What type of record does CloudTrail event history provide?

CloudTrail event history provides historical records of the last 90 days of events, which is essential for monitoring user activity and API usage within an AWS account. This feature allows administrators to review actions taken on the AWS environment, enhancing security and compliance by providing insights into resource usage, changes made to configurations, and user access patterns.

The ability to access event history for the past 90 days allows teams to investigate and analyze historical data without the need for persistent logging setup beyond this time frame. This can be critical in identifying unauthorized access attempts or changes made to critical resources that need to be tracked for security purposes.

Other options either pertain to different functionalities such as performance metrics or logs which are not specific to the event history offered by CloudTrail. Audit reports and real-time logging, while important, do not specifically denote the nature of the historical recordings that CloudTrail provides, which are indeed focused on the last 90 days of API activity.
