You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a
Windows Presentation Foundation (WPF) application.
You suspect that the data returned from the database is incorrect.
You need to capture interactions to the database by using IntelliTrace.
Which event type should you capture?

• A. ADO.NET
• B. DataBinding
• C. ServiceModel
• D. Tracing

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
You create a window that contains a Button control and a MenuItem control. Both controls are labeled "Add sugar." The Command properties of the Button and MenuItem controls are set to the same RoutedCommand named AddSugarCommand.
You write the following code segment.
private void CanAddSugar (object sender, CanExecuteRoutedEventArgs e) { ... }
You need to ensure that when the CanAddSugar method sets e.CanExecute to false, the MenuItem and Button controls are disabled.
What should you do?

• A. Create an event handler for the CanExecuteChanged event of the AddSugarCommand command. Call the CanAddSugar method from within the event handler.
• B. Add a CommandBinding object to the CommandBindings property of the window. Set the Command property of CommandBinding to the AddSugarCommand command. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.
• C. Inherit the AddSugarCommand from the RoutedUICommand class instead of the RoutedCommand class. Call the CanAddSugar method from within the constructor of the AddSugarCommand command.
• D. Add a CommandBinding object to the CommandBinding property of the MenuItem control. Set the CanExecute property of the CommandBinding object to the CanAddSugar method.

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application. The application contains the following code fragment.
<StackPanel>
<TextBlock Style="{StaticResource HyStyle)">Hello World</TextBlock>
<Button Style="{StaticResource HyStyle}">Ok</Button>
</StackPonel>
You need to define a style that applies the following properties to the text in the StackPanel object:
- FontSize = 32
- FontWeight = Bold
Which code fragment should you use?

• A. <Style x:Key="MyStyle" TargetType-"(x:Type UserControl)">
  <Setter Property="Control.FontSize" Value="32" />
  <Setter Property="Control.FontWeight" Value="Bold" />
  </Style>
• B. <Style x:Key="MyStyle" TargetType="{x:Type TextElement}">
  <Setter Property="Control.FontSize" Value="32" />
  <Setter Property="Control.FontUeight" Value="Bold" />
  </Style>
• C. <Style x:Key="MyStyle" TargetType="{x:Type Control}">
  <Setter Property="TextElement.FontSize" Value="32" />
  <Setter Property-"TextElement.FontUeight" Value="Bold" />
  </Style>
• D. <Style x:Key="MyStyle" TargetType="{ x : Type Framework-Element} ">
  <Setter Property="TextElement.FontSize" Value="32" />
  <Setter Property="TextElement.FontWeight" Value="Bold" />
  </Style>

You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application.
The application contains a window as shown in the following exhibit.

You need to define a DockPanel control that fits the window.
Which code fragment should you use?

• A. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content="Bottom"
  DockPanel.Dock"Bottom'7><Button Content="Left"/><Button
  Content="Center"/></DockPanel>
• B. <DockPanel>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content-"Left"/><Button
  Content="Center"/>
  <Button Content="Bottom" DockPanel.Dock="Bottom"/></DockPanel>
• C. <DockPanel>
  <Button Content="Left"/>
  <Button Content="Top" DockPanel.Dock="Top"/><Button Content="Bottom"
  DockPanel.Dock="Bottom"/><Button Content="Center"/></DockPanel>
• D. <DockPanel>
  <Button Content-"Left"/>
  <Button Content="Top" DockPanel.Dock="Top"'><Button Content="Center"/>
  <Button Content="Bottom" DockPanel.Dock="Bottom"/></DockPanel>
