Quick Answer
The correct metrics to examine are VolumeReadBytes, VolumeWriteBytes, and VolumeQueueLength. VolumeReadBytes and VolumeWriteBytes directly measure the throughput of your EBS volumes, which is critical for confirming whether the storage subsystem is meeting the I/O demands of an SAP workload. VolumeQueueLength indicates the number of pending I/O requests waiting to be processed; a persistently high queue length suggests the volume is saturated and cannot keep up with the application’s requests. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to distinguish between EBS-specific performance metrics and unrelated instance-level metrics like BurstBalance or CPUCreditBalance, which are common traps. Remember that BurstBalance applies to EBS volumes using gp2/gp3 burst credits, not to t2/t3 instance credits, and CPUCreditBalance is for CPU, not storage. A helpful memory tip: for EBS performance, think “Read, Write, and Wait” — VolumeReadBytes, VolumeWriteBytes, and VolumeQueueLength.
This PAS-C01 practice question tests your understanding of operations and maintenance. 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 where the SAP application is slow. The administrator suspects that the EBS volumes are not meeting performance requirements. Which THREE metrics should be examined in Amazon CloudWatch to confirm this? (Choose THREE.)
VolumeQueueLength
Indicates pending I/O requests.
VolumeReadBytes
Measures read throughput.
VolumeWriteBytes
Measures write throughput.
CPUCreditBalance
Why wrong: CPUCreditBalance is for CPU credits, not EBS.
BurstBalance
Why wrong: BurstBalance is for T2/T3 instances, not EBS volumes.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
VolumeQueueLength
Options B, C, and D are correct. VolumeReadBytes and VolumeWriteBytes measure throughput, and VolumeQueueLength indicates pending I/O requests. Option A is not correct because BurstBalance is for t2/t3 instances, not EBS. Option E is not correct because CPUCreditBalance is for CPU credits.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
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.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
