Topic #: 3
You have a Power BI data model that contains a table named Employees. The table has the following columns:
; Employee Name
; Email Address
; Start Date
; Job Title
You are implementing dynamic row-level security (RLS).
You need to create a table filter to meet the following requirements:
; Users must see only their own employee data
; The DAX expression must work in both Power BI Desktop and the Power BI service.
Which expression should you use?
; Employee Name
; Email Address
; Start Date
; Job Title

Suggested Answer: C Vote an answer
The technical decision turns on how to filter Employees so each signed-in user sees the row whose Email Address matches that user ' s principal name. The supported selection is C ([Email Address] = USERPRINCIPALNAME()). Dynamic RLS can compare a model column with USERPRINCIPALNAME(), which returns the signed-in user ' s user principal name in both Power BI Desktop and the service. The comparison must use Email Address, not Employee Name. USERNAME() can vary by environment, and comparing a principal name with an employee display name uses incompatible identity values. The current PL-300 study guide places this under the objective " Implement row-level security roles " . This keeps service access and operational behavior within the scope requested instead of granting or changing unrelated capabilities.
