SOA-C02 Monitoring, Logging, and Remediation Practice Question
A SysOps administrator needs to monitor the disk space usage on an EC2 instance running Windows Server. Which actions are required to collect this metric? (Select TWO.)
⚠ Common exam trap
Many exam-takers confuse the CloudWatch Logs agent with the CloudWatch agent, or assume that EC2 status checks or Performance Monitor can directly send disk metrics to CloudWatch without additional configuration.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an IAM role with permissions to publish custom metrics and attach it to the instance.
The CloudWatch agent requires permissions to publish custom metrics to CloudWatch. An IAM role with the appropriate policy (e.g., CloudWatchAgentServerPolicy) must be attached to the EC2 instance to allow the agent to send disk space metrics. Option E is correct because the CloudWatch agent must be installed and configured with a JSON configuration file that includes the "disk" section to collect disk space utilization metrics, which are not available by default from EC2.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Install the CloudWatch Logs agent to monitor disk usage logs.
Why it's wrong here
The CloudWatch Logs agent collects logs, not metrics.
- ✗
Enable EC2 status checks to monitor disk health.
Why it's wrong here
Status checks check instance health, not disk space.
- ✗
Use Windows Performance Monitor to track disk space and send to CloudWatch.
Why it's wrong here
Performance Monitor does not natively send to CloudWatch.
- ✓
Create an IAM role with permissions to publish custom metrics and attach it to the instance.
Why this is correct
The instance needs IAM permissions to publish metrics.
- ✓
Install the CloudWatch agent on the instance and configure it to collect disk metrics.
Why this is correct
The CloudWatch agent can collect disk space metrics.
