You are developing a Windows Presentation Foundation (WPF) application. A TextBlock control has DataContext bound to a static resource named Book. The ToolTip attribute of TextBlock displays the full book titles.
You create a converter named TrimTitleConverter to shorten the book titles to three words in the Text attribute of the TextBox. You add the converter to the Resources section of the MainWindow.xaml file as follows. (Line numbers are included for reference only.)

You need to ensure that the shortened book titles appear only in the Text attribute of TextBlock.
Which markup segment should you use to replace lines 06 through 09?

• A. <TextBlock
  ToolTip="{Binding Title,
  Converter={StaticResource ResourceKeyTrimConverter}}"
  Text=Binding RelativeSource-
  {ReiativeSaurce Self), Path-ToolTip}" DataContext-"{StaticResource ResourceKey-Book) "/>
• B. <TextBlock
  ToolTip-"{Binding Title}"
  Text={Binding RelativeSource=
  {RelativeSource Self}, Path=ToolTip,
  Converter={StaticResource ResourceKey=TrimConverter}}" DataContext="{StaticResource
  ResourceKey=Book"/>
• C. <TextBlock
  ToolTip="{Binding Title,
  Converter-{StatlcResource ResourceKey=TrimConverter)}"
  Text-"(Binding RelativeSource-
  {RelativeSource TeaplatedParent}, Path-ToolTip}" DataContext = "{StaticResource
  ResourceKey=Book} "/>
• D. <TextB1ock
  ToolTip="{Binding Title)" Text="{Binding RelativeSource=
  {RelativeSource TemplatedParent}, Path=ToolTip,
  Converter{StaticResource ResourceKey=TrimConverter}}" DataContext="{StaticResource
  ResourceKey=Book)"/>

You are developing a Windows Presentation Foundation (WPF) application with multiple windows.
The majority of the buttons within the application are styled consistently. However, three buttons within the application must be styled differently.
You need to ensure that the application can handle this styling requirement.
What should you do?

• A. Create the styles in the application resources. Specify the TargetType property to be Button for the default style but not for the three buttons.
• B. Create the styles in the application resources. Omit the Key property for the default Button style and specify the Key property for the Button style and the three buttons.
• C. Create the styles in the main window resources. Omit the Key property for the default Button style and specify the Key property for the Button style and the three buttons.
• D. Create the styles in the main window resources. Specify the TargetType property to be Button for the default style but not for the three buttons.

You are developing a Windows Presentation Foundation (WPF) application that contains a custom Button control.
The custom Button control can be set as active by setting an IsActive property to true. You need to ensure that the IsActive property can be bound to a business object.
What should you do on the custom Button control?

• A. Implement INotifyPropertyChanged
• B. Implement IsActive as a Microsoft .NET property.
• C. Implement IsActive as a Dependency property.
• D. Implement IQueryable.
