SOA-C02 Monitoring, Logging, and Remediation Practice Question
Network Topology
Refer to the exhibit. The command returns no datapoints for CPUUtilization for the specified instance. What is the most likely reason?
⚠ Common exam trap
Many exam-takers assume missing datapoints are due to a configuration issue (like detailed monitoring not enabled or wrong period), when in fact the instance simply wasn't running during the queried time window.

Correct answer & explanation
✓
The instance was stopped or did not emit metrics during the specified time range.
The most likely reason for no datapoints is that the instance was stopped or did not emit metrics during the specified time range. CloudWatch only retains and returns metric data when the instance is running and the CloudWatch agent or EC2 hypervisor is actively publishing CPUUtilization. If the instance was in a stopped state, no metrics are generated, resulting in an empty response from the GetMetricStatistics API call.
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 was stopped or did not emit metrics during the specified time range.
Why this is correct
If the instance is stopped, no metrics are emitted.
- ✗
The metric name is incorrect.
Why it's wrong here
CPUUtilization is a valid metric for EC2.
- ✗
The instance does not have detailed monitoring enabled.
Why it's wrong here
Basic monitoring (5-minute) is enabled by default; the period matches.
- ✗
The period of 300 seconds is too short.
Why it's wrong here
300 seconds (5 minutes) is a valid period.
