You need to design the data model to meet the report requirements.
What should you do in Power BI Desktop?


A.

From Power Query, use a DAX expression to add columns to the Orders table to calculate the calendar quarter of the OrderDate column, the calendar month of the OrderDate column, the calendar quarter of the ShippedDate column, and the calendar
month of the ShippedDate column.


B.

From Power Query, add columns to the Orders table to calculate the calendar quarter and the calendar month of the OrderDate column.

column in the Orders table and an inactive relationship to the ShippedDate column in the
Orders table.





B.
  

From Power Query, add columns to the Orders table to calculate the calendar quarter and the calendar month of the OrderDate column.



Explanation:
Use Power Query to calculate calendar quarter and calendar month.
Scenario:
A single dataset must support all three reports:
- The Top Customers report will show the top 20 customers based on the highest sales
amounts in a selected order month or quarter, product category, and sales region.
- The Top Products report will show the top 20 products based on the highest sales
amounts sold in a selected order month or quarter, sales region, and product category.
The data model must minimize the size of the dataset as much as possible, while
meeting the report requirements and the technical requirements.

You have a report that includes a card visualization.
You need to apply the following conditional formatting to the card while minimizing design
effort.
For values that are greater than or equal to 100, the font of the data label must be dark red.
For values that are less than 100, the font of the data label must be dark gray.
Which type of format should you use?


A.

Color scale

You use an R visual to produce a map of 500,000 customers. You include the values of
CustomerID, Latitude, and Longitude in the fields sent to the visual. Each customer ID is
unique.
In powerbi.com, when users load the visual, they only see some of the customers.
What is the cause of the issue?


A.

The visual was built by using a different version of R.


B.

The data comes from a Microsoft SQL Server source.


C.

The data is deduplicated.


D.

Too many records were sent to the visual.





D.
  

Too many records were sent to the visual.



Explanation:
R visuals in the Power BI service have a few limitations including:
Data size limitations – data used by the R visual for plotting is limited to 150,000
rows. If more than 150,000 rows are selected, only the top 150,000 rows are used
and a message is displayed on the image. Additionally, the input data has a limit of
250 MB.

You have sales data in a star schema that contains four tables named Sales, Customer,
Date, and Product.
The Sales table contains purchase and ship dates.
Most often, you will use the purchase date to analyze the data, but you will analyze the
data by both dates independently and together.
You need to design an imported dataset to support the analysis. The solution must
minimize the model size and the number of queries against the data source.
Which data modeling design should you use?


A.

Use the Auto Date/Time functionality in Microsoft Power BI and do NOT import the Date table.


B.

Duplicate the Date query in Power Query and use active relationships between both Date tables.


C.

On the Date table, use a reference query in Power Query and create active relationships between Sales and both Date tables in the modeling view.


D.

Create an active relationship between Sales and Date for the purchase date and an
inactive relationship for the ship date





D.
  

Create an active relationship between Sales and Date for the purchase date and an
inactive relationship for the ship date



Explanation:
Only one relationship can be active.
Note: If you query two or more tables at the same time, when the data is loaded, Power BI
Desktop attempts to find and create relationships for you. The relationship options
Cardinality, Cross filter direction, and Make this relationship active are automatically set.

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.
