Microsoft Advanced Windows Store App Development using C# Sample Questions:

1. DRAG DROP
You are developing a Windows Store app.
You need to use text resources in the app for localization.
You have the following code:

Which code snippets should you include in Target 1, Target 2 and Target 3 to complete the code? (To answer, drag the appropriate code snippets to the correct targets in the answer area. Each code snippet 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.)

2. You need to update the DoWork() method of the background task to meet the requirements.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

A) Confirm that the IsCancellationRequested property of the CancellationToken object is true and exit the task.
B) Update the DoWork() method to receive a Progress object.

D) Update the DoWork() method to receive a CancellationToken object in the arguments of the method.
E) Add the CancellationToken object to the client.GetAsync() method.
F) Get the IsCancellationRequested property from the CancellationToken object and return a TaskCompletionSource object.

3. DRAG DROP
You are developing a Windows Store app that uses a light sensor to detect and respond to light changes. An object named lightSensor is an instance of the sensor service.
The light sensor must detect changes once per second. If the sensor is unable to record as fast as once per second, then it must use the fastest interval possible.
You need to ensure that the app meets the requirements. You have the following code:

Which code snippets should you include in Target 1 and Target 2 to complete the code? (To answer, drag the appropriate code snippets to the correct targets in the answer area. Each code snippet 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.)

4. HOTSPOT
You need to configure the app manifest to support the file download requirements.
Which task type property should you specify? (To answer, select the appropriate property in the answer area.)

5. DRAG DROP
You are developing a Windows Store app.
The app will provide users with the ability to play music remotely on another user's device
and then the other users will guess the name of the song.
You need to access the music storage and to retrieve files and folders.
You have the following code:

Which elements should you include in Target 1, Target 2, Target 3 and Target 4 to complete the code? (To answer, drag the appropriate elements to the correct targets in the answer area. Each element 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.)
