DRAG DROP
-

You plan to create a canvas app with multiple screens.

The app needs to store temporary data while the app is running. The app has the following data requirements:

• Each screen must maintain a separate copy of data and pass the data to another screen.
• The app must be able to update separate rows of a table independently.

You need to configure variables for the data.

Which variable types should you use? To answer, drag the appropriate variable types to the correct requirements. Each variable type 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.

I think the answers are correct: 1. Context variable 2. Collection The first one is NOT "Global variable" because it says "screens MAINTAIN SEPARATE data..." so I guess it should be a context variable passing information with Navigate()

I think 1. Global Variable - because it can be used to access data from anywhere in the app. 2. Collection - It updates seperate rows.

You actually CAN pass a context variable using NAVIGATE eg. Navigate('Screen2';ScreenTransition.Fade;{color:"red"})

The requirement is: Each screen must maintain a separate copy of data and pass the data to another screen. A global variable is available throughout the app and is not a separate copy of data on the screen

1 is wrong. A Context variables cann't pass data to another screen. I think Global variable is the right answer. https://learn.microsoft.com/en-us/power-platform/power-fx/reference/function-updatecontext

Navigate is a function, not variable.

You can set a Context Variable within the Navigate function. This is from the official formula reference: "Context variables are also preserved when a user navigates between screens. You can use Navigate to set one or more context variables for the screen that the formula will display, which is the only way to set a context variable from outside the screen"
