Note: This question is a part of a series of questions that present the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
Start of repeated scenario
You have a Microsoft SQL Server database that contains the following tables.
The following columns contain data information:
– Date[Month] in the mmyyyy format
– Date[Date_ID] in the ddmmyyyy format
– Date[Date_name] in the mm/dd/yyyy format
– Monthly_returns[Month_ID] in the mmyyyy format
The Order table contains more than one million rows.
The Store table has relationship to the Monthly_returns table on the Store_ID column. This is the only relationship between the tables.
You plan to use Power BI desktop to create an analytics solution for the data.
End of repeated scenario.
You are modifying the model to report on the number of order.
You need to calculate the number of orders.
What should you do?
- A . Create a calculated measure that uses the COUNTA(Order_ID) DAX formula.
- B . Create a calculated measure that uses the SUM (Order_ID) DAX formula.
- C . Create a calculated column that uses the SUM (Order_ID) DAX formula.
- D . Create a calculated column that uses the COUNTA (Order_ID) DAX formula.

End of repeated scenario.
You plan to create a chart that displays total Order [Order_amount] by Store [Name].
You need to modify the model to ensure that you can create the chart.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A . To the Order table, add a column that uses the RELATED(‘Store’ [Store_ID]) DAX formula.
- B . Create a relationship between the Order table and the Store table.
- C . To the Order table, add a measure that uses the COUNT (‘Order’[Order_amount]) DAX formula.
- D . To the order table, add a measure that uses the SUM (‘Order’ [Order_amount]) DAX formula.

End of repeated scenario.
You need to configure a KPI indicator to show the monthly sales of a store versus the target sales of the store.
How should you configure the KPI indicator? To answer, drag the appropriate column to the correct fields. Each column 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.
You plan to use Power BI Desktop to create a report. The report will consume data from an on-premises tabular named SalesDB in Microsoft SQL Server Analysis Services (SSAS). The report will be published to the Power BI service.
You need to ensure that the report published to the Power BI service will access the current data in SalesDB.
What should you do?
- A . Deploy an on-premises data gateway and configure the connection to SalesDB to use the Import Data Connectivity mode.
- B . Deploy an on-premises data gateway and configure the connection to SalesDB to use the Connect live option.
- C . Deploy an on-premises data gateway (personal mode) and configure to SalesDB to use the DirectQuery Data Connectivity mode.
- D . Deploy an on-premises data gateway and configure the connection to SalesDB to use the DirectQuery Data Connectivity mode.

You have a column named phone_number. The values in the columns are in one of the following formats:
– 999-999-9999×123
– 1-999-999-9999×232
– +1-999-999-9999x66x666
The values after x in the phone-number column indicate the phone extension.
You need to create a custom column in Query Editor that contains only the phone extensions.
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.
