Which AWS Cloud design principle is being followed when a company enables AWS CloudTrail to record API activity and changes?

Enabling AWS CloudTrail to record API activity and changes directly supports the design principle of "Activate traceability." CloudTrail provides a history of API calls made against your AWS account, including who made the call, when, from where, and what resources were affected. This audit trail is crucial for security analysis, compliance auditing, and operational troubleshooting, allowing you to trace actions back to their origin. "Use serverless compute architectures" is a design principle focused on operational efficiency and scalability, not specifically on logging API activity. "Perform operations as code" emphasizes automation and consistency in managing infrastructure, which is different from auditing API calls. "Go global in minutes" refers to the ability to deploy resources across multiple AWS regions quickly, a principle of global reach and agility, not traceability.
