PL-300 Manage and secure Power BI Practice Question
Your organization uses Microsoft Purview to catalog Power BI assets. You need to ensure that all published reports and dashboards are automatically scanned and added to the catalog. What should you do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Register the Power BI tenant as a data source in Microsoft Purview.
The correct option is A: register the Power BI tenant as a data source in Microsoft Purview. Microsoft Purview scans and catalogs Power BI assets (reports, dashboards, datasets, dataflows) only after the Power BI tenant is registered as a data source and a scan is configured, which uses the Power BI Admin API and requires tenant-level read-only admin permissions. Option B is unrelated: enabling Microsoft Entra ID authentication in the Power BI admin portal does not trigger Purview scanning or cataloging. Option C, applying sensitivity labels, governs data protection and classification but does not populate the Purview catalog with Power BI assets. Option D is incorrect because creating a workspace and assigning a catalog admin role does not register the tenant or initiate scanning of published reports and dashboards.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Register the Power BI tenant as a data source in Microsoft Purview.
Why this is correct
Registering the Power BI tenant as a data source in Microsoft Purview is the essential first step because it establishes a connection from Purview Data Map to your organization's Power BI environment. Once registered, Purview automatically scans and catalogs metadata from all workspaces, datasets, dataflows, reports, and dashboards without requiring manual asset entry. This registration typically requires a Power BI administrator role so Purview can authenticate and retrieve the metadata.
- ✗
Enable 'Allow Microsoft Entra ID authentication' in the Power BI admin portal.
Why it's wrong here
The 'Allow Microsoft Entra ID authentication' setting in the Power BI admin portal governs whether users can authenticate to Power BI resources using AAD credentials. It is a tenant-level authentication control that does not create or register any data source in Microsoft Purview, nor does it trigger any scanning or cataloging of Power BI assets. Cataloging requires a Purview-specific registration action, not an authentication toggle.
- ✗
Apply sensitivity labels to all assets.
Why it's wrong here
Applying sensitivity labels to all assets classifies and protects your Power BI content based on Microsoft Information Protection policies, but it does not automatically add those assets to the Purview catalog. Sensitivity labels are metadata tags that Purview can read, but the catalog scan must already be set up for Purview to discover assets in the first place. In other words, labeling improves governance after assets are cataloged, but it cannot initiate the cataloging process itself.
- ✗
Create a new workspace in Power BI and assign the catalog admin role.
Why it's wrong here
Creating a new Power BI workspace and assigning a so-called 'catalog admin' role cannot register the tenant with Purview because workspace roles in Power BI are limited to Admin, Member, Contributor, and Viewer—there is no 'catalog admin' role. Even if such a role existed, workspaces are containers for content, not data sources; scanning in Purview is performed at the Power BI tenant level, not per workspace. Therefore, this action has no effect on Purview catalog scanning.
