QUESTION: 48

A data engineer, User A, has promoted a new pipeline to production by using the REST API to programmatically create several jobs. A DevOps engineer, User B, has configured an external orchestration tool to trigger job runs through the REST API. Both users authorized the REST API calls using their personal access tokens.

Which statement describes the contents of the workspace audit logs concerning these events?

Because the REST API was used for job creation and triggering runs, a Service Principal will be automatically used to identify these events.
Because User B last configured the jobs, their identity will be associated with both the job creation events and the job run events.
Because these events are managed separately, User A will have their identity associated with the job creation events and User B will have their identity associated with the job run events.
Because the REST API was used for job creation and triggering runs, user identity will not be captured in the audit logs.
Because User A created the jobs, their identity will be associated with both the job creation events and the job run events.

The exam is administered in a controlled environment, often through a proctoring service like Pearson VUE, which ensures the integrity of the testing process. It is important to familiarize yourself with the testing interface and the types of questions you will face, as this will help reduce anxiety and allow you to focus entirely on the technical challenges presented.

The duration of the exam and the passing score are determined by the vendor, and you should check the official Databricks certification website for the most current information regarding these details. Because the exam is designed to test professional-level competency, you should expect questions that are nuanced and require careful reading. Do not rush through the questions, as small details in the scenario description can often change the correct answer. If you find yourself stuck on a particularly difficult question, it is often better to flag it for review and move on to the next one, returning to it once you have completed the rest of the exam. This strategy helps you manage your time effectively and ensures that you do not leave any questions unanswered.
