SOA-C02 Monitoring, Logging, and Remediation Practice Question
A company needs to retain API call logs for 7 years for compliance. Which AWS service should be used to store these logs?
⚠ Common exam trap
Test-takers frequently confuse CloudTrail (API auditing) with CloudWatch Logs (operational logs) or Config (configuration history), but only CloudTrail captures the specific API call logs required for compliance retention.

Correct answer & explanation
✓
AWS CloudTrail
AWS CloudTrail is the correct service because it records API activity across your AWS infrastructure and can be configured to store logs in an S3 bucket with lifecycle policies that retain data for 7 years. CloudTrail is specifically designed for auditing and compliance, capturing management and data plane API calls, and supports long-term retention via S3 object locking or lifecycle rules.
