Sample Practice Questions
Question 1: You are tasked with creating a Star Schema in Power BI. You have a massive sales table and several smaller lookup tables for Products, Dates, and Stores. What is the recommended relationship cardinality between the 'Products' table and the 'Sales' table?
A. Many-to-many (:)
B. One-to-one (1:1)
C. One-to-many (1:*) from Products to Sales
D. One-to-many (1:*) from Sales to Products
E. Many-to-one (*:1) from Products to Sales
F. None; these tables should not be related in a Star Schema.
Correct Answer: C
Explanation:
C (Correct): In a standard Star Schema, the dimension table (Products) sits on the "one" side, and the fact table (Sales) sits on the "many" side to ensure efficient filtering and data integrity.
A (Incorrect): Many-to-many relationships introduce complexity and performance hits; they should be avoided unless absolutely necessary for specific bridge-table scenarios.
B (Incorrect): One-to-one relationships usually imply that the data could simply be merged into a single table.
D (Incorrect): This reverses the logical flow of a Star Schema where a single product can appear many times in sales.
E (Incorrect): While logically similar, Power BI relationship notation specifically defines the direction from the Dimension (1) to the Fact (*).
F (Incorrect): Relationships are the foundation of Power BI data modeling.
Question 2: You need to ensure that a specific report page only displays data for the "North America" region without allowing users to change this selection via a slicer. Which filter scope should you use?
A. Visual-level filter
B. Page-level filter
C. Report-level filter
D. Drill-through filter
E. Filtered URL parameters
F. DAX Calculated Column
Correct Answer: B
Explanation:
B (Correct): A page-level filter applies to every visual on that specific page and can be locked or hidden from the end-user in the Filter Pane.
A (Incorrect): This would only affect a single visual, requiring you to repeat the process for every chart on the page.
C (Incorrect): This would filter the entire report, including other pages that might need to show different regions.
D (Incorrect): Drill-through is used for navigating between pages based on a specific data point, not for static page filtering.
E (Incorrect): URL parameters are for external navigation and are less secure/permanent than pane filters.
F (Incorrect): A calculated column creates new data but does not inherently control the visibility of existing data on a canvas.
Question 3: Which Power BI Service feature should you use to provide a single-page view of the most critical metrics from five different reports?
A. Power BI App
B. Power BI Workspace
C. Power BI Dashboard
D. Power BI Paginated Report
E. Power BI Dataflow
F. Power BI Gateway
Correct Answer: C
Explanation:
C (Correct): Dashboards are designed to "pin" visuals from multiple underlying reports into a single, high-level overview.
A (Incorrect): An App is a distribution method for a collection of reports and dashboards, not the visualization canvas itself.
B (Incorrect): A Workspace is a container for collaboration, not a viewing tool for consolidated metrics.
D (Incorrect): Paginated reports are for print-ready, pixel-perfect layouts, usually for operational lists rather than high-level metrics.
E (Incorrect): Dataflows are used for data preparation and ETL processes.
F (Incorrect): A Gateway is for connecting cloud reports to on-premises data sources.
