Which feature of AWS CloudTrail enables you to monitor API calls made in your account?

The feature of AWS CloudTrail that enables you to monitor API calls made in your account is event history. Event history provides a comprehensive record of AWS API calls made across your account. This includes details such as who made the call, when it was made, the source IP address, and the actions that were performed. This capability is crucial for auditing and compliance purposes as it allows administrators to track changes and understand the behavior of users within the AWS environment.

Other options do not directly address the monitoring of API calls. Logging services refer to a broader category that encompasses various logging mechanisms not specifically tied to the event monitoring capabilities of CloudTrail. Resource tracking could imply monitoring the status of resources but does not specifically focus on the API calls that CloudTrail captures. Activity monitoring is a more general term that does not specifically relate to the detailed logs and audit trails provided by event history. Thus, event history is the most accurate choice for monitoring API calls in AWS CloudTrail.
