The correct answer is that row-level security can be defined using DAX filter expressions, is applied when the user queries the dataset, and does not apply to the XMLA endpoint by default unless dynamic security is configured. RLS works by evaluating DAX filter rules at query time, restricting data based on the user’s identity before any visual renders, which means the filters are enforced on all visuals—not selectively. On the PL-300 exam, this concept tests your understanding of how RLS differs from role-based access; a common trap is assuming RLS applies to the XMLA endpoint automatically or that it can be toggled per visual. Remember the key distinction: RLS is user-based, not role-based, and dynamic security requires a DAX expression like `USERNAME()` to map users to data. A helpful memory tip is “RLS = Row-Level, not Role-Level”—the filter is always on the row, never on the visual.
PL-300 Model the data Practice Question
This PL-300 practice question tests your understanding of model the data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE of the following are considerations when implementing row-level security (RLS) in Power BI? (Select three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
RLS does not apply to data accessed via the XMLA endpoint unless using dynamic security.
Options A, C, and E are correct. RLS is applied when the user queries the dataset (A). It can be defined using DAX filters (C). It does not apply to the XMLA endpoint by default unless dynamic (E). Option B is incorrect because RLS filters apply to all visuals. Option D is incorrect because RLS is user-based, not role-based in terms of dynamic security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
RLS does not apply to data accessed via the XMLA endpoint unless using dynamic security.
Why this is correct
Static RLS is not enforced via XMLA; dynamic security is needed.

RLS filters are applied at query time.
Why this is correct
Filters are applied dynamically when the user accesses the report.

✓
RLS can be defined using DAX filter expressions.
Why this is correct

✗
RLS is enforced only for users with the Viewer role.
Why it's wrong here
RLS is enforced for all users regardless of workspace role.
✗
RLS can be bypassed by using the 'Show all' option in visuals.
Why it's wrong here
RLS cannot be bypassed by users.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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. Which THREE considerations are important when implementing row-level security (RLS) in Power BI? (Select exactly 3.)
hard
✓ A.Roles can use DAX expressions to define filters
✓ B.RLS can filter data based on the user's identity
C.RLS is automatically applied when using Analyze in Excel
✓ D.RLS in DirectQuery mode pushes filters to the source database
E.RLS can restrict access to specific measures
Why A: Options A, B, and D are correct. Option A: RLS filters data at the row level based on the user's role. Option B: Roles can be defined using DAX expressions that filter tables. Option D: RLS is enforced in DirectQuery mode, but performance depends on the source. Option C is wrong because RLS does not restrict access to measures; measures are still visible unless explicitly hidden. Option E is wrong because RLS is not applied when users view data in Power BI Desktop; it is only applied when published to the service.
