You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
You create an instance of the ServerHost class. You plan to host the WCF service in a Windows service.
You need to link the lifetime of the WCF service to the lifetime of the Windows service.
Which three actions should you perform on the instance of the ServerHost class? (Each correct answer presents part of the solution. Choose three.)

• A. Override the OnStop method.
• B. Subscribe to the Faulted event.
• C. Override the RequestAdditionalTime method.
• D. Override the GetLifetimeService method.
• E. Override the OnStart method.
• F. Override the InitializeLifetimeService method.

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You define the following data contract.

You need to identify the structure of the resulting XML instance document. Which structure will the data contract produce?

• A. Option C
• B. Option A
• C. Option D
• D. Option B

You are creating a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation to create the application. You plan to perform the following tasks:
You write the following code segment.

You need to ensure that only those client applications that provide credentials belonging to the AdminGroup role can access the Remove method. What should you do?

• A. Add the following attribute to the Remove method of the Service class. <PrincipalPermission(SecurityAction.Demand, Role:="AdminGroup")> _
• B. Add the following attribute to the Service class. <PrincipalPermission(SecurityAction.
  Demand, _ Name:="Remove", Role:="AdminGroup")> _
• C. Add the following attribute to the Service class <PrincipalPermission(SecurityAction. Demand,_ Name:="IService. Remove", Role:="AdminGroup")> _
• D. Add the following attribute to the Remove method of the IService interface. <PrincipalPermission(SecurityAction.Demand, Role:="AdminGroup")> _

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service that will be consumed by an ASP. NET application. The WCF application and the ASP.NET application will be deployed on the same server. You need to ensure that the WCF service meets the following requirements:
The communication between the applications incurs minimum latency. The binding satisfies the ordered delivery constraint that is specified in the service implementation by using the DeliveryRequirements attribute.
Which binding object should you use?

• A. NetNamedPipeBinding
• B. NetTcpBinding
• C. NetPeerTcpBinding
• D. WSHttpBinding

You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5.
You need to inspect the parameters on the client application.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

• A. Implement the IParameterlnspector interface.
• B. Implement the ICIientMessagelnspector interface.
• C. Insert a behavior before you call the ClientBase.Open method.
• D. Implement the lEndpointBehavior behavior to add the parameter inspector to the Dispatcher. ClientOperation.Parameterlnspectors method.
• E. Implement the lEndpointBehavior behavior to add the parameter inspector to the Dispatcher. DispatchOperation.Parameterlnspectors method.
• F. Insert a code segment that creates a behavior in the ICallContextlnitializer.BeforelnvokeO method.
