PAS-C01 Operations and Maintenance Practice Question
An SAP administrator needs to review API calls made by a user who accidentally deleted an S3 bucket used for SAP backups. Which AWS service provides a record of these API calls?
⚠ Common exam trap
Watch out — candidates often confuse Amazon S3 server access logs (which log object-level requests) with AWS CloudTrail (which logs management-plane API calls), leading them to select Option A when the question specifically asks about API calls that deleted the bucket itself.

Correct answer & explanation
✓
AWS CloudTrail
AWS CloudTrail is the correct service because it records all API calls made to the AWS environment, including S3 bucket deletion events. When a user accidentally deletes an S3 bucket, CloudTrail captures the event details such as the user identity, source IP, and timestamp, enabling the SAP administrator to audit the action. This is essential for security analysis and operational troubleshooting in the context of SAP backups.
