PAS-C01 Operations and Maintenance Practice Question
An operations team needs to monitor the disk space usage of SAP application servers running on EC2. Which combination of AWS services should they use?
⚠ Common exam trap
It's easy for candidates to assume standard EC2 CloudWatch metrics include disk space usage, but they only include disk read/write operations (I/O), not percentage of disk space used, so the CloudWatch agent is mandatory for this specific monitoring requirement.

Correct answer & explanation
✓
Amazon CloudWatch agent and Amazon CloudWatch alarms
Amazon CloudWatch agent is required to collect custom metrics like disk space usage from EC2 instances, as the standard CloudWatch metrics only cover CPU, memory, network, and disk I/O. By installing the agent and configuring it to report disk space metrics, you can then set CloudWatch alarms to trigger notifications when thresholds are breached, enabling proactive monitoring of SAP application servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon CloudWatch and AWS CloudTrail
Why it's wrong here
CloudWatch without agent does not provide disk metrics; CloudTrail is for API auditing.
- ✓
Amazon CloudWatch agent and Amazon CloudWatch alarms
Why this is correct
CloudWatch agent collects disk metrics, and alarms can notify when thresholds are exceeded.
- ✗
AWS Lambda and Amazon DynamoDB
Why it's wrong here
Lambda alone cannot collect metrics; DynamoDB is not needed.
- ✗
Amazon S3 and Amazon SNS
Why it's wrong here
S3 is for storage; SNS is for notifications but lacks metric collection.
