You need to ensure that the app performs the download operation asynchronously in a background
task.
Which three actions should you perform in sequence? (To answer, move the appropriate actions
from the list of actions to the answer area and arrange them in the correct order,)

HOTSPOT
You are developing a Windows Store app that displays and prints information. You have the

You are developing a Windows Store app that prints documents.
You need to ensure that the app enables the user to specify the paper size.
Which four actions should you perform in sequence? (To answer, move the appropriate actions from

You are developing a Windows Store app that prints documents. An object named printManager
manages the print flow. An object named printDocument sends output to the printer.
You need to ensure that the app allows the user to preview the print layout of the entire document.
Which event should you handle to construct the print preview of the entire document?

DRAG DROP
You are developing your first Windows Store app and submitting it to the Windows Store.
The app uses a cloud server to send notifications by using Windows Push Notification Service (WNS).
You need to authenticate the cloud server with WNS.
Which five actions should you perform in sequence? (To answer, move the appropriate actions from
the list of actions to the answer area and arrange them in the correct order.)

DRAG DROP
You are developing a Windows Store app that uses the Windows Push Notification Service (WNS) to
provide real-time updates to users. The app uses an HTTP request to authenticate a cloud service to
interact with WNS.
The Package Security Identifier (SID) prefix is app://.
Parameter values must be URL encoded.
You need to ensure that the authentication request provides the required parameters.
Which parameters should you use? (To answer, drag the appropriate parameters to the correct
location or locations. Each parameter 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.)
