Show answer and explanation
Correct answers: B, C, E
Explanation
To create a Unity Catalog-enabled all-purpose cluster, the cluster must be attached to a Unity Catalog-enabled workspace, use a runtime version compatible with Unity Catalog, and have an instance profile with sufficient IAM permissions. There is no Unity Catalog-specific toggle in the cluster settings, and both Standard and High Concurrency modes can be used.
- A. Incorrect.
Unity Catalog does not have a specific toggle in the cluster configuration. Instead, it is configured at the workspace and runtime level.
- B. Correct.
Unity Catalog requires the cluster to be attached to a workspace that has Unity Catalog enabled. Without this, the cluster cannot use Unity Catalog features.
- C. Correct.
The cluster must use a runtime version that explicitly supports Unity Catalog. Older runtime versions may not include this support.
- D. Incorrect.
High Concurrency clusters are supported with Unity Catalog, so this is not a requirement. Both Standard and High Concurrency modes can be used.
- E. Correct.
An instance profile with appropriate IAM permissions is required to access Unity Catalog features, such as managing access to data in Unity Catalog.
