  1. Question 1 of 10

    What is the top-level container in the Unity Catalog three-level namespace?

    1. AA file path
    2. BA catalog
    3. CA schema
    4. DA volume
    Show the answer

    A catalog establishes the highest organization and isolation boundary; schemas and volumes occupy the second and third levels.

    Next → 1 / 10

  2. Question 2 of 10

    What is the second-level container that groups related Unity Catalog objects?

    1. AA workspace binding
    2. BA metastore region
    3. CA managed file
    4. DA schema
    Show the answer

    A schema sits inside a catalog and groups related tables, views, volumes, and functions; the other choices are not the second namespace level.

    Next → 2 / 10

  3. Question 3 of 10

    Which object governs nontabular files with a `catalog.schema.object` identity?

    1. AAn instance pool
    2. BA volume
    3. CA SQL warehouse
    4. DA compute policy
    Show the answer

    A volume is the third-level Unity Catalog object for governed files; the distractors configure or supply compute instead of file governance.

    Next → 3 / 10

  4. Question 4 of 10

    Which privilege pair is required on a parent catalog to create a schema?

    1. AUSE SCHEMA and CREATE VOLUME
    2. BREAD VOLUME and WRITE VOLUME
    3. CUSE CATALOG and CREATE SCHEMA
    4. DCREATE CATALOG and CAN RESTART
    Show the answer

    Schema creation occurs inside an existing catalog, so the creator must use that catalog and have permission to create schemas there.

    Next → 4 / 10

  5. Question 5 of 10

    What happens when an external volume is dropped?

    1. AThe external location becomes a managed volume automatically
    2. BThe cloud files are marked for deletion after seven days
    3. CThe parent schema and catalog are deleted with the files
    4. DThe Unity Catalog registration is removed and the cloud files remain
    Show the answer

    An external volume governs an existing location without owning its file lifecycle, so DROP removes registration only; the seven-day deletion behavior belongs to managed volumes.

  7. Question 6 of 10

    Which path correctly addresses a file inside a Unity Catalog volume?

    1. A`/Volumes/landing/sales/bronze/orders.csv`
    2. B`/Volumes/sales/bronze/landing/orders.csv`
    3. C`/Schemas/sales/bronze/landing/orders.csv`
    4. D`/Catalogs/sales/landing/bronze/orders.csv`
    Show the answer

    The volume path orders the namespace as catalog, schema, then volume before the file path: sales, bronze, landing, and orders.csv.

    Next → 6 / 10

  8. Question 7 of 10

    Where do managed objects store data when a schema has its own managed location?

    1. AAt the catalog location regardless of schema settings
    2. BInside the workspace file system without governance
    3. CAt a new external volume
    4. DAt the schema-level managed location
    Show the answer

    The schema location overrides the catalog location for managed objects in that schema; fallback occurs only when the schema has no managed location.

    Next → 7 / 10

  9. Question 8 of 10

    A production catalog needs dedicated storage and access from only production workspaces. Managed objects in its schemas should inherit that storage unless a schema overrides it. Which design best fits?

    1. ACreate a schema with no catalog and bind it directly to workspaces
    2. BCreate one volume and use its READ VOLUME grant as the catalog boundary
    3. CCreate the catalog with managed storage and restrict its workspace bindings
    4. DUse a file-name prefix and leave the catalog accessible to all workspaces
    Show the answer

    A catalog supports the required top-level storage, isolation, access policy, and workspace-binding boundary, while schemas can inherit or override its managed location.

    Next → 8 / 10

  10. Question 9 of 10

    A legacy application and Azure Databricks must keep using the same model files at an existing cloud path. Governance must be added, and deleting the Unity Catalog object must not delete those files. Which object should be created?

    1. AA managed catalog with no volume
    2. BA managed volume in the schema's storage
    3. CA schema-level information schema
    4. DAn external volume over the existing path
    Show the answer

    An external volume adds Unity Catalog governance to existing storage while leaving file lifecycle outside Unity Catalog, satisfying both continued access and deletion constraints.

    Next → 9 / 10

  11. Question 10 of 10

    Two file groups share a schema but require different readers. Both groups need governed `/Volumes` paths, and subdirectory ACLs are unavailable. Which design meets the access requirement?

    1. ACreate one volume and grant READ VOLUME on selected folders
    2. BCreate one volume and use file-name casing as an access boundary
    3. CCreate one external location and rely on WRITE VOLUME for readers
    4. DCreate two volumes and grant READ VOLUME separately
    Show the answer

    Volume permissions cover the entire volume, so separate volumes create the required security boundaries while retaining the standard governed path.
