Microsoft PL-300 Practice Test 3

Question 20

A manufacturing dashboard must reflect database transactions nearly immediately and policy forbids persisting source rows inside Power BI. Which action is most appropriate for the stated business outcome?

  1. Use Direct Lake over the supported Fabric tables.
  2. Connect to the approved shared Power BI semantic model.
  3. Import the ledger into a Power BI semantic model.
  4. Connect to the relational source using DirectQuery.

Explanation

Correct Answer

D:

DirectQuery sends supported visual queries to the source instead of storing imported fact rows, supporting live operational data without model caching.

Incorrect Answers

A:

Direct Lake reads underlying Delta data using the tabular engine and avoids a conventional full import duplicate. It would address querying lakehouse Delta tables directly, not live operational data without model caching.

B:

Reusing the shared semantic model centralizes metric definitions and existing managed relationships. That targets reporting on governed enterprise measures, not live operational data without model caching.

C:

Import materializes compressed data in the model and queries it without contacting the operational source on each interaction. It may suit low-latency cached historical analytics, not live operational data without model caching.

Question 21

A finance analyst needs to ingest all CSV extracts placed each night into one local directory with a uniform schema. Which step should the analyst take?

  1. Use the Folder connector and Combine Files workflow.
  2. Use the OData Feed connector with the service URL.
  3. Use the SQL Server database connector with approved authentication.
  4. Use the SharePoint Online List connector.

Explanation

Correct Answer

A:

Folder enumeration and sample-file transformation combine consistently shaped files, supporting combining recurring local extract files.

Incorrect Answers

B:

The OData connector consumes the endpoint's metadata and entity navigation surface. Its scope is acquiring OData service entities, not combining recurring local extract files.

C:

The database connector supports relational schema browsing and model loading or DirectQuery. That is meant for accessing a managed SQL operational database, not combining recurring local extract files.

D:

The list connector retrieves list item fields and metadata instead of pretending the list is a file. It would address loading structured SharePoint list items, not combining recurring local extract files.

Question 22

A vendor endpoint issues a scoped API token and explicitly documents header-key authentication for its dataset. Which action is most appropriate for the stated business outcome?

  1. Configure organizational-account OAuth authentication for the supported connector.
  2. Use the connector's supported Web API credential mode and protected key storage.
  3. Choose the supported Windows authentication mode and gateway identity.
  4. Use Anonymous authentication only for the approved public endpoint.

Explanation

Correct Answer

B:

The Web API credential mechanism supplies an authorized API key without embedding it in query text, supporting protected API-key authentication.

Incorrect Answers

A:

Organizational OAuth uses user or service identity tokens instead of pasting anonymous keys. It would address delegated enterprise identity authentication, not protected API-key authentication.

C:

Windows authentication uses an approved directory context for the internal database. It may suit integrated corporate database access, not protected API-key authentication.

D:

Anonymous mode avoids sending unnecessary secrets to a source designed for public reads. It is useful for permitted unauthenticated catalog reads, not for protected API-key authentication.

Question 23

An internal shared reference list can be combined with other organizational data under the organization's policy. Which step should the analyst take?

  1. Reenable privacy-level enforcement and correct source-specific classifications.
  2. Mark the payroll source Private in Power Query source privacy settings.
  3. Assign Organizational privacy level to the approved internal source.
  4. Assign Public privacy level to that public source.

Explanation

Correct Answer

C:

Organizational privacy permits compatible combinations within the trusted organization boundary, supporting controlled internal source combination.

Incorrect Answers

A:

Ignoring privacy restrictions can allow query behavior that transmits restricted values to another source. It is useful for restoring privacy isolation after unsafe bypass, not for controlled internal source combination.

B:

Private isolation limits folding and combining that could expose protected source values to another endpoint. Its scope is isolate confidential payroll during data combination, not controlled internal source combination.

D:

Public sources are permitted to contribute data to higher-trust mashups without treating their values as secrets. It would address appropriately classify open-source information, not controlled internal source combination.

Question 24

The same report must point to development and production SQL servers when promoted between environments. Which action is most appropriate for the stated business outcome?

  1. Configure the parameter's data type and allowed values appropriately.
  2. Update the published semantic model's parameter values and applicable credentials.
  3. Create a Power Query year parameter and reference it in the source transformation.
  4. Parameterize server and database names and set environment-appropriate values.

Explanation

Correct Answer

D:

Source parameters separate environment configuration from the transformation logic, supporting changing SQL endpoints safely across environments.

Incorrect Answers

A:

Typed and constrained parameters reduce invalid query argument combinations. It would address safe parameter value validation, not changing SQL endpoints safely across environments.

B:

Published parameters and credential configuration are managed in the service independently of the local file. That targets correct service-side production parameter values, not changing SQL endpoints safely across environments.

C:

A parameter provides a typed reusable input to multiple query expressions. It may suit reusable year input in Power Query, not changing SQL endpoints safely across environments.

Question 25

An office-hosted SQL Server sits on a private subnet unreachable from the Power BI service. Which step should the analyst take?

  1. Install and configure an on-premises data gateway with approved data source mappings.
  2. Deploy a supported gateway cluster with redundant members.
  3. Migrate to an on-premises data gateway in standard mode with delegated administration.
  4. Configure the supported cloud connection without an unnecessary on-premises gateway.

Explanation

Correct Answer

A:

The gateway brokers service refresh traffic to internal network sources, supporting refresh from isolated corporate SQL.

Incorrect Answers

B:

A gateway cluster can distribute requests and provide availability when a member fails. Its scope is resilient enterprise gateway access, not refresh from isolated corporate SQL.

C:

Standard gateway supports shared enterprise data source administration beyond one user's personal gateway. That is meant for centrally administered gateway reuse, not refresh from isolated corporate SQL.

D:

A public cloud source supported by native service connectivity can refresh without on-premises tunneling. It would address direct managed cloud refresh, not refresh from isolated corporate SQL.

Question 26

A DirectQuery visual sends hundreds of requests to its source because a user scrubs a slicer continuously. Which action is most appropriate for the stated business outcome?

  1. Configure incremental refresh with RangeStart and RangeEnd filter parameters.
  2. Introduce supported query-reduction or Apply controls for high-interaction filters.
  3. Configure automatic page refresh within capacity and source limits.
  4. Increase semantic model scheduled refresh frequency within its license and source limits.

Explanation

Correct Answer

B:

Query reduction delays or consolidates source requests rather than firing on every intermediate selection, supporting limit DirectQuery filter-query bursts.

Incorrect Answers

A:

Incremental refresh partitions historical and changing rows to avoid full reprocessing. It would address partition refresh by changing date window, not limit DirectQuery filter-query bursts.

C:

Automatic page refresh updates eligible DirectQuery pages on a defined interval. It may suit recurring real-time page updates, not limit DirectQuery filter-query bursts.

D:

Refresh schedules determine when import data is reloaded from sources. It is useful for align Import freshness with business cadence, not for limiting DirectQuery filter-query bursts.

Question 27

A report refresh fails with expired OAuth credentials although its source URL is valid. Which step should the analyst take?

  1. Map the semantic model to the correct gateway connection and data source.
  2. Change the source endpoint in Power Query data source settings.
  3. Update the source credentials in the relevant Power BI connection settings.
  4. Clear permissions for the old data source and reauthenticate only when authorized.

Explanation

Correct Answer

C:

Refresh authentication is separate from the source address and cached data; this helps repair expired cloud credentials.

Incorrect Answers

A:

Service refresh requires matching connection paths and authentication mappings. It is useful for fixing published model gateway binding, not for repair expired cloud credentials.

B:

Connection settings can be updated without rebuilding later transform steps. Its scope is retain transformations after server relocation, not repair expired cloud credentials.

D:

Clearing source permissions removes stored credential bindings for that endpoint. It would address remove obsolete stored source credentials, not repair expired cloud credentials.

Question 28

A flat file contains accented names but the imported text displays replacement characters. Which action is most appropriate for the stated business outcome?

  1. Parse JSON and expand the list and nested records in Power Query.
  2. Use the Web connector's detected table or supported HTML table selection.
  3. Use the CSV connector with the correct delimiter and quoting rules.
  4. Set the source text encoding to the file's actual character set.

Explanation

Correct Answer

D:

Correct code-page decoding preserves Unicode and legacy encoded characters, supporting decode supplier text correctly.

Incorrect Answers

A:

JSON navigation and expansion converts hierarchical payloads to tabular columns. It would address flatten structured JSON records, not decode supplier text correctly.

B:

Table extraction selects semantic rows and columns from supported web content. That targets retrieve tabular website data, not decode supplier text correctly.

C:

Delimiter and quotation parsing prevents embedded separators from splitting one logical field. It may suit preserve quoted CSV field boundaries, not decode supplier text correctly.

Question 29

A report performs text manipulation using a custom function and then struggles to fold subsequent filters. Which step should the analyst take?

  1. Move supported foldable filters before the nonfolding custom transformation.
  2. Inspect View Native Query and query-folding indicators for the selected step.
  3. Stage an approved shared reference result and control query evaluation rather than duplicate repeated API calls.
  4. Filter rows near the source step while preserving query folding.

Explanation

Correct Answer

A:

Filter order can preserve upstream database pushdown before an operation prevents further folding; this helps avoid breaking query folding too early.

Incorrect Answers

B:

Query folding indicators and native statements expose pushdown behavior where supported. Its scope is verify relational query folding, not avoid breaking query folding too early.

C:

Reusing a controlled source evaluation may reduce repeated requests when supported by the refresh plan. That is meant for manage rate-limited API request duplication, not avoid breaking query folding too early.

D:

Folded filtering delegates predicates to the database and reduces transferred rows. It would address push restricted date filters to SQL, not avoid breaking query folding too early.

Question 30

Employees submit a structured change log through Microsoft Lists rather than document files. Which action is most appropriate for the stated business outcome?

  1. Use the SharePoint Folder connector and filter to the desired library path.
  2. Use the SharePoint Online List connector for the hosted list.
  3. Use the supported authenticated file or SharePoint connection for that workbook.
  4. Connect to the governed published semantic model rather than reading underlying site files anew.

Explanation

Correct Answer

B:

List-specific connectors retrieve structured list entries and columns, supporting ingest Microsoft Lists rows.

Incorrect Answers

A:

The SharePoint Folder connector enumerates files from site libraries and can combine standard workbook content. It would address combine library-hosted workbook files, not ingest Microsoft Lists rows.

C:

File-scoped connections can retrieve the specified file without scanning every unrelated folder. It may suit connect to one secured cloud workbook, not ingest Microsoft Lists rows.

D:

Shared semantic models preserve upstream governed measures and row security. It is useful for reuse central analytics objects rather than raw files, not for ingest Microsoft Lists rows.
