You are developing a Windows Store reporting app for corporate use. The app authenticates users by using Active Directory Domain Services (AD DS) credentials.
You need to ensure that users have the option of saving their credentials when they log in to the app.
You have the following code: Which code snippets should you insert in Target 1, Target 2, and Target 3 to complete the code? (To answer, drag the appropriate code snippets to the correct target 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 identify alternative methods of displaying information from the FeedRetriever class.
Which data controls can you use to achieve this goal? (Each correct answer presents a complete solution. Choose all that apply.)

The app has the following accessibility requirements: - The automation name of each text box must be the same as the text box caption. - Each Label element must be associated with its corresponding text box. You need to create an interface that 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 appropriatecode snippets to the correct targets in the answer area. Each code snippet may be used once, more than once, or not at all. You mayneed to drag the split bar between panes or scroll to view content.)

You are developing a Windows Store app Chat provides users with the ability to select a video file from the file system. Once the file is selected, the video begins to play.
this.media is declared as a MediaElement in VideoPage.xaml and _position is declared as a private TimeSpan member that stores the point at which the video stopped when the app was terminated.
You need to ensure that if the app is terminated, the next time the app starts, the app resumes playing the video at the point the video was stopped.
You have the following code: (Line numbers are included for reference only.)

Which code segments should you insert at lines 04, 13, and 17? (To answer, drag the
appropriate code segments to the correct locations in the answer area. Each code segment 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.)

5. HOTSPOT
A class named AccountViewModel includes a property named Name that will be bound to a control.
The Name property will occasionally be updated programmatically. The updated values must be reflected in the bound control.
You need to implement the interface so that the AccountViewModel class can inform WinRT when there is a new value to display.
You have the following code:

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