A production workload runs many quick SQL queries on a warehouse that frequently sits idle and costs more than expected.
Which acceptance result most directly demonstrates that the intended solution works?
Compute lifecycle and concurrency settings influence cost independently of individual SQL correctness.
The analysis identifies the first slow run and correlates it to a particular task or source-size change. That finding does not establish that idle-hour spend decreases while representative query startup latency remains acceptable.
The root failing upstream task is reproduced and fixing it unblocks the Gold task. That finding does not establish that idle-hour spend decreases while representative query startup latency remains acceptable.
After a targeted plan change shuffle bytes and elapsed stage time decrease without changing results. That finding does not establish that idle-hour spend decreases while representative query startup latency remains acceptable.
A team creates a Unity Catalog managed Delta table and wants Databricks to manage its backing data files and lifecycle.
Which implementation decision best addresses this requirement?
Managed tables place storage lifecycle under the managed table service instead of treating files as independently owned external data. The selected implementation is the one directly aligned with the constraints in the scenario.
External table definitions reference externally managed files; dropping the table does not have the same data deletion semantics as dropping a managed table.
An external table points to data outside managed table storage and requires appropriate external location access.
Unity Catalog table read access generally requires the relevant catalog and schema usage permissions plus object SELECT.

Which acceptance result most directly demonstrates that the intended solution works?
Managed tables place storage lifecycle under the managed table service instead of treating files as independently owned external data.
After the metadata is removed, the original external files remain available at their approved location. That finding does not establish that the table is registered as managed and its storage is governed by the platform's managed-table lifecycle.
The external table queries the existing files without relocating them into an unrelated managed directory. That finding does not establish that the table is registered as managed and its storage is governed by the platform's managed-table lifecycle.
The analyst queries the approved table after all three required privilege levels are present. That finding does not establish that the table is registered as managed and its storage is governed by the platform's managed-table lifecycle.
An engineer plans to drop a Unity Catalog external table but must keep the source objects available to another processing system.
Which implementation decision best addresses this requirement?
External table definitions reference externally managed files; dropping the table does not have the same data deletion semantics as dropping a managed table. The selected implementation is the one directly aligned with the constraints in the scenario.
Managed storage lets the platform control the physical location and lifecycle of the table data.
Managed versus external classification involves lifecycle and location semantics, not merely a display label.
Least-privilege access separates querying rows from modifying data or managing security.

Which acceptance result most directly demonstrates that the intended solution works?
External table definitions reference externally managed files; dropping the table does not have the same data deletion semantics as dropping a managed table.
A new managed table appears in the target schema and can be queried with its three-part name. That finding does not establish that after the metadata is removed, the original external files remain available at their approved location.
The migrated managed table reads the same validated records and its storage lifecycle is managed as intended. That finding does not establish that after the metadata is removed, the original external files remain available at their approved location.
The BI user can SELECT but an attempted INSERT or UPDATE is refused. That finding does not establish that after the metadata is removed, the original external files remain available at their approved location.
A data platform team wants to create a curated Delta table in a governed catalog without choosing or maintaining an explicit object-storage path.
Which implementation decision best addresses this requirement?
Managed storage lets the platform control the physical location and lifecycle of the table data. The selected implementation is the one directly aligned with the constraints in the scenario.
An external table points to data outside managed table storage and requires appropriate external location access.
Creating objects referencing external storage requires the relevant storage governance rights as well as schema privileges.
Creation rights and existing-table read rights are distinct securable privileges.

The external table queries the existing files without relocating them into an unrelated managed directory. That finding does not establish that a new managed table appears in the target schema and can be queried with its three-part name.
The authorized principal creates the external table in the permitted path and is denied outside it. That finding does not establish that a new managed table appears in the target schema and can be queried with its three-part name.
The engineer creates a table in the approved schema but cannot create objects in unrelated schemas. That finding does not establish that a new managed table appears in the target schema and can be queried with its three-part name.
An organization already owns Parquet and Delta files in an approved external bucket and wants Databricks metadata to reference them without moving ownership.
Which implementation decision best addresses this requirement?
An external table points to data outside managed table storage and requires appropriate external location access. The selected implementation is the one directly aligned with the constraints in the scenario.
Managed versus external classification involves lifecycle and location semantics, not merely a display label.
Unity Catalog table read access generally requires the relevant catalog and schema usage permissions plus object SELECT.
Unity Catalog distinguishes data-modification rights from read-only SELECT and scope can be narrowed to the required table.

The pipeline can perform its permitted write operation while readers cannot modify records. That finding does not establish that the external table queries the existing files without relocating them into an unrelated managed directory.
A migration converts a previously external-managed dataset into a managed table and engineers assume that changing a catalog flag alone will relocate every byte.
Which implementation decision best addresses this requirement?
Managed versus external classification involves lifecycle and location semantics, not merely a display label. The selected implementation is the one directly aligned with the constraints in the scenario.
Creating objects referencing external storage requires the relevant storage governance rights as well as schema privileges.
Least-privilege access separates querying rows from modifying data or managing security.
REVOKE removes specified grants, but effective access can remain through other memberships or inherited privileges.
