2. 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.)

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

3. HOTSPOT
You are developing a Windows Store app.
The app will use certificates issued by a standalone certification authority (CA) for authentication. The standalone CA certificate is stored in a file named Ca.cer. You need to configure the app manifest to ensure that the app can use certificates issued
by the standalone CA.
You have the following XAML markup in the app manifest:

Which code snippets should you insert in Target 1 and Target 2 to complete the XAML markup? (To answer, select the correct code snippet from each drop-down list in the answer area.)
