Question No.24

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have a Power BI model that contains two tables named Sales and Date. Sales contains four columns named TotalCost, DueDate, ShipDate, and OrderDate. Date contains one column named Date.

The tables have the following relationships: The active relationship is on Sales[DueDate].

You need to create measures to count the number of orders by [ShipDate] and the orders by [OrderDate]. You must meet the goal without duplicating data or loading additional data.

Solution: You create a calculated table. You create a measure that uses the new table. Does this meet the goal?

  1. Yes

  2. No

Correct Answer: B

Question No.25

Note: This question is part of a series of questions that use 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 the same in each question in this series.

Start of repeated scenario

You have a Microsoft SQL Server database that contains the following tables.

image

The following columns contain date information:

image

image

image

Date[Month] in the mmyyyy format Date[Date_ID] in the ddmmyyyy format Date[Date_name] in the mm/dd/yyyy format

image

Monthly_returns[Month_ID] in the mmyyyy format The Order table contains more than one million rows.

The Store table has a relationship to the Monthly_returns table on the StoreJD column. This is the only relationship between the tables.

You plan to use Power Bl Desktop to create an analytics solution for the data.

End of repeated scenario.

You are modeling the data in Power Bl.

You need to import only a sample of the data from the Order table.

What are two possible ways to achieve the goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

  1. In the Power Bl model, create a calculated table.

  2. From Query Editor, create a custom column that uses a custom column formula.

  3. From Query Editor, add a select statement that uses a where clause to the source definition.

  4. From Query Editor, create a column by using Column From Examples.

  5. From Query Editor, filter the table by Order_date.

Correct Answer: C

Question No.26

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.
