                                            Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

                                            1. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be hosted in a managed Console application.
                                            The service endpoint has an address that is relative to the base address of the service.
                                            You need to programmatically add the base address to the service.
                                            What should you do?

                                            A) Create and add a custom endpoint behavior to the service.
                                            B) Create and add a custom operation behavior to the service.
                                            C) Call an AddServiceEndpoint method of the ServiceHost class.
                                            D) Call a constructor of the ServiceHost class.


                                            2. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
                                            You need to ensure that the callback channel between the service and the client application is available for the service to send a status message.
                                            Which code segment should you use?

                                            A) if(((ICommunicationObject)callback).State== CommunicationState.Created)
                                            B) if(((ICommunicationObject)callback).State== CommunicationState.Opening)
                                            C) if(((ICommunicationObject)callback).State== CommunicationState.Faulted)
                                            D) if(((ICommunicationObject)callback).State== CommunicationState.Opened)


                                            3. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You want to use a built-in binding to support reliable sessions.
                                            You need to create a service that uses SOAP to transfer messages between endpoints. The service must deliver the messages only once, and in the same order in which they were sent.
                                            Which type of binding should you use?

                                            A) BasicHttpBinding
                                            B) NetPeerTcpBinding
                                            C) WSDualHttpBinding
                                            D) NetMsmqBinding


                                            4. You have created a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
                                            The existing service interface is named IMyService, and contains the following code segment.

                                            You create a new service named IMyServiceVI that contains an operation named DoSomethingElse.
                                            You need to ensure that existing client applications are still able to access the IMyService. DoSomething method without modifying client code. Which code segment should you use?

                                            A) Option A
                                            B) Option C
                                            C) Option D
                                            D) Option B


                                            5. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following binding configuration in the configuration file. (Line numbers are included for reference only.)
                                            01 <wsHttpBinding>
                                            02 <binding name="ssl">
                                            04 </binding> 05 </wsHttpBinding>
                                            You need to ensure that the following requirements are met:
                                            Which configuration setting should you insert at line 03?

                                            A) Option A
                                            B) Option C
