Microsoft Essentials of Developing Windows Store Apps using C# Sample Questions:

Question 1

You need to choose the appropriate data binding strategy for the image list box.
Which method should you use?

A. System.Drawing.ImageConverter.ConvertTo(value, typeof(Image))
B. System.Drawing.ImageConverter.ConvertFrom(value, typeof(Image), CultureInfo.CurrentUICulture)
C. IValueConverter.Convert()
D. IValueConverter.ConvertBack ()

Question 2

You need to implement the required image magnification and manipulation requirements for selected images.
Which actions should you perform? (Each correct answer presents part of the solution. Choose all that apply.)

A. Add a ManipulationDelta event to the SelectedImage object.
B. Use the ManipulationDeltaRoutedEventArgs.Delta.Scale value to implement optical zoom.
C. Add a ManipulationComplete event to the SelectedImage object.
D. Add a ManipulationMode attribute to the Selectedlmage object and set the attribute to Translate.
E. Add a ManipulationMode attribute to the SelectedImage object and set the attribute to All.
F. Use the ManipulationDeltaRoutedEventArgs.Delta.Expansion value to implement optical zoom.

Question 3

DRAG DROP
You are developing a Windows Store app.
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.)

Question 4

You are developing a Windows Store app that will read data from a file that is stored on a hard disk. The app will display that data on the screen.
You need to ensure that portions of the app can be reused in WinRT, Windows Presentation Foundation (WPF), Microsoft Silverlight, and Windows Phone apps.
What should you do?

A. Create a page and a ViewModel object. Set the page's DataContext property to reference the ViewModel object. Program the ViewModel object to load data from the file and populate its properties with that data. Program the page to consume the data by using data binding.
B. Create a page, a ViewModel object, and a FileHelper class. Set the page's DataContext property to reference the ViewModel object. Program the ViewModel object to use the FileHelper class to load data from the file, and populate its properties with that data. Program the page to consume the data by using data binding.
C. Create a page and a ViewModel object. Set the page's DataContext property to reference the ViewModel object. Program the page so that its Loaded event reads data from the file and populates the properties of the ViewModel object with that data. Program the page to consume the data by using data binding.
D. Create a page and a ViewModel object. Program the page to use the Loaded event to load data from the file and then update the page contents to reflect the data from the file. Program the ViewModel object to use the Windows.Data.FileLoader class to populate its properties from the file.

Question 5

DRAG DROP
You are developing an app named App1 that will read text aloud.
You need to ensure that when users use App1, they can change the voice of the reader.
You have the following code:

Which elements should you include in Target 1 and Target 2 to complete the method? (To answer, drag the appropriate elements to the correct targets. 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.)
