You have an Azure subscription that contains an Azure Databricks workspace. The workspace contains a notebook named Notebook1.

In Notebook1, you create an Apache Spark DataFrame named df_sales that contains the following columns:

• Customer
• SalesPerson
• Region
• Amount

You need to identify the three top performing salespersons by amount for a region named HQ.

How should you complete the query? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.
