Correct answers: A, B, D

Explanation

To automate the workflow using the Databricks REST API, you first need to clone the existing job using the POST /api/2.1/jobs/create endpoint with the appropriate configuration. Once the job is cloned, you can trigger a run using the POST /api/2.1/jobs/run-now endpoint. Finally, to retrieve the output of the triggered run, use the GET /api/2.1/jobs/runs/get-output endpoint. Other endpoints like GET /api/2.1/jobs/export or DELETE /api/2.1/jobs/delete are not relevant in this specific scenario.

  • A. Correct.

    Correct. The POST /api/2.1/jobs/create endpoint is used to create a new job, and you can provide the configuration of the existing job to clone it.

  • B. Correct.

    Correct. The POST /api/2.1/jobs/run-now endpoint is used to trigger a run for the newly created (cloned) job.

  • C. Incorrect.

    Incorrect. The GET /api/2.1/jobs/export endpoint is used to export job configurations, but it is not necessary in this workflow since you can directly create a new job using the configuration.

  • D. Correct.

    Correct. The GET /api/2.1/jobs/runs/get-output endpoint is used to programmatically retrieve the output of a specific job run.

  • E. Incorrect.

    Incorrect. While the DELETE /api/2.1/jobs/delete endpoint is used to delete jobs, it is not specified in this scenario that the cloned job needs to be removed.
