Databricks Certified Data Engineer Professional — Question 137

A data engineer, User A, has promoted a 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.

A workspace admin, User C, inherits responsibility for managing this pipeline. User C uses the Databricks Jobs UI to take "Owner" privileges of each job. Jobs continue to be triggered using the credentials and tooling configured by User B.

An application has been configured to collect and parse run information returned by the REST API. Which statement describes the value returned in the creator_user_name field?

Answer options

• A. Once User C takes "Owner" privileges, their email address will appear in this field; prior to this, User A’s email address will appear in this field.
• B. User B’s email address will always appear in this field, as their credentials are always used to trigger the run.
• C. User A’s email address will always appear in this field, as they still own the underlying notebooks.
• D. Once User C takes "Owner" privileges, their email address will appear in this field; prior to this, User B’s email address will appear in this field.
• E. User C will only ever appear in this field if they manually trigger the job, otherwise it will indicate User B.

Correct answer: B

Explanation

The correct answer is B because User B's credentials are used to trigger the job runs, and thus their email address will always appear in the creator_user_name field. Options A, C, D, and E are incorrect as they suggest User C or User A's information appears in the field despite the job being triggered by User B's credentials.
