HOTSPOT
You are developing a Windows Store app that allows users to copy music from their local computers to removable storage.
The app displays songs grouped by the month the song was downloaded and allows individual songs to be copied to the removable storage device. The user interface for selecting and copying songs uses data binding.
You need to load and return songs in a format appropriate for data binding.
How should you complete the code segment? (To answer, select the appropriate line of code from each drop-down list in the answer area.)

Correct Answer:

You are developing a Windows Store app that uploads large video files to a web-based video sharing service. You have the following requirements:
- When the app runs on a metered network connection, upload operations must be suspended.
- When the app is suspended, upload operations must continue.
You need to ensure that the app meets the requirements.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

• A.Create a BackgroundTransfer object and call the UploadAsync() method.
• B.Use the XHR class to initiate and run a web upload.
• C.Enable the Internet (Server) capability in the package.appxmanifest file.
• D.Create an HttpClient object and use the PutAsync() method to perform the transfer asynchronously.
• E.Enable the Internet (Client) capability in the package.appxmanifest file.
• F.Create a BackgroundUploader object and call the CreateUploadAsync() method.

• A.the Networklnfomation.GetlnternetConnectionProfileQ method in the OnLaunched event handler
• B.the GeoLocator.PositionChanged event handler
• C.the GeoLocator.GetGeopositionAsync() method in the OnLaunched event handler
• D.the GeofenceMonitor.GeofenceStateChanged event handler
