Correct answer: A

Question 2 Single choice

You are creating an Oracle Cloud Infrastructure (OCI) Data Science job that will run on a recurring basis in a production environment. This job will pick up sensitive data from an Object Storage bucket, train a model, and save it to the model catalog.

How would you design the authentication mechanism for the job?

  1. A

    Package your personal OC file and keys in the job artifact.

  2. B

    Use the resource principal of the job run as the signer in the job code, ensuring there is a dynamic group for this job run with appropriate access to Object Storage and the model catalog.

  3. C

    Store your personal OCI config file and kays in the Vault, and access the Vault through the job nun resource principal

  4. D

    Create a pre-authenticated request (PAA) for the Object Storage bucket, and use that in the job code.
