Microsoft DP-700 Practice Test 1

Question 1

Another workspace owns a trusted Delta table, and duplicate physical storage is prohibited. What should the engineer implement first to satisfy the stated need?

  1. Create an internal OneLake shortcut to the table.
  2. Use Delta transactional writes and retry genuine write conflicts appropriately.
  3. Create a pipeline Copy activity into the destination.
  4. Join facts to reference rows by stable product key.

Explanation

Correct Answer

A:

Shortcuts reference existing OneLake data without copying files.

Incorrect Answers

B:

Delta transaction logs protect supported concurrent operations.

C:

Copy handles scalable source-to-target data movement.

D:

Enrichment joins add trusted attributes from matching keys.

Question 2

Spark aggregates millions of rows after collecting all data into the notebook driver. Which action best addresses the requirement?

  1. Use a skew-aware join plan or carefully designed salting.
  2. Use high-concurrency Spark sessions for compatible workloads.
  3. Move aggregation into distributed Spark expressions.
  4. Assign a smaller compatible environment or pool size.

Explanation

Correct Answer

C:

Distributed aggregation avoids huge driver memory use.

Incorrect Answers

A:

Redistribution prevents one worker from becoming a straggler.

B:

Session reuse reduces startup overhead.

D:

Right-sizing reduces unused capacity while retaining required latency.

Question 3

In a Microsoft Fabric solution, a B2B guest assigned to a OneLake role cannot obtain expected access despite correct table permissions. Which configuration or implementation should the engineer choose?

  1. Reduce broad workspace access and rely on narrowly scoped item and data roles.
  2. Check external collaboration and guest-access configuration in Microsoft Entra.
  3. Provide a valid connection and source-side permissions for the external shortcut.
  4. Assign a managed Microsoft Entra group to the OneLake security role.

Explanation

Correct Answer

B:

Guest identity settings can prevent OneLake role grants from being applied as expected.

Incorrect Answers

A:

Workspace access can confer item-wide rights that undermine fine-grained data access goals.

C:

The target storage system and shortcut credentials must authorize the requested read.

D:

OneLake security resolves supported Entra group membership for role grants.

Question 4

In a Microsoft Fabric solution, several notebook activities within the same Fabric pipeline start separate Spark sessions even though the team wants them to reuse execution capacity. Which configuration or implementation should the engineer choose?

  1. Review the workspace's current domain assignment in the Fabric domain settings.
  2. Publish a Fabric environment with the common library and attach it to the notebooks.
  3. Enable high-concurrency mode for pipeline-running notebooks in workspace Spark settings.
  4. Allow item-level compute customization in workspace Spark pool settings.

Explanation

Correct Answer

C:

The pipeline-specific setting permits compatible notebook activities invoked by pipelines to share a Spark session.

Incorrect Answers

A:

Inspecting the existing association identifies the correct scope before reassigning governance ownership.

B:

Environment items centrally define reusable libraries and Spark runtime settings.

D:

An administrator must enable item-level overrides before an environment's pool and driver settings can be edited.

Question 5

A bronze feed must load at 06:00 in a particular business time zone every working day. Which engineering decision is most suitable for this specific situation?

  1. Invoke the reusable pipeline through an Execute Pipeline activity.
  2. Configure failure notifications on the scheduled pipeline run.
  3. Expose the business date as a pipeline parameter and supply it at invocation.
  4. Create a time-zone-aware recurring schedule for the Fabric pipeline.

Explanation

Correct Answer

D:

A schedule triggers runs based on configured dates, frequency, and time zone.

Incorrect Answers

A:

Child pipelines allow shared orchestration logic without cloning all activities.

B:

Scheduled pipelines support configured failure notifications distinct from manual invocation.

C:

A runtime parameter separates job logic from each run's effective processing date.

Question 6

Eventhouse ingestion accepts JSON but incorrectly maps an event-time field to a string property. What should the engineer implement first to satisfy the stated need?

  1. Correct the event subject filter to match the actual file path and event type.
  2. Correct the Eventhouse ingestion mapping to the intended timestamp column and type.
  3. Update the column reference or apply an explicit rename mapping to the new schema.
  4. Correct the Copy mapping and type conversions for the affected columns.

Explanation

Correct Answer

B:

Ingestion mapping aligns payload paths with typed target fields.

Incorrect Answers

A:

Event-based triggers fire only for events satisfying configured matching conditions.

C:

A missing field name cannot be resolved by the Spark analyzer.

D:

Data type mismatch occurs at mapping or insert even when connectivity succeeds.

Question 7

In a Microsoft Fabric solution, a finance intern needs to read reports in a workspace but must not create notebooks or edit Fabric items. Which configuration or implementation should the engineer choose?

  1. Apply the approved sensitivity label to the item.
  2. Assign a managed Microsoft Entra group to the OneLake security role.
  3. Assign the intern the Viewer workspace role.
  4. Maintain the specific item share rather than granting workspace Contributor.

Explanation

Correct Answer

C:

Viewer can consume workspace content without create or modify privileges.

Incorrect Answers

A:

Sensitivity labels classify and govern sensitive information independently of workspace membership.

B:

OneLake security resolves supported Entra group membership for role grants.

D:

Item access is narrower than workspace roles and avoids unnecessary creation and modification rights.

Question 8

A Fabric Warehouse query plan warns that an operation is non-scalable, and the engineer has confirmed that the query does not semantically require global sorting or other single-node execution. Which single implementation most directly meets the stated requirement?

  1. Push WHERE and aggregate logic into the Warehouse SQL query.
  2. Refresh or correct relevant optimizer statistics.
  3. Use an appropriate shared location or shortcut instead of redundant full copies.
  4. After conventional query tuning, test OPTION (FORCE DISTRIBUTED PLAN) and compare the results and plan.

Explanation

Correct Answer

D:

The FORCE DISTRIBUTED PLAN hint can direct eligible workloads toward distributed execution when single-node processing is not required by query semantics. The direct validation would be: The optimized plan uses distributed operators rather than the previous avoidable single-node stage, with unchanged result rows.

Incorrect Answers

A:

Server-side filtering reduces network and client load.

B:

Statistics influence SQL optimization decisions.

C:

Virtualized access avoids avoidable data movement.

Question 9

A group of users can open a lakehouse item but should read only a selected subset of tables through OneLake. What should the engineer implement first to satisfy the stated need?

  1. Reduce broad workspace access and rely on narrowly scoped item and data roles.
  2. Review supported audit events for role and permission changes.
  3. Maintain the specific item share rather than granting workspace Contributor.
  4. Create a OneLake security role granting Read on the selected tables.

Explanation

Correct Answer

D:

OneLake roles scope data permissions within the item and deny access to ungranted objects.

Incorrect Answers

A:

Workspace access can confer item-wide rights that undermine fine-grained data access goals.

B:

Audit logs provide available governance activity history for investigation.

C:

Item access is narrower than workspace roles and avoids unnecessary creation and modification rights.

Question 10

A finance team rotates employees frequently and does not want to maintain hundreds of direct OneLake role members. Which engineering decision is most suitable for this specific situation?

  1. Assign the release lead the Member workspace role.
  2. Review supported audit events for role and permission changes.
  3. Assign a managed Microsoft Entra group to the OneLake security role.
  4. Check external collaboration and guest-access configuration in Microsoft Entra.

Explanation

Correct Answer

C:

OneLake security resolves supported Entra group membership for role grants.

Incorrect Answers

A:

Member includes item management and sharing without full Admin workspace deletion privileges.

B:

Audit logs provide available governance activity history for investigation.

D:

Guest identity settings can prevent OneLake role grants from being applied as expected.
