Microsoft PL-300 Practice Test 6

Question 50

A published semantic model refresh fails because an on-premises database is unreachable after a firewall change. What is the MOST appropriate Power BI design decision?

  1. Validate upstream warehouse load timestamps and source freshness SLAs.
  2. Fix the conversion or error-handling step for invalid numeric source values.
  3. Inspect and correct the Power Query date-filter step.
  4. Repair gateway network connectivity and the permitted database route.

Explanation

Correct Answer

D:

Gateway refresh needs reachable internal endpoints and supported network permissions; this helps restore private database refresh connectivity.

Incorrect Answers

A:

A successful Power BI refresh cannot invent source updates that have not yet arrived. It would address distinguish stale source data from refresh failure, not restore private database refresh connectivity.

B:

Type conversion errors occur when raw values cannot be parsed as the specified type. That targets repair numeric conversion during refresh, not restore private database refresh connectivity.

C:

Source query filters determine which records enter the loaded model. It may suit recover unintentionally filtered historical rows, not restore private database refresh connectivity.

Question 51

A report designer needs to publish a personal experimental table that must not change an established semantic model. Which configuration should the team choose?

  1. Create a separate governed development semantic model for the experiment.
  2. Reuse that semantic model with its existing RLS and permission assignments.
  3. Build reports against the certified shared semantic model.
  4. Create or reuse an approved Power BI dataflow for repeatable upstream transformations.

Explanation

Correct Answer

A:

Separate development assets prevent unapproved changes to certified enterprise metrics, supporting isolate experimental model changes.

Incorrect Answers

B:

A connected report can inherit semantic-model security rather than recreate rules independently. Its scope is preserve governed data-access semantics, not isolate experimental model changes.

C:

Central models keep shared measures and relationships under one steward. That is meant for consistent enterprise KPI reuse, not isolate experimental model changes.

D:

Dataflows centralize Power Query transformation logic for multiple downstream consumers. It would address reusable data preparation across reports, not isolate experimental model changes.

Question 52

A Lakehouse Delta dataset needs Fabric capacity-backed access without a full data import. What is the MOST appropriate Power BI design decision?

  1. Choose DirectQuery if the source meets responsiveness requirements.
  2. Use supported Direct Lake semantics over the Lakehouse tables.
  3. Connect to the approved Power BI semantic model.
  4. Use an Import model refreshed before the outage.

Explanation

Correct Answer

B:

Direct Lake is optimized for underlying OneLake Delta storage when its supported conditions are met, supporting analytical access to OneLake storage.

Incorrect Answers

A:

DirectQuery reads current source records during visual evaluation subject to source latency. It would address near-live source evaluation, not analytical access to OneLake storage.

C:

Semantic model sharing avoids redefining measures, model relationships, and security configuration. It may suit reuse DAX measure definitions, not analytical access to OneLake storage.

D:

Import keeps compressed rows available without a live database connection during interaction. It is useful for offline report analysis during source outage, not for analytical access to OneLake storage.

Question 53

A temporary vendor should stop accessing a dataflow after a contract expires. Which configuration should the team choose?

  1. Configure approved least-privileged source credentials or a managed connection.
  2. Use an approved application identity and scoped consent where the connector supports it.
  3. Remove the vendor's relevant item or workspace access and review any downstream sharing.
  4. Inspect the configured connection credentials and authentication identity in service settings.

Explanation

Correct Answer

C:

Access removal terminates permissions independently of data source refresh settings, supporting revoke expiring collaborator authorization.

Incorrect Answers

A:

Least-privileged source identities reduce risk of broad database control. It is useful for limiting refresh credential privilege, not for revoke expiring collaborator authorization.

B:

Workload identity separates unattended service access from personal user credentials. Its scope is protected unattended API access, not revoke expiring collaborator authorization.

D:

Credential configuration determines the security context used when fetching source rows. It would address audit identity used during data refresh, not revoke expiring collaborator authorization.

Question 54

A report should accept a controlled set of region choices rather than arbitrary server names. What is the MOST appropriate Power BI design decision?

  1. Reference one reusable numeric parameter in the relevant queries.
  2. Use a database-name parameter referenced by each relevant Power Query.
  3. Change the parameter type to Date or DateTime and align column comparisons.
  4. Restrict a Power Query parameter to its list of allowed region values.

Explanation

Correct Answer

D:

Suggested or fixed permitted values constrain deployment configuration to approved regions, supporting restrict dynamic source choices.

Incorrect Answers

A:

Parameter reuse prevents inconsistent hard-coded constants across query steps. It would address consistent parameterized threshold management, not restrict dynamic source choices.

B:

Shared parameters centralize per-environment database selection without editing all scripts. That targets controlled subsidiary source parameterization, not restrict dynamic source choices.

C:

Correctly typed parameters avoid incompatible M comparisons and filter errors. It may suit repair date parameter typing, not restrict dynamic source choices.

Question 55

A CSV import contains duplicated header lines between monthly file blocks. Which configuration should the team choose?

  1. Remove repeated header records before promoting final column headers.
  2. Implement supported pagination logic and validate continuation tokens.
  3. Select the necessary columns in a folding-friendly Power Query step.
  4. Connect to the governed aggregated view instead of raw transaction events.

Explanation

Correct Answer

A:

Cleaning repeated header rows avoids treating captions as business data; this helps correct multi-block flat-file import.

Incorrect Answers

B:

Cursor paging is necessary to collect all result pages under a paginated API contract. Its scope is complete paged API extraction, not correct multi-block flat-file import.

C:

Column projection reduces data transfer and downstream model memory usage. That is meant for trim acquired data to required fields, not correct multi-block flat-file import.

D:

Matching source grain can reduce row volume without losing the needed report detail. It would address select fit-for-purpose source granularity, not correct multi-block flat-file import.

Question 56

A domain expert sends a local Excel workbook as a one-time source for an exploratory PBIX. What is the MOST appropriate Power BI design decision?

  1. Use the Azure SQL database connector with approved credentials.
  2. Use the Excel workbook connector to import the approved sheet or table.
  3. Use supported Direct Lake over Delta tables exposed by the Lakehouse.
  4. Use a connection to the shared semantic model with necessary Build permission.

Explanation

Correct Answer

B:

The Excel connector reads workbook tables and ranges into Power Query, supporting exploratory workbook import.

Incorrect Answers

A:

Azure SQL connectivity retrieves supported tables and queries from the managed relational service. It would address direct Azure SQL ingestion, not exploratory workbook import.

C:

Direct Lake serves supported tabular views over OneLake data without a separate full import. It may suit query Fabric Lakehouse assets directly, not exploratory workbook import.

D:

Build access allows creating content based on an approved semantic model without acquiring raw credentials. It is useful for authorized reuse of shared model, not for exploratory workbook import.

Question 57

An API exposes personal identifiers that the report does not need for its aggregation. Which configuration should the team choose?

  1. Prefer a centrally endorsed or certified semantic model with documented owner.
  2. Reconcile source lineage and the authoritative ledger before loading the final measure.
  3. Exclude unnecessary personal fields at the earliest permitted acquisition step.
  4. Replace ad hoc credentials with an approved service-owned refresh connection.

Explanation

Correct Answer

C:

Data minimization reduces sensitive exposure and model footprint, supporting minimize personally identifying source fields.

Incorrect Answers

A:

Endorsed datasets have a known accountable owner and reviewed metric meaning. It is useful for selecting trusted KPI source, not for minimize personally identifying source fields.

B:

Source-of-truth governance prevents adopting unverified alternate totals. Its scope is resolve competing revenue sources, not minimize personally identifying source fields.

D:

Accountable managed identities reduce orphaned access and make rotation supportable. It would address accountable production connector ownership, not minimize personally identifying source fields.

Question 58

An executive report should reuse an already-governed enterprise metric model without rebuilding its measures and relationships. What is the best method for this analysis requirement?

  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

B:

Reusing the shared semantic model centralizes metric definitions and existing managed relationships, supporting reporting on governed enterprise measures.

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 reporting on governed enterprise measures.

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 reporting on governed enterprise measures.

D:

DirectQuery sends supported visual queries to the source instead of storing imported fact rows. It is useful for live operational data without model caching, not for reporting on governed enterprise measures.

Question 59

A cloud database exposes SQL tables and allows a supported native SQL Server connector with company credentials. Which implementation best addresses this scenario?

  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

C:

The database connector supports relational schema browsing and model loading or DirectQuery, supporting accessing a managed SQL operational database.

Incorrect Answers

A:

Folder enumeration and sample-file transformation combine consistently shaped files. It is useful for combining recurring local extract files, not for accessing a managed SQL operational database.

B:

The OData connector consumes the endpoint's metadata and entity navigation surface. Its scope is acquiring OData service entities, not accessing a managed SQL operational database.

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 accessing a managed SQL operational database.

Question 60

An intentionally public JSON catalog has no identity requirement and should be retrieved without adding account credentials. What is the best method for this analysis requirement?

  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

D:

Anonymous mode avoids sending unnecessary secrets to a source designed for public reads, supporting permitted unauthenticated catalog reads.

Incorrect Answers

A:

Organizational OAuth uses user or service identity tokens instead of pasting anonymous keys. It would address delegated enterprise identity authentication, not permitted unauthenticated catalog reads.

B:

The Web API credential mechanism supplies an authorized API key without embedding it in query text. That targets protected API-key authentication, not permitted unauthenticated catalog reads.

C:

Windows authentication uses an approved directory context for the internal database. It may suit integrated corporate database access, not permitted unauthenticated catalog reads.
