Example Questions:

Question 1:

You need to create a semantic model in Power BI Desktop. The model must contain a table named Orders with one row per order, containing the total amount per order. Orders must be filtered to the selected CustomerID value, selectable from an OData source. Which Power Query Editor objects should you create?

• Correct Answer: An Orders query with a filter on CustomerID, a Customers query with a filter on CustomerID, and a parameter for CustomerID that uses a query to populate the suggested values.
• Explanation: Filtering the Orders query by CustomerID ensures you only retrieve relevant orders. The Customers query provides the dynamic list of customers from the OData source. The parameter allows users to select a customer, dynamically filtering the Orders query.

Question 2:

You need to configure row-level security (RLS) to restrict data access for users with Viewer permissions. What is the correct sequence of actions?

• Correct Answer: 5-2-4-1-3
• Explanation: First, define the RLS role in Power BI Desktop using a DAX filter. Then, publish the semantic model to the Power BI service. Next, assign users to the RLS role in the Power BI service. Finally, assign the users the Viewer role in the Power BI workspace.

Question 3:

You're refreshing a Power BI report connected to an Excel data source and receive an "Expression.Error: The column ‘Cost’ of the table wasn't found" error. What's the likely cause?

• Correct Answer: The Cost column was renamed in the data source.
• Explanation: This error typically occurs when a column used in Power Query is renamed or removed in the source Excel file. Power Query relies on column names to apply transformations.
