HANA workload, causing requests to queue up and wait for service.
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.
✗
EBS encryption is causing additional overhead.
Why it's wrong here
Encryption overhead is negligible.
✗
EBS snapshots are being taken too frequently.
Why it's wrong here
Snapshots may cause brief latency but not sustained queue depth.
✓
The EBS volume's provisioned IOPS are insufficient for the workload.
Why this is correct
Insufficient IOPS cause queuing and increased latency.
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.
✗
EBS optimization is not enabled on the instance.
Why it's wrong here
EBS optimization is enabled by default on current generation instances.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse high queue length with a snapshot or encryption issue, but AWS explicitly documents that queue length and latency are the primary indicators of IOPS exhaustion, not of background operations like snapshots or encryption.
Detailed technical explanation
How to think about this question
EBS queue length represents the number of pending I/O requests waiting for the storage subsystem. For SAP HANA, which issues many small random writes, a sustained queue depth above 1 with latency >20 ms indicates that the volume's IOPS ceiling has been hit. Provisioned IOPS (io1/io2) or baseline IOPS (gp3) must match the workload's peak demand; otherwise, the EBS driver throttles requests, causing queuing and latency. In practice, SAP HANA on AWS recommends io2 Block Express volumes with sufficient IOPS to keep queue depth near zero.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
