- A
RLS is not supported in shared capacity; you need a Premium license.
Why wrong: Incorrect. RLS is supported in shared capacity; no Premium license needed.
- B
RLS roles must be created in the Power BI service after publishing; they cannot be created in Power BI Desktop.
Why wrong: Incorrect. RLS roles can be created in Power BI Desktop.
- C
RLS cannot be applied when the dataset uses DirectQuery to a data source that requires single sign-on (SSO) because the user's identity is passed through, and the source must enforce RLS.
Correct. With DirectQuery and SSO, user identity passes to the source, so RLS must be enforced in the source.
- D
RLS can only be applied to tables that are imported, not to tables using DirectQuery.
Why wrong: Incorrect. RLS can be applied to DirectQuery tables, but with SSO the source enforces it.
PL-300 Row-Level Security (RLS) 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. A key principle to apply: row-Level Security (RLS). 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 with a shared capacity (no Premium capacity). You need to implement row-level security (RLS) on a dataset that is used by multiple reports. Which of the following is a limitation you must consider?
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
RLS cannot be applied when the dataset uses DirectQuery to a data source that requires single sign-on (SSO) because the user's identity is passed through, and the source must enforce RLS.
Option C is correct because when using DirectQuery with single sign-on (SSO), the user's identity is passed directly to the data source, and Power BI's RLS cannot override it. The source itself must enforce RLS. Option A is incorrect because RLS is fully supported in shared capacity without a Premium license. Option B is incorrect because RLS roles can be created in Power BI Desktop before publishing. Option D is incorrect because RLS can be applied to both imported tables and DirectQuery tables, though with SSO, the source must enforce RLS.
Key principle: Row-Level Security (RLS)
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
RLS is not supported in shared capacity; you need a Premium license.
Why it's wrong here
Incorrect. RLS is supported in shared capacity; no Premium license needed.
- ✗

Why this is correct
Correct. With DirectQuery and SSO, user identity passes to the source, so RLS must be enforced in the source.

Row-Level Security (RLS)
- ✗
RLS can only be applied to tables that are imported, not to tables using DirectQuery.
Why it's wrong here
Incorrect. RLS can be applied to DirectQuery tables, but with SSO the source enforces it.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The key trap is that while RLS works with DirectQuery in general, when SSO is enabled, the user's identity flows to the source, and Power BI's RLS cannot filter rows—the source must handle security.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

TExam Day Tips
- 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
Row-Level Security (RLS)
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.
