Q24
DRAG DROP
You are developing a Universal Windows Platform (UWP) app. You have the following XAML markup:
You need to develop the code for Button_Click that displays the date that the user entered by using the selected culture.
You write the following code.
Which code should you insert at line 03? Develop the solution by selecting and arranging the required code blocks in the correct order.
NOTE: You will not need all of the code segments.
Answer:
Q25
You are building a Universal Windows Platform (UWP) app that will be used to view images. When a user clicks an image by using a mouse, the image will increase in size by 20 percent, and then return to its original size when the user releases the mouse. You create event handlers to handle the PointerPressed and PointerReleased events for the image.
The user reports that occasionally, the image fails to return to its original size. You need to ensure that the image returns to its original size. Which three events should you handle? Each correct answer presents part of the solution.
A. PointerExited
B. PointerCaptureLost
C. LostFocus
D. PointerCanceled
E. PointerMoved
F. LostMouseCappture
Answer: BDE
Explanation:
B: PointerCaptureLost might fire instead of PointerReleased. Don’t rely on PointerPressed and PointerReleased events always occurring in pairs. To function properly, your app must listen for and handle all events that represent likely conclusions to the Press action, and that includes PointerCaptureLost.
D: Other events instead of PointerReleased may fire at the end of the action–for example, PointerCanceled or PointerCaptureLost.
E: Mouse input is associated with a single pointer assigned when mouse input is first detected. Clicking a mouse button (left, wheel, or right) creates a secondary association between the pointer and that button through the PointerPressed event. The PointerReleased event is fired only when that same mouse button is released (no other button can be associated with the pointer until this event is complete). Because of this exclusive association, other mouse button clicks are routed through the PointerMoved event.

Q26
DRAG DROP
You are developing a Universal Windows Platform (UWP) app that will be used on desktop computers and phones. The app will use facial recognition. You need to develop a method that verifies whether a camera is present. How should you complete the code? To answer, drag the appropriate code 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.
Answer:
Explanation:
Capture photos and video with MediaCapture.
To get available devices for capturing pictures you can use the following code:
var allVideoDevices = await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture); References:

Q27
DRAG DROP
You are building a Universal Windows Platform (UWP) app. You need to ensure that users can start the app by using voice command in Cortana. Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
These are the basic steps to add voice-command functionality and integrate Cortana with your app using speech or keyboard input:
1. Create a VCD file. This is an XML document that defines all the spoken commands that the user can say to initiate actions or invoke commands when activating your app.
2. Register the command sets in the VCD file when the app is launched.
3. Handle the activation-by-voice-command, navigation within the app, and execution of the command.
Box 1: Create a VCD file. This is an XML document that defines all the spoken commands that the user can say to initiate actions or invoke commands when activating your app.
Box 2: Register the command sets in the VCD file when the app is launched. Here’s an example that shows how to install the commands specified by a VCD file (vcd.xml).
C#
var storageFile =
await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync( new Uri(“ms-appx:///AdventureWorksCommands.xml”)); await
Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager. InstallCommandDefinitionsFromStorageFileAsync(storageFile); Box 3:
Once your app has been launched and the voice command sets installed, specify how your app responds to subsequent voice command activations.
Example:
protected override void OnActivated(IActivatedEventArgs e) { // Was the app activated by a
voice command?
if (e.Kind != Windows.ApplicationModel.Activation.ActivationKind.VoiceCommand) {r
eturn;
}
Etc.

Q28
HOTSPOT
You have the following code:
event1 += new PointerEventHandler(Target_PointerPressed); event2 += new PointerEventHandler(Target_PointerWheelChange); event3 += new PointerEventHandler(Target_PointerReleased); For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Answer:
Explanation:
*PointerPressed occurs when a single finger touches the screen. *PointerWheelChanged occurs when the delta value of a mouse wheel changes. *PointerReleased occurs when that same touch contact is lifted. ThePointerReleased eventoccurs when the pointer device that previously initiated a Press action is released, while within this element. Note that the end of a Press action is not guaranteed to fire a PointerReleased event; other events may fire instead.
Q29
DRAG DROP
You are developing a Universal Windows Platform (UWP) app that will provide users with the ability to assign tasks to their contacts. The app will have a button that users click to display their contact list.
You need to develop the click event handler for the button. How should you complete the code? To answer, drag the appropriate code 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.
Answer:
Explanation:
Example:
private async void PickAContactButton_Click(object sender, RoutedEventArgs e) {
ContactPicker contactPicker = new ContactPicker(); Contact contact = await contactPicker.PickContactAsync(); }

You are developing an app in Microsoft Visual Studio 2015. The source code is stored in a team project in Visual Studio Online. Visual Studio Online is configured to use Team Foundation version control. The team project is configured to use a Builds check-in policy. After you make some changes to the code, the project fails to build because of code errors. You need to provide another developer with the ability to review the code changes. Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
Box 1, Box 2:
From the web portal home page, start a feedback request by clicking the Request feedback button.
Box 3:
Add the feedback reviewers.
Box 4:
Reviewers launch your application and provide feedback through the free Microsoft Feedback Client which they need to install.

Q31
You need to perform exploratory testing of a Universal Windows Platform (UWP) app. What are two possible products that you can use? Each correct answer presents a complete solution.
A. Microsoft Visual Studio
B. Microsoft Visual Studio Online
C. Microsoft Test Manager
D. the Microsoft Platform Ready Test Tool
E. Microsoft Blend for Visual Studio
Answer: BC
Explanation:
B: Exploratory testing using Microsoft’s new Chrome extension, Perfecto’s Microsoft Visual Studio (VSO) extension has the capability to perform manual tests and report bugs directly from within the browser to VSO.
C: Exploratory testing using Microsoft Test Manager While you work with your application, Microsoft Test Manager (MTM) can record your actions, comments, screenshots and other data. The recording makes it easy to reproduce bugs. And you can quickly play back your tests whenever the application is updated.
Incorrect Answers:
D: The Microsoft Platform Ready (MPR) Test Tool is used for platform application readiness and to validate compliance with certification requirements for Windows Server 2012 and Windows Server 2012 R2 applications.
E: Microsoft Blend for Visual Studio is a user interface design tool developed and sold by Microsoft for creating graphical interfaces.
