You are developing a Windows Store game. The game allows for interactive online play between users.

The game authenticates users by using the credentials of a third-party site that provides OAuth2 authentication.

You need to implement authentication that uses an implicit grant authorization.

How should you complete the relevant code? (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.)

For implicit grant authorization we use TOKEN response type. Box 2:

Respond with the RequestURL. Note:

  • The implicit grant flow can be used by both web-based and desktop apps. In this flow, the client makes an authorization request to https://login.live.com/oauth20_authorize.srf with request_type=token. This is a standard OAuth 2.0 flow.

    Answer: B,C Explanation: * Example:

    tileNotification.ExpirationTime = DateTimeOffset.UtcNow.AddMinutes(10);

  • This example specifies that the notification should appear in 3 hours. This example uses the DateTime object.

Int16 dueTimeInHours = 3;

DateTime dueTime = DateTime.Now.AddHours(dueTimeInHours);

Question No: 77 – (Topic 5)

You are developing a Windows Store app.

The app will access several web resources that use an OAuth 2.0 authentication provider.

You need to recommend in which class to store user credentials so that users do not have to reenter their credentials when they access the web resources.

Which class should you recommend?

  1. windows.Security.Authentication.Onlineld.OnlineldAuthenticator

  2. Windows.Security.Credentials.UI.CredentialPicker

  3. system.Net.NetworkCredential

  4. windows.Security.Credentials.PasswordVault

Answer: D

Explanation: The task of storing and retrieving user credentials securely and allowing user credentials roam at no cost with the user#39;s Microsoft account is simplified with the Credential Locker.

Storing user credentials in the Credential Locker is a quick, two-step process. 1.Obtain a reference to the Credential Locker using the PasswordVault object from the Windows.Security.Credentials namespace.

2.Create a PasswordCredential object that contains an identifier for your app, the username and the password, and pass that to the PasswordVault.Add method to add the credential to the locker.

Question No: 78 – (Topic 5)

You are developing a Windows Store app.

You need to ensure that the app displays an icon on the lock screen when the app receives a new item.

What should you do?

  1. Declare the background task and enable the control channel property in

    Package.appxmanifest. Call the ToastNotificationManager.CreateToastNotifier() method.

  2. Declare the background task and enable the Push notification property in Package.appxmanifest. Call the BackgroundExecutionManager.RequestAccessAsync() method.

  3. Declare the background task and enable the push notification property in Package.appxmanifest. Call the ToastNotificationManager.CreateToastNotifier() method.

  4. Declare the background task and enable the control channel property in Package.appxmanifest. Call the BackgroundExecutionManager.RequestAccessAsync() method.

Answer: B

Question No: 79 HOTSPOT – (Topic 5)

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:

Note:

  • INotifyPropertyChanged

    The INotifyPropertyChanged interface is used to notify clients, typically binding clients, that a property value has changed.

  • PropertyChangedEventHandler

Example:

// This is a simple customer class that

// implements the IPropertyChange interface.

public class DemoCustomer : INotifyPropertyChanged

{

// These fields hold the values for the public properties. private Guid idValue = Guid.NewGuid();

private string customerNameValue = String.Empty; private string phoneNumberValue = String.Empty;

public event PropertyChangedEventHandler PropertyChanged;

// This method is called by the Set accessor of each property.

// The CallerMemberName attribute that is applied to the optional propertyName

// parameter causes the property name of the caller to be substituted as an argument.
