A canvas app has a button that triggers a Power Automate flow to process a large file. The flow can take up to 5 minutes. The app must not block the user during this time, and the user should be notified when the flow completes. Which approach should you use?

Use the Run() function and wrap it in a Concurrent() call with other app logic.

Use the Run() function and set a timer to check a status variable that the flow updates.

Use a flow that returns immediately with a job ID, and have the app poll a status endpoint using a timer control.

Use the Run() function and show a notification when the flow returns.

A canvas app has a collection of employee records with columns: Name, Department, and Salary. Users need to see a list of departments with the total salary paid to employees in each department. Which Power Fx expression should you use to populate a gallery?

AddColumns(GroupBy(Employees, "Department", "DepartmentEmployees"), "TotalSalary", Sum(DepartmentEmployees, Salary))

Summarize(Employees, Department, TotalSalary = Sum(Salary))

Distinct(Employees, Department) & Sum(Employees, Salary)

GroupBy(Employees, "Department", "DepartmentEmployees")

What is the primary purpose of a reusable component library in Power Apps?

To store version history of canvas apps

To store data sources used by canvas apps

To package canvas apps for deployment to production

To share and reuse components across multiple canvas apps

A company has multiple canvas apps that each display a common header with a logo, navigation buttons, and a user profile picture. The header must look and behave identically across all apps, and updates should be made once and automatically propagate. Which approach should you take?

Use a Power Automate flow to push header updates to each app's controls.

Create a component in a component library and import it into each canvas app.

Create a separate canvas app that contains the header and embed it as an iFrame in each app.

Copy the header controls from one app and paste them into each of the other apps.
