You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following code segment.

Client applications pass an instance of the Customer class to the service.
You create a new version of the data contract and replace the Name property with the FirstName property. You need to ensure that the existing client applications can continue to consume the
service without modifying their code. Which code segment should you use?

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

You are creating a distributed application by using Microsoft .NET Framework 3.5.
The application uses Windows Communication Foundation (WCF). The distributed application provides point-to-point security.
You need to ensure that the distributed application provides end-to-end security instead of point-to-point security.
Which binding mode should you use?

• A.wsHttpBinding with Transport security
• B.wsHttpBinding with Message security
• C.netNamedPipeBinding with Transport security
• D.netTcpBinding with Transport security

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You create a class named Customer for the WCF service. The Customer class has properties named Id, Name, and BalanceDue.
You plan to convert the Customer class into a data contract.
You need to ensure that only the Id property and the Name property are passed to the client applications.
Which code segment should you use?

• A.<DataContract()> _ Public Class Customer <DataMember(EmitDefaultValue:=True)> _ Public Property Id() As Integer ... End Property <DataMember(EmitDefaultValue:=True)> _ Public Property Name() As String ... End Property <DataMember()> _ Friend Property BalanceDue() As Double ... End Property End Class
• B.<DataContract()> _
  Public Class Customer
  <DataMember()> _
  Private Property Id() As Integer
  ...
  End Property
  <DataMember()> _
  Public Property Name() As String ... End Property Public Property BalanceDue() As Double ... End Property End Class
• C.<DataContract()> _
  Public Class Customer
  Public Property Id() As Integer
  ...
  End Property
  Public Property Name() As String
  ...
  End Property
  Private Property BalanceDue() As Double
  ...
  End Property
  End Class
• D.<DataContract()> _ Public Class Customer <DataMember()> _ Public Property Id() As Integer ... End Property <DataMember()> _ Public Property Name() As String ... End Property <DataMember(EmitDefaultValue:=False)> _ Public Property BalanceDue() As Double ... End Property End Class

You are creating a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5.
The service will be hosted on a Web server. You add the following code fragment to the
.svc file.
<% @ServiceHost factory="ExamServicefactory" Service="ExamService" %>
You need to create the instances of the services by using the custom ExamServicefactory class.
Which code segment should you use?

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

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) Web service. The Web service is consumed by third-party applications. You need to ensure that the WCF service provides interoperable and secure end-to-end communications. What should you do?

• A.Use the wsHttpBinding binding along with the message-level security.
• B.Use the netTcpBinding binding along with the message-level security.
• C.Use the basicHttpBinding binding along with the transport-level security.
• D.Use the netNamedPipeBinding binding along with the message-level and the transport-level securities.
