Scenario: In the Date table, the date_id column has a format of yyyymmdd. Users must be able to see the month in reports
as shown in the following example: Feb 2020.

You need to review the data for which there are concerns before creating the data model.
What should you do in Power Query Editor?
D
Explanation:
Scenario: Data Concerns
You are concerned with the quality and completeness of the sales data. You plan to verify the sales data for negative sales
amounts.
The Column profile feature provides a more in-depth look at the data in a column. It contains a column statistics chart that
displays Count, Error, Empty, Distinct, Unique, Empty String, Min, & Max of the selected column.

You need to provide a solution to provide the sales managers with the required access.
What should you include in the solution?
A
Explanation:
Scenario: The region_id column can be managed by only one sales manager.
You can use Username() or userprincipalname() in DAX with Row-Level Security.
Within Power BI Desktop, username() will return a user in the format of DOMAIN\User and userprincipalname() will return a
user in the format of [email protected].
Incorrect Answers:
B: sales_manager_id is an integer and cannot be converted to a string datatype.

You need to create a relationship between the Weekly_Returns table and the Date table to meet the reporting requirements
of the regional managers.
What should you do?
B
Explanation:
Scenario: Regional managers require a visual to analyze weekly sales and returns.
To relate the two tables we need a common column.
You need to create relationships to meet the reporting requirements of the customer service department.
What should you create?
A
Explanation:
Scenario: The customer service department requires a visual that can be filtered by both sales month and ship month
independently.
In Power BI Desktop, only one relationship can be active between a Fact table and Dimension table, so we need an extra
table.
Use one-to-many relationship to be able to filter.
Incorrect Answers:
C: Cannot make a relation between a date_id and a week_id.
D: The one-to-many relationships between the Sales and the Date tables goes in the other direction: for each date there can
be many sales or shipments.

Which DAX expression should you use to get the ending balances in the balance sheet reports?
B
Explanation:
Scenario: At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the
quarter, as well as for the previous quarter.
Semi-additive calculations, such as balance at end of month, use LASTDATE Functions.

DRAG DROP
You need to create a DAX measure in the data model that only allows users to see projections at the appropriate level of
granularity.
How should you complete the measure? 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.
Select and Place:
Explanation:
Scenario: Revenue projections are set at the monthly level and summed to show projections for the quarter.
Box 1: IF
Box 2: ISFILTERED
ISFILTERED returns TRUE when columnName is being filtered directly. If there is no filter on the column or if the filtering
happens because a different column in the same table or in a related table is being filtered then the function returns FALSE.
Box 3: SUM

Explanation:
Box 1: The Viewer role to the workspace
The Viewer role gives a read-only experience to its users. They can view dashboards, reports, or workbooks in the
workspace, but cant browse the datasets or dataflows. Use the Viewer role wherever you would previously use a classic
workspace set to Members can only view Power BI content.
Box 2: Build
The analysts must be able to build new reports from the dataset that contains the profit and loss data.
Scenario: The reports must be made available to the board from powerbi.com.
The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which
must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that
contains the profit and loss data, but any reports that the analysts build must not be included in the quarterly reports for the
board. The analysts must not be able to share the quarterly reports with anyone.

Deploy and Maintain Deliverables
What is the minimum number of Power BI datasets needed to support the reports?
A
Explanation:
Scenario: Data and Sources
Data for the reports comes from three sources. Detailed revenue, cost, and expense data comes from an Azure SQL
database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is
not related to the profit and loss results, other than they both relate dates.
Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly
projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department,
and product category.
