Microsoft Power BI Data Analyst Practice Question

You are preparing data in Power Query for a Power BI report. The query named Sales contains 75 000 transaction rows with a CustomerID column. Another query named Customers contains one row per customer with the same CustomerID key and several demographic columns. You need a single result that preserves the 75 000 sales rows while adding the demographic columns from Customers to each matching transaction. Which action should you perform?

  • Merge Customers with Sales by CustomerID using a Right Anti join.

  • Append the Customers query to the Sales query.

  • Append the Sales query to Customers and then remove duplicates on CustomerID.

  • Merge Sales with Customers by CustomerID using a Left Outer join.
