PAS-C01 Technology Practice Question
An SAP system on AWS is experiencing slow performance. The SAP team suspects that the Amazon EBS volumes used for the database are not providing sufficient IOPS. Which step should be taken to identify the bottleneck?
⚠ Common exam trap
Test-takers frequently confuse high-level advisory tools (Trusted Advisor) or network-focused logs (VPC Flow Logs) with the precise storage performance metrics needed to diagnose an IOPS bottleneck, overlooking CloudWatch as the definitive source for EBS performance data.

Correct answer & explanation
✓
Monitor the EBS volume metrics in CloudWatch
Amazon CloudWatch provides detailed metrics for EBS volumes, including `VolumeReadOps`, `VolumeWriteOps`, `VolumeQueueLength`, and `VolumeThroughputPercentage`. By monitoring these metrics, you can directly determine whether the EBS volume is reaching its provisioned IOPS limit or experiencing queue buildup, which would confirm an IOPS bottleneck. This is the most direct and actionable step to diagnose insufficient IOPS for the SAP database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Monitor the EBS volume metrics in CloudWatch
Why this is correct
CloudWatch metrics like VolumeQueueLength indicate IOPS saturation.
- ✗
Use AWS Trusted Advisor to check performance
Why it's wrong here
Trusted Advisor gives recommendations, not real-time metrics.
- ✗
Enable VPC Flow Logs to analyze network traffic
Why it's wrong here
Flow Logs analyze network, not disk I/O.
- ✗
Review the AWS Config rules for EBS
Why it's wrong here
Config tracks configuration, not performance.
