  • A

    Since it’s just a single job and we need to run every hour, we can use an all-purpose cluster

  • B

    The job cluster is best suited for this purpose.

  • C

    Use Azure VM to read and write delta tables in Python

  • D

Reveal correct answer

Correct answer: B

Explanation

The answer is, The Job cluster is best suited for this purpose.


Since you don't need to interact with the notebook during the execution especially when it's a scheduled job, job cluster makes sense. Using an all-purpose cluster can be twice as expensive as a job cluster.

FYI,

When you run a job scheduler with option of creating a new cluster when the job is complete it terminates the cluster. You cannot restart a job cluster.
