PL-300 Power BI workspace roles Practice Question
Which TWO are valid Power BI workspace roles?
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
✓
Viewer
In Power BI, the four valid workspace roles are Admin, Member, Contributor, and Viewer, so option A (Viewer) is correct because it grants read-only access to view reports and dashboards without editing content, and option B (Admin) is correct because it provides full control of the workspace including adding/removing users, managing permissions, and deleting the workspace. Option C (Owner) is not a Power BI workspace role—ownership concepts apply to items or capacities, not workspace membership roles. Option D (Reader) is not a workspace role; read-only access is provided by the Viewer role. Option E (Editor) is not a workspace role; edit permissions are granted via Contributor, Member, or Admin roles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Viewer
Why this is correct
Viewer is a legitimate read-only workspace role in Power BI. Viewers can see and interact with dashboards, reports, and apps in the workspace, but they cannot edit content, share items, or manage permissions. This role is ideal for consumers who only need to view and analyze data without modifying the underlying reports.
- ✓
Admin
Why this is correct
Admin is the highest valid workspace role with full control over the workspace. Admins can edit, share, add or remove other members, assign roles, and even delete the workspace itself. The creator of a new workspace automatically becomes an Admin, and this role maps to the 'Owner' concept conceptually, but 'Admin' is the exact role name in Power BI.
- ✗
Owner
Why it's wrong here
Owner is not a distinct, valid workspace role in the Power BI role system. While the person who creates a workspace is functionally the owner, they are automatically assigned the Admin role, not an 'Owner' role. Power BI only exposes Admin, Member, Contributor, and Viewer, so selecting 'Owner' would be incorrect in any role-assignment scenario.
- ✗
Reader
Why it's wrong here
Reader is not a valid workspace role in Power BI; the actual read-only role is called Viewer. The term 'Reader' might be confused with Viewers or with database/OneDrive reader concepts, but Power BI workspace permissions rely on the four specific role names, and Reader is not among them. Using 'Reader' would not grant any meaningful access in an app workspace.
- ✗
Editor
Why it's wrong here
Editor is not a recognized workspace role in Power BI's current role architecture. The roles that allow content editing are Member and Contributor, but neither is named 'Editor'. This common misnomer likely arises from other collaboration tools, but in Power BI you must assign the Contributor or Member role to someone who needs to edit or publish content within a workspace.
