You review a Power BI report in Reading view mode.
What filter type can you add to the report?

Answer options:

A.Report
B.None
C.Drillthrought
D.Page
E.Dashboard
F.Visual

Correct Answer: B 
You can interact with Power BI reports in two view modes: Editing and Reading. 
Power BI provides the four types of filters to use in the reports: Report — this type applies to all the pages in the report.
Page — this type applies to all tiles on the current report page.
Visual — this type applies only to a single tile.
Drillthrough — this type allows additional details on a specific tile.
In Editing mode, you can add any of the four filter types. When you save a report, filters are also saved with the report. 
In Reading mode, users can interact with a report and use the filters saved with a report in Editing mode but cannot add or remove them. 
All other options are incorrect.
