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

                                            1. You create a Windows Communication Foundation (WCF) service by using Microsoft .NET framework 3.5. You write the following code segment for a service contract.

                                            You need to ensure that the WCF service meets the following requirements:
                                            Which method implementation should you use?

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

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

                                            The service uses a transactional binding. The TransactionFlow property for the binding is set to True. You need to ensure that the MyMethod method meets the following requirements: Which code segment should you insert at line 04?

                                            A) <OperationBehavior(TransactionScopeRequired:=True)> _ <TransactionFlow(TransactionFlowOption.Allowed)> _
                                            B) <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.Mandatory)> _
                                            C) <OperationBehavior(TransactionScopeRequired:=True)> _<TransactionFlow(TransactionFlowOption.Mandatory)> _
                                            D) <OperationBehavior(TransactionScopeRequired:=False)> _ <TransactionFlow(TransactionFlowOption.Allowed)> _


                                            3. You are creating a Windows Communication Foundation (WCF) client application by using Microsoft .NET Framework 3.5.
                                            The WCF service transfers data to the client applications by using the streaming transfer
                                            mode.
                                            You need to create an endpoint that supports the streaming transfer mode.
                                            Which binding should you use?

                                            A) basicHttpBinding
                                            B) webHttpBinding
                                            C) wsFederationHttpBinding
                                            D) wsHttpBinding


                                            4. 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 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.
                                            You need to host the service in a medium trust environment on a Web server.
                                            Which two bindings should you use? (Each correct answer presents a complete solution. Choose two.)

                                            A) NetMsmqBinding
                                            B) WebHttpBinding
                                            C) BasicHttpBinding
                                            D) NetTcpBinding
