Core Power BI Interview Questions & Expert Model Answers

- What are the major differences between visual-level, page-level, and report-level filters in Power BI?
Answer:- Visual-level filters apply only to a single visualization.
- Page-level filters affect all visuals on a specific report page.
- Report-level filters apply across every page and all visuals in the report.
- How do you optimize Power BI data models for performance?
Answer: Use a star schema, avoid unnecessary bi-directional relationships, prefer measures over calculated columns, and aggregate data at the source before loading. - Explain Row-Level Security (RLS) and its implementation.
Answer: RLS restricts data visibility based on user roles. Define roles with DAX (e.g.,[Region] = USERPRINCIPALNAME()) in Power BI Desktop, then assign users to these roles in the Power BI Service. - What is Power BI Gateway and why is it important?
Answer: The Gateway connects on-premises data sources (like SQL Server) to the Power BI Cloud, enabling scheduled dataset refreshes and secure data transfer. - How do you create dynamic report titles based on filter selections?
Answer: Use a DAX measure withSELECTEDVALUE()and concatenate your title. Display in a Card visual for a dynamic effect.
