What describes the contents of workspace audit logs regarding job events created through the REST API?

The choice indicating that User A's identity will be associated with job creation and User B's for job runs is correct because in typical scenarios involving job events created through the REST API in Databricks, the context of the user performing specific actions is crucial.

When a job is created through the REST API, it is registered under the identity of the user (or service principal) who initiated the creation. This means that User A, who executes the API call to create the job, will have their identity logged as the creator of that job. Conversely, when the job is subsequently run, the identity of the user or service principal that triggers the job execution will be recorded. In this case, if User B is the one who executes or initiates the job run, their identity will be associated with that event.

This distinction illustrates how the audit logs differentiate between the user roles in different stages of job management, providing a clear trace of actions performed and who performed them at each step. This capability is essential for tracking job deployments and executions for auditing and security purposes within Databricks.
