Free Microsoft Power BI Certification (PL-300) Practice Test 15

You have a data model with the Date table related to the Offline Sales table by columns of date data type (Date[Date] -> ‘Offline Sales‘[Due Date]). The Date table is marked as a date table.

Goal: You have to use the appropriate date field to create a quick measure for calculating the Month-over-month change of the Sales Amount.
Solution: You use the Order Date column from the Offline Sales table in the Date field.

Does the solution meet the stated goal?

Select 1 option(s):

Use query parameters instead of hardcoding data source connection details.
You create a Power BI model that combines data from 3 data sources: Azure SQL Server, Analysis Services, and Excel spreadsheet.
You realize that you can browse the Excel file and import data into your model, but Excel doesn‘t support data source parameterization in the default data connector.
How do you parameterize the Excel data source connection? (Select two possible options).

Some users complain that the visual Var Plan by Country/Region is slow to load. You use the performance analyzer to examine the performance of the visual. You observe that the Other tasks require an inordinate amount of time compared to DAX query or Visual display tasks.

From the performance analyzer learnings, how would you fix this issue?

Select 1 option(s):

So, he creates a KPI visual to compare how the revenue in the current quarter compares to the revenue from the previous quarter.
The below representation shows the measures/fields used to build the KPI visual.

But there is something off with the visual. The KPI displays a much higher value (33859) than the goal (Revenue Last Quarter). But you cannot observe this behavior in the trend chart in the background (which is continuously decreasing each quarter).
To debug the issue, you check the underlying data for the visual.

What could be wrong with the visual?
Note:
1. Offline Store Revenue table contains historical (at least four years) revenue data for the company’s offline stores.

Revenue Last Quarter =
IF (ISBLANK([Total Revenue]), BLANK(), CALCULATE ( [Total Revenue], PREVIOUSQUARTER( ‘Date‘[Date] ) ) )
