Microsoft DP-700 Practice Test 47

Question 460

A pipeline Copy activity returns HTTP 401 immediately after a source credential rotation. Which observation most directly verifies the intended outcome after the appropriate action?

  1. Run inputs show the intended resolved path and the source file is found.
  2. A rerun authenticates and begins reading source rows with the approved identity.
  3. Previously rejected fixture rows land with valid target types and values.
  4. A rerun succeeds with least-privilege permissions and no repeated 403s.

Explanation

Correct Answer

B:

Successful source access confirms credential repair. This observation directly tests the expected outcome.

Incorrect Answers

A:

Effective path plus file discovery validates the correction.

C:

Row-level type checks confirm mapping alignment.

D:

Permission and run evidence verify the root fix.

Question 461

An engineer needs to create and edit pipelines in a workspace but must not manage membership. Which postchange result provides the strongest validation of success?

  1. The Viewer uploads a file to the allowed folder but cannot write elsewhere.
  2. An unauthorized identity cannot execute the procedure while authorized users can.
  3. The contractor can open the shared warehouse but not unrelated workspace items.
  4. The engineer can save pipeline changes but cannot add workspace members.

Explanation

Correct Answer

D:

Successful editing with denied membership administration proves the intended role boundary. This observation directly tests the expected outcome.

Incorrect Answers

A:

Testing both folder paths verifies the scope of delegated writes.

B:

Execution tests under both identities verify the object permission boundary.

C:

Testing both the permitted and unrelated item exposes accidental broad grants.

Question 462

Consider this Microsoft Fabric case: A pipeline is initiated by a storage event but manually testing its event-file-name expression returns null. What measured result demonstrates that the requirement is satisfied?

  1. The initial and existing-file test runs execute different branches as designed.
  2. Manual runs handle absent event fields gracefully while event-triggered runs resolve the file name.
  3. A matching file creation causes one relevant pipeline run, while nonmatching files do not.
  4. The run creates one child activity execution for each returned file.

Explanation

Correct Answer

B:

Success in both invocation modes validates the null-handling logic. This observation directly tests the expected outcome.

Incorrect Answers

A:

Observed branch selection proves the condition is evaluated correctly.

C:

Matched and filtered-out test events validate the trigger predicate.

D:

Iteration count and per-file inputs validate dynamic fan-out.

Question 463

A compliance administrator needs OneLake API and file access diagnostic events to land in a governed diagnostics lakehouse, but no OneLake diagnostics destination is configured in the Fabric workspace. The engineer implements this change: enable diagnostic events in workspace OneLake settings and select the approved diagnostic lakehouse. Which observed result would provide the most direct evidence that the change achieved its intended goal?

  1. The development Airflow job starts when needed and its Starter pool is automatically shut down after the supported idle period.
  2. The owner can manage that domain's workspace assignments without tenant-wide administrative privileges.
  3. The two compatible notebooks attach to the same active high-concurrency Spark session without starting a second Spark application.
  4. New supported OneLake operations create diagnostic records in the selected lakehouse with the expected operation metadata.

Explanation

Correct Answer

D:

A verified newly generated diagnostics record demonstrates that event capture and destination routing are active. It specifically confirms the result of this change: Enable diagnostic events in workspace OneLake settings and select the approved diagnostic lakehouse.

Incorrect Answers

A:

Both on-demand execution and idle deprovisioning confirm that the workspace is using the intended cost-conscious pool behavior. It does not establish the required result, which is: New supported OneLake operations create diagnostic records in the selected lakehouse with the expected operation metadata.

B:

A scope-limited successful domain operation demonstrates least privilege. It does not establish the required result, which is: New supported OneLake operations create diagnostic records in the selected lakehouse with the expected operation metadata.

C:

The shared Spark session ID, rather than notebook success alone, demonstrates reuse of execution capacity. It does not establish the required result, which is: New supported OneLake operations create diagnostic records in the selected lakehouse with the expected operation metadata.

Question 464

Consider this Microsoft Fabric case: A Fabric pipeline repeatedly retries an unrecoverable 403 permission error and wastes its execution window. What measured result demonstrates that the requirement is satisfied?

  1. A rerun authenticates and begins reading source rows with the approved identity.
  2. Gateway status is healthy and a fresh dataflow read succeeds.
  3. A rerun succeeds with least-privilege permissions and no repeated 403s.
  4. The run's effective parameter values resolve before activities execute.

Explanation

Correct Answer

C:

Permission and run evidence verify the root fix. This observation directly tests the expected outcome.

Incorrect Answers

A:

Successful source access confirms credential repair.

B:

Connectivity evidence isolates the gateway problem.

D:

Input inspection verifies the binding.

Question 465

A KQL query has become slow and support needs to compare execution characteristics across revisions. What should the engineer check to confirm that the intended behavior was achieved?

  1. The slow stage appears with disproportionately high execution duration.
  2. The slow request appears with its session and elapsed state during execution.
  3. Incoming-event or ingestion counters advance after a test event.
  4. Slow and baseline executions have comparable inputs but differing resource or duration evidence.

Explanation

Correct Answer

D:

Controlled comparisons validate a query regression. This observation directly tests the expected outcome.

Incorrect Answers

A:

Granular timing identifies the actual hot spot.

B:

A live DMV record establishes the query-level bottleneck.

C:

Eventhouse-side counts validate reception. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: Slow and baseline executions have comparable inputs but differing resource or duration evidence.

Question 466

A large Spark fact joins a tiny lookup dimension that fits executor memory. Which observation most directly verifies the intended outcome after the appropriate action?

  1. Physical plan uses broadcast and shuffle bytes decrease.
  2. Actual session resources change and spill metrics improve.
  3. Shuffle bytes fall and grouped results remain equal.
  4. Physical copies decrease and consumers still read current data.

Explanation

Correct Answer

A:

Plan and bytes verify the mechanism. This observation directly tests the expected outcome.

Incorrect Answers

B:

Resource and execution evidence confirm tuning.

C:

Execution evidence validates the rewrite.

D:

Storage plus parity validate simplification.

Question 467

An Apache Airflow job in a production Fabric workspace runs frequent business-critical DAGs and must avoid the automatic idle shutdown of the default Starter pool. The engineer implements this change: create and assign a Custom Apache Airflow pool through the workspace Data Factory Apache Airflow Runtime Settings. Which observed result would provide the most direct evidence that the change achieved its intended goal?

  1. New supported OneLake operations create diagnostic records in the selected lakehouse with the expected operation metadata.
  2. The two compatible notebooks attach to the same active high-concurrency Spark session without starting a second Spark application.
  3. That notebook resolves its dedicated environment while other notebooks still resolve Workspace default.
  4. The production DAG uses the configured Custom pool, which remains running through an idle period without being automatically shut down as a Starter pool.

Explanation

Correct Answer

D:

The job pool assignment and continued pool availability directly verify the requirement for continuously provisioned production scheduling. It specifically confirms the result of this change: Create and assign a Custom Apache Airflow pool through the workspace Data Factory Apache Airflow Runtime Settings.

Incorrect Answers

A:

A verified newly generated diagnostics record demonstrates that event capture and destination routing are active. It does not establish the required result, which is: The production DAG uses the configured Custom pool, which remains running through an idle period without being automatically shut down as a Starter pool.

B:

The shared Spark session ID, rather than notebook success alone, demonstrates reuse of execution capacity. It does not establish the required result, which is: The production DAG uses the configured Custom pool, which remains running through an idle period without being automatically shut down as a Starter pool.

C:

The different effective bindings prove configuration isolation. It does not establish the required result, which is: The production DAG uses the configured Custom pool, which remains running through an idle period without being automatically shut down as a Starter pool.

Question 468

Sales analysts share one warehouse table but each analyst should query only rows for the regions assigned to that identity. Which observation most directly verifies the intended outcome after the appropriate action?

  1. An unauthorized identity cannot execute the procedure while authorized users can.
  2. After the approved guest-access policy change, the guest's authorized data query succeeds.
  3. Different analyst identities querying the same table obtain only their authorized regional rows.
  4. An analyst can select allowed columns but receives an authorization error for Salary.

Explanation

Correct Answer

C:

Identity-specific row sets directly test the filtering predicate. This observation directly tests the expected outcome.

Incorrect Answers

A:

Execution tests under both identities verify the object permission boundary.

B:

Guest-specific test confirms identity prerequisites, not only role membership.

D:

Denied access to the protected column demonstrates enforcement.

Question 469

Dense device telemetry must support near-real-time filtering and KQL investigation. Which observation most directly verifies the intended outcome after the appropriate action?

  1. Synthetic events yield the expected service-window counts.
  2. Recent source events are queryable with expected event timestamps.
  3. Matched and unmatched fixture keys produce expected outcomes.
  4. Structured tables are queryable and reconcile with source files.

Explanation

Correct Answer

B:

Freshness and record correspondence test the design. This observation directly tests the expected outcome.

Incorrect Answers

A:

Bucket reconciliation verifies correct time grouping.

C:

Join-key reconciliation validates semantics. That observation may be useful elsewhere, but it does not directly confirm the expected evidence in the case: Recent source events are queryable with expected event timestamps.

D:

Table registration and row correspondence confirm transformation.

Question 470

A mirrored operational database already supplies source updates into Fabric. What should the engineer check to confirm that the intended behavior was achieved?

  1. Committed versions show consistent data with no partial corrupt writes.
  2. A new source update appears in Fabric without an extra scheduled copy.
  3. After refresh, the new field appears without shifting older columns.
  4. The file folder is listed while no unintended query table appears.

Explanation

Correct Answer

B:

Live change observation verifies reuse. This observation directly tests the expected outcome.

Incorrect Answers

A:

Transaction history and row checks demonstrate integrity.

C:

Old and new column mappings both reconcile.

D:

The registration boundary matches the requirement.
