Microsoft Azure Data Fundamentals DP-900 Practice Question
Your Power BI data model includes a Date table with separate Year, Quarter, Month, and Day columns. Report users want to drill down from yearly totals to specific days within a single column chart, without manually adding columns in the visual. Which data-modeling feature should you configure to meet this requirement?
Apply row-level security based on the Date table
Write a DAX measure to return totals at different date levels
Create a hierarchy that contains the Year, Quarter, Month, and Day columns
Define a calculated column that concatenates Year, Quarter, Month, and Day
A hierarchy combines related columns into a single expandable structure. When you add the hierarchy to a visual, Power BI automatically provides drill-down and drill-up actions, letting users move from Year to Quarter, Month, and Day without manually placing each column. A calculated column or DAX measure would not provide interactive drill actions, and row-level security controls data access, not navigation.
