Select 3You are tasked with creating a Unity Catalog (UC)-enabled all-purpose cluster in Databricks. Which of the following steps or considerations are necessary to successfully configure the cluster?
- A
Ensure that the cluster is attached to a workspace with Unity Catalog configured.
- B
Set the cluster access mode to 'No Isolation Shared'.
- C
Attach a UC-enabled cluster to the relevant UC-enabled metastore.
- D
Enable the Photon runtime for the cluster.
- E
Set the cluster's access mode to 'Single User' or 'Shared'.
Show answer and explanation
Correct answers: A, C, E
Explanation
To create a Unity Catalog-enabled all-purpose cluster, you must ensure that the workspace is configured with Unity Catalog and a UC-enabled metastore. Additionally, the cluster must use an appropriate access mode ('Single User' or 'Shared') to integrate with Unity Catalog. While enabling Photon enhances performance, it is not a mandatory step for creating a UC-enabled cluster.
- A. Correct.
Correct. Unity Catalog requires the workspace to have Unity Catalog properly configured, including a UC-enabled metastore.
- B. Incorrect.
Incorrect. The correct access modes for UC-enabled clusters are 'Single User' or 'Shared', not 'No Isolation Shared'.
- C. Correct.
Correct. A UC-enabled cluster must be attached to a Unity Catalog-enabled metastore to properly access the catalog's features.
- D. Incorrect.
Incorrect. While Photon can enhance performance, it is not a requirement for creating a UC-enabled cluster.
- E. Correct.
Correct. Unity Catalog-compatible clusters must use either 'Single User' or 'Shared' access mode to enforce security and achieve proper integration with the catalog.
