Answer: AWS CloudTrail

AWS CloudTrail is the correct answer because it is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. CloudTrail logs, continuously monitors, and retains account activity related to actions across your AWS infrastructure, including API calls made to Amazon Bedrock. **Key points about AWS CloudTrail:** - Records API calls and related events made in your AWS account - Delivers log files to an Amazon S3 bucket - Helps with security analysis, resource change tracking, and troubleshooting - Enables compliance auditing by providing a history of AWS API calls **Why other options are incorrect:** - **AWS Lambda**: A serverless compute service for running code without provisioning servers - **Amazon GuardDuty**: A threat detection service that continuously monitors for malicious activity - **AWS CodeDeploy**: A deployment service that automates application deployments to various compute services
