PAS-C01 Operations and Maintenance Practice Question
Your SAP on AWS environment uses a central S3 bucket to store SAP transport files. The operations team reports that transport import fails intermittently. Which AWS service can be used to monitor and alert on S3 API call failures?
Answer choices
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
✓
AWS CloudTrail
CloudTrail logs all S3 API calls and can be used to monitor failures via CloudWatch Logs or EventBridge. AWS Config tracks configuration changes, not API calls. CloudWatch Metrics provides S3 metrics but is not the primary service for detailed API call monitoring. Trusted Advisor offers best-practice checks, not real-time monitoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AWS CloudTrail
Why this is correct
Correct. AWS CloudTrail records S3 API calls, allowing you to monitor and alert on failures.
- ✗
AWS Config
Why it's wrong here
Incorrect. AWS Config tracks resource configuration changes and compliance, not API call-level monitoring.
- ✗
Amazon CloudWatch Metrics
Why it's wrong here
Amazon CloudWatch Metrics provides aggregated data points, such as the count of S3 4xx and 5xx errors, which is valuable for monitoring overall service health and setting alarms based on general error rate thresholds. However, it does not provide the detailed, individual API call logs required to diagnose the specific intermittent failures of transport imports. To understand the precise cause of each failure, a service capturing individual event details, rather than just metric aggregates, is necessary.
- ✗
AWS Trusted Advisor
Why it's wrong here
Incorrect. AWS Trusted Advisor provides cost, performance, and security best-practice checks, not real-time API monitoring.
