Answer: A QUESTION 88You are developing a Windows Store app.The app will use a model that is defined by using the following code:You need to create a class to represent a collection of Customer objects.The class will be used for data binding.The solution must ensure that if changes are made to the objects of the class, a notification will be sent to the user interface (UI) controls to which the collection is bound.You have the following signature:public classCustomerList : Target 1<Target 2>Which elements should you include in Target 1 and Target 2 to complete the signature for the collection class? (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.)Answer:Explanation:- In C# and Visual Basic, the generic ObservableCollection<T> class is a good collection choice for data binding, because it implements the INotifyPropertyChanged and INotifyCollectionChanged interfaces. QUESTION 89A 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.)Answer:Explanation:- INotifyPropertyChangedThe INotifyPropertyChanged interface is used to notify clients, typically binding clients, that a property value has changed.- PropertyChangedEventHandlerExample:// 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. QUESTION 90You are developing a Windows Store app.The app includes the following event procedure:Void OnSettingsPaneOpened(SettingsPanesettingsPane,SettingsPaneCommandsRequestedEventArgseventArga)You need to call the event procedure when the user opens the settings pane.Which three code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)Answer:Explanation:Box 1: SettingsPanesp = null;Box 2: sp = SettingsPane.GetForCurrentView();Box 3: sp.CommandsRequested += OnSettingsPaneOpened;Note:- The SettingsPane class is a static class that enables the app to control the Settings Charm pane. The app can add or remove commands, receive a notification when the user opens the pane, or open the pane programmatically.- The show method displays the Settings Charm pane to the user.- The GetForCurrentView method gets a SettingsPane object that is associated with the current app view (that is, with CoreWindow). QUESTION 91You 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.)Answer: QUESTION 92Hotspot QuestionYou develop a Windows Store app.The Capabilities section of the app manifest is configured as shown in the exhibit. (Click the Exhibit button.)To answer, complete each statement according to the information presented in the exhibit. Each correct selection is worth one point.Answer: QUESTION 93You are developing a Windows Store app.You need to implement claims according to their appropriate use.Which claim is appropriate for each purpose? (To answer, drag the appropriate claims to the correct locations in the answer area. Each claim 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:Box 1: GroupBox 2: CustomBox 3: IdentityNote:Active Directory Federation Services (ADFS) upports three types of claims:- Identity claim. There are three types of identity claims:User Principal Name (UPN). Indicates a Kerberos-style user UPN, such as user@realm.E-mail. Indicates RFC 2822style e-mail names of the form user@domain.Common name.Indicates an arbitrary string that is used for personalization.Examples include John Smith or Tailspin Toys Employee.Note that you cannot guarantee the uniqueness of the common name claim.Therefore, use caution when you are using this claim type for authorization decisions.- Group claim. Indicates a user's membership in a group or role.- Custom claim. Contains custom information about a user, such as an employee ID number.Reference: Claims-Aware Applications QUESTION 94You 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.)Answer:Explanation:Note:- AuthenticationProtocol.DigestThe authentication protocol is digest. Credentials are returned to the caller as plaintext.- CredentialSaveOption.hiddenThe "Save credentials?" dialog box is not displayed at all.- CredentialPicker.PickAsyncDisplays a dialog box to the user and collects credentials from the user.Incorrect:- CredentialSaveOption.unselectedThe "Save credentials?" dialog box is not selected, indicating that the user doesn't want their credentials saved. QUESTION 95You have been given software that performs bit-rate manipulation of audio streams recorded using a microphone.The software is complex and is written in C++.Your organization does not have the budget to have the software rewritten for a Windows Store app.What are your recommendations for the conceptual design of a Windows Store app that does bit-rate manipulation? (Choose all that apply.) A.    Develop a WinMD component in C++ incorporating the existing software.B.    Develop a Windows Store app and use the C++/WinMD component for bit-rate manipulation.C.    Such an application is impossible to build unless the C++ component is rewritten in C#.D.    Use WinRT APIs (application programming interfaces) to implement the bit-rate manipulation algorithm.E.    Use the existing test procedures for the C++ component to test the C++/WinMD component. Answer: ABE QUESTION 96You are developing a dependency property named TotalAmount for a Windows Store app.The TotalAmount property must default to zero.The class that contains the TotalAmount property must provide a class property that gets and sets the value of the dependency property.You need to create the dependency property and the class property.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 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.)Answer:Explanation:Note:- DependencyProperty PropertyMetadataDependency property metadata exists as an object that can be queried to examine the characteristics of a dependency property. This metadata is also accessed frequently by the property system as it processes any given dependency property QUESTION 97You are designing your Windows Store app with the MVVM design pattern.In the data access layer, you use an XML file to store and retrieve data.To maximize reuse of code across Windows Store, WPF, and Silverlight applications, how should you implement data access layer in your application?
