You have a Power BI model that contains the following tables:
* Sales (Sales_ID, DateID, sales_amount)
* Date (DateID, Date, Month, week, Year)
The tables have a relationship. Date is marked as a date table in the Power BI model.
You need to create a measure to calculate the sales for the last 12 months.
Which DAX formula should you use?

• A.SUM(sales[sales_amount])-CALCULATE(SUM(sales[sales_amount]),
  SAMEPERIODLASTYEAR('Date'[Date]))
• B.SUM(sales[sales_amount])-CALCULATE(SUM(sales[sales_amount]),DATESYTD('Date'[Date]))
• C.CALCULATE(SUM(sales[sales_amount]), SAMEPERIODLASTYEAR ('Date' [Date]))
• D.CALCULATEx(SUM(sales[sales_amount]) DATESYTD ('Date' [Date]))

You plan to create a Power BI report. You have the schema model shown in the exhibit. (Click the exhibit).

The model has the following relationships:
* Store the District based on DistrictID
* Sales to Store based on LocationID
* Sales to Date based on PeriodID
* Sales to Item based on ItemID
You configure row-level security (RLS) so that the district managers of the stores only see the sales from the stores they manage.
When the district managers view the sales report, they see Sales by Items for all stores.
You need to ensure that the district managers can see Sales by items for the stores they manage only.
How should you configure the relationship from Sales to Item?

• A.Change the Cardinality to One to Many (1.*).
• B.Select Assume Referential Integrity.
• C.Change the Cardinality to One to one (1:1).
• D.Change the Cross filter direction to Both.
