This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 needs to monitor the disk I/O performance of EBS volumes attached to an SAP HANA instance. Which AWS service should be used to capture the average read latency and queue depth metrics?
AWS Config
Why wrong: AWS Config tracks configuration changes, not performance metrics.
AWS Health
Why wrong: AWS Health provides service health status, not performance metrics.
Amazon CloudWatch
CloudWatch collects and provides metrics like AverageReadLatency and QueueDepth for EBS volumes.
AWS CloudTrail
Why wrong: CloudTrail records API calls, not performance metrics.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudWatch
Amazon CloudWatch provides the metrics necessary to monitor disk I/O performance, including `VolumeReadOps`, `VolumeQueueLength`, and `VolumeReadBytes` for EBS volumes. These metrics allow you to calculate average read latency (by dividing `VolumeReadBytes` by `VolumeReadOps`) and directly observe queue depth via `VolumeQueueLength`, making it the correct service for SAP HANA disk I/O monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Config
Why it's wrong here
AWS Config tracks configuration changes, not performance metrics.
AWS Health
Why it's wrong here
AWS Health provides service health status, not performance metrics.
Amazon CloudWatch
Why this is correct
CloudWatch collects and provides metrics like AverageReadLatency and QueueDepth for EBS volumes.

AWS CloudTrail
Why it's wrong here
CloudTrail records API calls, not performance metrics.
Common exam traps
The trap here is that candidates may confuse AWS CloudTrail (which logs API calls) with CloudWatch (which monitors performance metrics), or assume AWS Config or AWS Health provide operational performance data when they are designed for configuration auditing and service health notifications, respectively.
Detailed technical explanation
EBS metrics in CloudWatch are published at 1-minute intervals for standard volumes and at 1-second intervals for Provisioned IOPS volumes (when detailed monitoring is enabled). Average read latency is derived by dividing `VolumeReadBytes` by `VolumeReadOps` over the same period, while `VolumeQueueLength` directly indicates the number of pending I/O requests; a sustained queue depth above 1 often signals that the volume is saturated and may require scaling IOPS or throughput. In SAP HANA, high queue depth can directly impact database transaction response times, making these metrics critical for performance tuning.
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.
