Explanation:

The required outcome is to ensure that the Power BI service can connect to the database and refresh the semantic model. The completed mapping shown in the answer area is correct. A broader role would grant unnecessary authoring or administration, while Viewer cannot create or publish workspace content.
Workspace access is role based. Viewer is read-only, Contributor can create and publish content, Member adds broader collaboration rights, and Admin can manage the workspace and its users. The current skills outline describes this competency as " Identify when a gateway is required " . This keeps service access and operational behavior within the scope requested instead of granting or changing unrelated capabilities.
