                                            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. You create the following service contract.

                                            You need to create an endpoint for the service contract in the application configuration file.
                                            Which endpoint should you use?

                                            A) <endpointaddress="" binding="basicHttpBinding" _ contract="MyServices.ServiceConfig"/>
                                            B) <endpointaddress="" binding="basicHttpBinding" _ contract="MyServices.MyService"/>
                                            C) <endpointaddress="" binding="basicHttpBinding" _ contract="HyService"/>
                                            D) <endpointaddress="" binding="basicHttpBinding" _ contract="ServiceConfig"/>


                                            2. You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. You configure the Windows Communication Foundation (WCF) service to be exposed by using the HTTP and TCP endpoints. You plan to deploy the WCF service.
                                            You need to identify the host environment that provides the following services:
                                            Which hosting environment should you use?

                                            A) Microsoft Internet Information Services 6.0
                                            B) Microsoft Windows Service
                                            C) Microsoft COM+ 1.5
                                            D) Microsoft Windows Process Activation Service


                                            3. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The metadata for the service is available at http://localhost:8080/MyService/mex.
                                            The svcutil.exe tool generates the following two files from the metadata:
                                            You need to ensure that the configuration file is merged with an existing app.config file.
                                            Which command should you use?

                                            A) Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config
                                            B) Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /mergeConfig
                                            C) Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config /mergeconfig
                                            D) Svcutil http: //localhost:8080/MyService/mex /out:Proxy.cs /config:app.config /noconfig


                                            4. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be exposed for consumption. You need to ensure that the service supports interoperability with the broadest possible number of Web Service toolkits. The service must also support transport-level security. Which configuration setting should you use?

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


                                            5. You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.)
                                            01 public interface IMyService
                                            02{
                                            04 string ProcessString(string name);
                                            05}
                                            You create a host for the WCF service. You also create a service endpoint at http://localhost:8080/service. You add an instance of the HttpTransferEndPointBehavior class to the host.
                                            You need to ensure that the ProcessString method can be invoked from a Web browser by using the URL http://localhost:8080/service/process? name=value.
                                            Which code segment should you insert at line 03?
