Using AWS Config to record, audit, and evaluate changes to AWS resources to enable traceability is an example of which AWS Well-Architected Framework pillar?

Explanations:

AWS Config helps with security by tracking changes to resources, which supports auditing, traceability, and compliance, all core to the Security pillar.

Performance efficiency involves using resources efficiently to meet system requirements, which isn’t directly addressed by AWS Config’s tracking and auditing.

Cost optimization seeks to reduce unnecessary expenses, which is not the primary function of AWS Config, as it focuses on security and compliance instead.
