NEW QUESTION # 82
Which of the following statements are true about a lakehouse?

A. Lakehouse do not support SQL

NEW QUESTION # 83
What is true for Delta Lake?

A. Primary and foreign key constraints can be leveraged to ensure duplicate values are never entered into a dimension table.
B. Views in the Lakehouse maintain a valid cache of the most recent versions of source tables at all times.
C. Z-ORDER can only be applied to numeric values stored in Delta Lake tables.
D. Delta Lake automatically collects statistics on the first 32 columns of each table, which are leveraged in data skipping based on query filters.

Answer: D

Explanation:
* Delta Lake automatically collects statistics on the first 32 columns of each table. These statistics help optimize query performance through data skipping, which allows Databricks to scan only relevant parts of a table.
* This feature significantly improves query efficiency, especially when dealing with large datasets.
Why Other Options Are Incorrect:
* Option A: Views do not cache the most recent versions of the source table; they are recomputed when queried.
* Option C: Z-ORDER can be applied to any data type, including strings, to optimize read performance.
* Option D: Delta Lake does not enforce primary or foreign key constraints.
Reference: Delta Lake Optimization

NEW QUESTION # 84
A Delta Lake table was created with the below query:

Consider the following query:
DROP TABLE prod.sales_by_store -
If this statement is executed by a workspace admin, which result will occur?

A. Nothing will occur until a COMMIT command is executed.
B. The table will be removed from the catalog but the data will remain in storage.
C. The table will be removed from the catalog and the data will be deleted.
D. Data will be marked as deleted but still recoverable with Time Travel.
E. An error will occur because Delta Lake prevents the deletion of production data.

Answer: C

Explanation:
When a table is dropped in Delta Lake, the table is removed from the catalog and the data is deleted. This is because Delta Lake is a transactional storage layer that provides ACID guarantees. When a table is dropped, the transaction log is updated to reflect the deletion of the table and the data is deleted from the underlying storage. Reference:

NEW QUESTION # 85
Newly joined data analyst requested read-only access to tables, assuming you are owner/admin which section of Databricks platform is going to facilitate granting select access to the user

A. Data explorer
B. Azure Databricks control pane IAM
C. Azure RBAC
D. Admin console
E. User settings

Answer: A

Explanation:
Explanation
Anser is Data Explorer
https://docs.databricks.com/sql/user/data/index.html
Data explorer lets you easily explore and manage permissions on databases and tables. Users can view schema details, preview sample data, and see table details and properties. Administrators can view and change owners, and admins and data object owners can grant and revoke permissions.
To open data explorer, click Data in the sidebar.

NEW QUESTION # 86
A data engineer needs to install the PyYAML Python package for YAML file processing within their Databricks environment. However, the Databricks workspace is air-gapped and does not have direct internet access to download packages from PyPI. The engineer has already downloaded the required PyYAML wheel ( .whl ) file onto their laptop. The data engineer wants to install the PyYAML package from the local wheel file so that it is automatically available whenever any new cluster is provisioned in their Databricks workspace. Which approach should the data engineer use?

A. Upload the PyYAML.whl file under the data engineer's user home directory in the Workspace, and create a cluster-scoped init script that executes %pip install /path/to/PyYAML.whl on the shared cluster.
B. Add the PyYAML.whl file directly to Databricks Git Repos and assume that any cluster linked to the Repo will automatically have PyYAML installed from that file.
C. Upload the PyYAML.whl file to a Unity Catalog volume. Add the path to the Unity Catalog allowlist if required. Then create a cluster-scoped init script that executes pip install /path/to/PyYAML.whl .
D. Set up a private PyPI repository, register the wheel there, and create a cluster-scoped init script that executes /databricks/python/bin/pip install --index-url=https://{repo-url} PyYAML on the cluster.

Answer: C

Explanation:
Databricks documents that libraries and init scripts can be sourced from Unity Catalog volumes, and for standard access mode, relevant paths can require Unity Catalog allowlist configuration. Databricks also documents that init scripts run on every cluster startup, which is the mechanism that makes a package automatically available whenever a new cluster is provisioned. ( Databricks Documentation ) Option A fits the air-gapped requirement because it does not depend on internet access and uses a startup-time installation mechanism. Option B still depends on reachable repository infrastructure. Option C is incorrect because %pip is notebook magic, not the correct form inside an init script. Option D is unsupported because storing a wheel in Git Repos does not automatically install it on cluster creation. ( Databricks Documentation )
