PL-300 Practice Test 6 — 10 Questions

Question 1

Which TWO are valid ways to distribute a Power BI report to users who do not have Power BI Pro licenses?

Accepted Answer

Embed the report in a Power BI app with Premium capacity.. Options B and C are correct. Power BI Premium capacity allows reports to be shared with users who do not have Power BI Pro licenses. Embedding a report in a Power BI app (Option B) within a Premium capacity workspace grants access to free users. Publishing a report to a workspace backed by Premium capacity (Option C) enables sharing with free users. Option A is incorrect because Power BI service sharing requires the recipient to have a Pro or Premium per user license. Option D is incorrect because exporting to PDF does not bypass license requirements; the user must still have appropriate access. Option E is incorrect because publishing to web makes the report public, which is not a controlled distribution method for non-Pro users.

Answer

Share the report via Power BI service sharing.

Answer

Export the report as PDF and email it.

Answer

Publish to web (public).

Question 2

You are a Power BI administrator. A user reports that their scheduled data refresh fails with error 'The data source credentials are no longer valid.' The dataset uses a SQL Server database with Windows authentication. What should you do first to resolve the issue?

Accepted Answer

Ask the user to update the data source credentials in the Power BI service dataset settings.. The error 'The data source credentials are no longer valid' typically occurs when the password has changed or expired. The user can update the credentials in the dataset settings in the Power BI service. Option A is incorrect because the on-premises data gateway is not the issue; a reinstall is unnecessary. Option B is incorrect because reassigning the dataset to a different Premium capacity does not address credential validity. Option C is incorrect because using 'Impersonate the authenticated user' still requires valid credentials and does not fix the problem.

Answer

Reinstall the on-premises data gateway on the server.

Answer

Reassign the dataset to a different Premium capacity.

Answer

Modify the dataset to use 'Impersonate the authenticated user' for data sources.

Question 3

You need to ensure that a Power BI report published to the service can be embedded in a secure internal SharePoint Online page. Only authenticated users from your Microsoft Entra ID tenant should be able to view the report. What should you do?

Accepted Answer

Use the 'Embed in SharePoint Online' option in Power BI service.. To embed a Power BI report securely in a SharePoint Online page, use the 'Embed in SharePoint Online' option in the Power BI service. This generates a secure embed link that respects Microsoft Entra ID authentication and permissions, ensuring only authorized users can view the report. After generating the link, add the Power BI web part to a SharePoint page and paste the link. Option B is incorrect because sharing a direct link does not embed the report; it only provides a hyperlink. Option C is incorrect because 'Publish to web' makes the report publicly accessible without authentication. Option D is also a method that generates a secure embed code, but the 'Embed in SharePoint Online' option is the most straightforward and recommended approach for SharePoint embedding, making Option A the correct choice.

Answer

Share the report directly with all users and provide a direct link.

Answer

Use the 'Publish to web (public)' option and embed the iframe in SharePoint.

Answer

Use the 'Embed' option in Power BI service to generate a secure embed code, then add the Power BI web part in SharePoint.

Question 4

Which THREE components must be in place to enable Power BI data sensitivity labels from Microsoft Purview? (Select exactly three.)

Accepted Answer

Power BI admin setting to enable sensitivity labels enabled. Options A, B, and D are correct. To enable Power BI data sensitivity labels from Microsoft Purview, three components are needed: the Power BI admin setting to enable sensitivity labels must be turned on (A), sensitivity labels must be published to users or groups in the Microsoft Purview compliance portal (B), and a Microsoft Purview Information Protection subscription (including Azure Information Protection P1/P2) is required (D). Option C is incorrect because Power BI Premium capacity is not a prerequisite; sensitivity labels work with both Power BI Pro and Premium capacities. Option E is incorrect because a Power BI Pro license is not required for all users; the feature can be used with any license type if the admin enables it and the necessary subscriptions are in place.

Answer

Power BI Premium capacity assigned to the workspace

Answer

Power BI Pro license for all users

Question 5

You have a Power BI dataset that uses a DirectQuery connection to Azure Synapse Analytics. Users report that the report is slow. You need to improve query performance without changing the data source. What should you do?

Accepted Answer

Reduce the number of visuals on each report page.. Reducing the number of visuals on each report page reduces the number of queries sent to the data source, improving performance for DirectQuery datasets. Option A is incorrect because reducing cardinality of measures may reduce data size but does not directly reduce the number of queries. Option B is incorrect because disabling RLS could change data access but does not significantly improve query performance. Option C is incorrect because increasing scheduled refresh frequency applies to import mode, not DirectQuery.

Answer

Reduce the cardinality of calculated measures.

Answer

Disable row-level security (RLS) on the dataset.

Answer

Increase the scheduled refresh frequency.

Question 6

A company is deploying Power BI for the entire organization. They need to prevent users from sharing reports with external email addresses. Which configuration should the Power BI admin use?

Accepted Answer

Disable 'Share content with external users' in the Power BI admin portal.. The Power BI admin portal provides a tenant-level setting 'Share content with external users' that can be disabled to prevent sharing with external email addresses. Option B is incorrect because Conditional Access policies in Microsoft Entra ID control access based on conditions but do not specifically block external sharing within Power BI. Option C is incorrect because Microsoft Purview sensitivity labels classify and protect data but do not block sharing. Option D is incorrect because workspace sharing settings only control sharing within the workspace and do not prevent external sharing at the tenant level.

Answer

Configure a Conditional Access policy in Microsoft Entra ID.

Answer

Apply a Microsoft Purview sensitivity label.

Answer

Set the workspace sharing settings to 'Only existing users'.

Question 7

Your organization uses Microsoft Purview Information Protection to label sensitive data in Power BI datasets. You need to ensure that when a report is exported to Excel, the sensitivity label is automatically applied. What should you configure?

Accepted Answer

Ensure the dataset has a sensitivity label and that the export inherits the label.. When a Power BI dataset has a sensitivity label applied via Microsoft Purview Information Protection, any downstream exports (such as reports exported to Excel) automatically inherit that label. This inheritance ensures consistent protection across all outputs. Option D is incorrect because the Power BI admin portal setting 'Apply sensitivity labels to exported data' is used to apply labels when the data source does not have a label, but it does not override automatic inheritance from a labeled dataset. Option B is incorrect because DLP policies in Microsoft Purview monitor and protect data, but they do not automatically apply sensitivity labels to exports. Option C is incorrect because setting a default sensitivity label on a report is not a feature; sensitivity labels are inherited from the dataset, not configured per report.

Answer

Use data loss prevention (DLP) policies in Microsoft Purview.

Answer

Set a default sensitivity label on the report.

Answer

Enable 'Apply sensitivity labels to exported data' in the Power BI admin portal.

Question 8

A Power BI report uses a DirectQuery data source. The model includes a calculated column that uses the RELATED function to bring a value from another table. The report is performing slowly. What design change would most improve performance without compromising functionality?

Accepted Answer

Replace the calculated column with a calculated table that includes the related column.. Replacing the calculated column with a calculated table that includes the related column moves the join logic to query time, reducing the per-row overhead of the RELATED function in DirectQuery mode. In DirectQuery, calculated columns are evaluated row-by-row for each query, which can cause significant performance degradation; a calculated table is materialized once during refresh (or in DirectQuery, it is resolved as a single query to the source), avoiding repeated row-level lookups. This change preserves the functionality of having the related value available in the table while improving query performance.

Answer

Remove the RELATED function and merge tables in the source query.

Answer

Convert the model to Import mode.

Answer

Use a measure instead of a calculated column.

Question 9

Your organization uses Power BI Premium and wants to enforce that users can only see data relevant to their department (Sales, Marketing, Finance) using row-level security (RLS). The dataset contains a 'Department' column. You have created three RLS roles, each with a filter like [Department] = "Sales". You publish the dataset and add users to the roles. However, users in the Sales role can see all data. What is the most likely cause?

Accepted Answer

The users are also assigned to workspace roles (e.g., Member) that grant them access to the dataset without RLS restrictions.. In Power BI, users assigned to workspace roles (Admin, Member, Contributor) have dataset-level permissions that bypass Row-Level Security (RLS). Since these users can access the dataset directly, RLS filters are not applied. Option A is incorrect because RLS roles are typically created in Power BI Desktop before publishing. Option B is incorrect; multiple roles combine filters using OR logic, so users in multiple roles see union of all allowed data, not all data. Option C is incorrect because RLS filters are case-insensitive by default. Option D correctly identifies that workspace roles override RLS.

Answer

The RLS roles were created in the Power BI service, not in Power BI Desktop.

Answer

The users are members of multiple RLS roles, so they see all data.

Answer

The RLS filter uses a string comparison that is case-sensitive and the data contains mixed case.

Question 10

Which TWO of the following are valid methods to share a Power BI report with external users (outside your organization)? (Choose two.)

Accepted Answer

Invite the external user as a guest in your Microsoft Entra ID (Azure AD) and share the report directly with them.. The correct answers are C and E. Option C: By inviting external users as guests in your Microsoft Entra ID (Azure AD) using Azure AD B2B, you can share Power BI reports directly with them without requiring them to have a Power BI license. Option E: 'Publish to web' creates a public embed code that anyone on the internet can view, making it suitable for sharing with external users. Option A is incorrect because exporting to PDF creates a static file, not an interactive report, and is not a sharing method. Option B is incorrect because external users need to be set up as guests or use publish to web; a direct link alone will not work without proper authentication. Option D is incorrect because embedding in SharePoint Online requires the external user to have access to the SharePoint site, which typically involves additional setup such as guest access.

Answer

Export the report to PDF and email it to the external user.

Answer

Send the external user a direct link to the report via email; they can view it without any additional setup.

Answer

Embed the report in a SharePoint Online page using the Power BI web part.
