The answer is that users assigned to workspace roles like Member, Contributor, or Admin bypass row-level security restrictions. This occurs because workspace-level permissions grant direct access to the dataset’s underlying data, overriding any RLS filters applied at the role level. In Power BI, RLS only restricts data for users who access reports through the app or shared dashboards without explicit dataset permissions—if a user has a workspace role that allows them to view or edit the dataset, the security filters are ignored entirely. On the PL-300 exam, this scenario tests your understanding of the hierarchy between workspace permissions and RLS, often appearing as a trick where candidates assume the RLS role syntax is faulty. A common trap is forgetting that workspace Members can see all data regardless of RLS. Memory tip: think “Workspace role trumps RLS role”—if they can see the dataset, they see everything.
PL-300 Manage and secure Power BI Practice Question
This PL-300 practice question tests your understanding of manage and secure power bi. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The users are also assigned to workspace roles (e.g., Member) that grant them access to the dataset without RLS restrictions.
Option B is correct because if the users have workspace-level permissions that allow them to see all data (e.g., Admin, Member, Contributor), RLS is bypassed. Option A is wrong because the filter syntax is correct. Option C is wrong because RLS works in Power BI Desktop preview. Option D is wrong because multiple roles don't cause this issue; they are additive.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The RLS roles were created in the Power BI service, not in Power BI Desktop.
Why it's wrong here
RLS roles can be created in Desktop and then applied in the service.
✗
The users are members of multiple RLS roles, so they see all data.
Why it's wrong here
Multiple roles combine, but if one role restricts to Sales, they should only see Sales data from that role.
✗
The RLS filter uses a string comparison that is case-sensitive and the data contains mixed case.
Why it's wrong here
DAX string comparisons are case-insensitive by default.
✓
The users are also assigned to workspace roles (e.g., Member) that grant them access to the dataset without RLS restrictions.
Why this is correct
Users with edit permissions on the dataset bypass RLS.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Variation 1. Refer to the exhibit. You are reviewing a DAX expression used in a Power BI measure. You need to ensure that only users in the 'West' region see data for that region. Which approach should you use?
easy
✓ A.Implement row-level security (RLS) in the dataset with a role filter.
B.Use the CALCULATE function with a filter on the report page.
C.Modify the measure to include a conditional statement that checks the user's email.
D.Create a calculated column with the same logic.
Why A: Option C is correct because the DAX expression is a measure that calculates the sum for the 'West' region, but it does not restrict data for other users. To enforce security, you need to implement row-level security (RLS) by adding a filter in the dataset roles. Option A is wrong because you cannot restrict the measure to specific users directly. Option B is wrong because the measure itself calculates for West only, but RLS is needed for security. Option D is wrong because the measure is already specific to West.
