PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A retail company uses Power BI to analyze sales data. They want to allow store managers to view their own store's sales but not other stores. Which Power BI feature should they implement?
⚠ Common exam trap
Candidates often confuse data filtering in Power Automate (which operates on triggers and actions) with the declarative, role-based filtering of RLS, or they mistakenly think embedding tools like Power Apps can enforce security, when in fact RLS is the only native Power BI feature for row-level data access control.
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
✓
Row-level security (RLS)
Row-level security (RLS) in Power BI allows you to restrict data access for specific users based on roles and filters. By defining a role that filters sales data by store ID and assigning store managers to that role, each manager can only see their own store's sales, meeting the requirement without duplicating reports or data.
