You are developing a Microsoft .NET 4 application.
You need to ensure that security error trapping handles transparency violations.
What should you do?

• A. Handle only SecurityAction.PermitOnly transparency violations.
• B. Handle only SecurityAction.Assert transparency violations.
• C. Handle only SecurityAction.Demand transparency violations.
• D. Handle all thrown transparency violations explicitly.

You develop a Windows Presentation Foundation (WPF) application. This application is used to output data trends to customer service representatives.
You use threading to keep the UI responsive. You have a function named UpdateUI that updates all of the UI components.
You use the following code to update the _Data variable. (Line numbers included for reference only.)

You need to update the user interface without knowing if you are on the UI thread.
Which code segment should you insert at line 06?

• A. Me.Dispatcher.VerifyAccess()
  Dim [function] = New Action(AddressCf UpdateUI)
  Dim args() As Object = Nothing
  Me .Dispatcher .BeginlnvoJce ([function], args)
• B. If (Me. Dispatcher. CheckAccess())
  Then UpdateUI()
  Else
  Dim (function] = New Action(AddressCf OpdateUI)
  Dim args() As Object = Nothing
  Me .Dispatcher ,BeginInvoIce ( [function; , args)
  End If
• C. If (Me.Dispatcher.CheckAcce33()) Then
  Dim [function] = New Action(Addre33Cf UpdateUI)
  Dim args() As Object = Nothing
  Me.Dispatcher.Beginlnvoke([function], args)
  Else
  UpdateUI()
  End If
• D. Me. Dispatcher.VerifyAccess ()
  UpdateUI()

You use Microsoft .NET Framework 4 to create a Windows application. You use ClickOnce technology to install the application on computers that run Windows 7 with User Access Control (UAC) enabled.
The application requires access to environment variables on each computer.
You need to ensure that users who do not have administrative permissions can install the application.
Which deployment method should you use?

• A. Install from Web.
• B. Start from network share.
• C. Start from Web.
• D. Install from network share.

You are developing a Windows Presentation Foundation (WPF) application. The application contains a converter named DateOutputConverter that formats dates. The window is defined as follows. (Line numbers are included for reference only.)

The window must display the OrderDate value found in shippedOrder. The text box must display the OrderDate formatted by the DateOutputConverter.
You need to ensure that the OrderDate is displayed and formatted correctly.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Insert the following code at line 10.
  <textBox Text="{Binding OrderDate,
  Converter={StaticResource internationalDateConverter}}"
  DataContext.="{StaticResource ResourceKey=shippedOrder}"/>
• B. Insert the following code at line 07.
  <m:DataOutputConverter x:Key"DataOutputConverter"/>
• C. insert the following code at line 10.
  <textBox Text="{Binding OrderDate}"/>
• D. Insert the following code at line 07.
  <m:DateOutputConverter x:Key="internationalDateConverter"/>

You develop a Windows Presentation Foundation (WPF) application. This application is
used to output data trends to customer service representatives.
A data trend analysis is performed in a function named UpdateTrendData. The trend
analysis is a long-running process.
The application contains the following code segment.
Class MainWindow
Private Sub UpdateData(By Val arg As Object) Dim data As Double = UpdateTrendData()
... End Sub
End Class
UpdateData is currently invoked on the UI thread when the form is first displayed.
You need to process the data in a manner that does not cause the UI to freeze.
What should you do?

• A. Use ThreadPool.QueueUserWorkltem to invoke UpdateData.
• B. Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Background.
• C. Use ThreadPool.SetMaxThreads(2,2) and invoke UpdateData.
• D. Use Me.Dispatcher.BeginInvoke to invoke UpdateData passing in the priority of Normal.
