PL-900 Demonstrate the capabilities of Power Apps Practice Question
A non-profit organization uses Power Apps to manage volunteer information. They have a Dataverse table called 'Volunteers' with columns: Name, Email, Phone, Status (Active/Inactive). They want to create a dashboard that shows the count of active volunteers by city. The city information is stored in a separate 'Address' table related to Volunteers. Which approach should you use to display this data in a canvas app? A) Add a chart control and configure it to aggregate data from the Volunteers table. B) Use a group by in a gallery and apply a filter to count active volunteers by city. C) Create a Power BI tile embedded in the app. D) Use the 'CountRows' function in a label with a filter.
