- A
Use Power BI Report Builder to define RLS on paginated reports.
Why wrong: RLS is not defined in Report Builder; it's defined on the dataset.
- B
Create RLS rules directly in the Power BI service under dataset security.
Why wrong: RLS rules are created in Power BI Desktop and then applied in the service after publishing.
- C
Define roles and role members in Power BI Desktop using DAX filter expressions.
This is the primary method to create RLS in Power BI Desktop.
- D
Assign users to security groups in Microsoft Entra ID and map those groups to RLS roles in the Power BI service.
Why wrong: RLS roles in Power BI are not mapped to Entra ID groups directly; members are added to roles in the service.
- E
Configure RLS in the source database when using DirectQuery with single sign-on (SSO).
With SSO, the source can enforce RLS based on the user's identity.
PL-300 Manage and secure Power BI Practice Question
This PL-300 practice question tests your understanding of manage and secure power bi. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 TWO of the following are valid ways to enforce row-level security (RLS) on a Power BI dataset? (Choose two.)
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
Define roles and role members in Power BI Desktop using DAX filter expressions.
Options A and C are correct. RLS can be defined in Power BI Desktop using static roles, and in DirectQuery with SSO, RLS can be enforced in the source database. Option B is wrong because RLS is not applied via the Power BI service interface for datasets; it's defined in Desktop. Option D is wrong because RLS in Power BI is not based on Microsoft Entra ID groups; it's based on roles defined in the model. Option E is wrong because RLS is not configured in Excel.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why this is correct
With SSO, the source can enforce RLS based on the user's identity.
Related concept

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PL-300 NAT questions on configuration and troubleshooting.
