                                            You need to programmatically add the following endpoint definition to the service. http://localhost:8000/ExamService/service
                                            Which code segment should you use?

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


                                            3. You are creating a client application by using Microsoft .NET Framework 3.5.

                                            B) Insert the following code segment at line 05.
                                            client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
                                            Insert the following code segment at line 09.
                                            count=(result.AsyncState as DocumentServiceClient). EndDeleteDocument(nul)
                                            C) Insert the following code segment at line 05.

                                            count=client.EndDeleteDocument(result);
                                            Insert the following code segment at 09.
                                            result.AsyncWaitHandle.WaitOne();
                                            D) Insert the following code segment at line 05.
                                            client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
                                            Insert the following code segment at line 09.
                                            result.AsyncWaitHandle.WaitOne(); int count=(result as DocumentServiceClient).
                                            EndDeleteDocument(result);


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

                                            You have not deployed the IMathService service.

                                            a lot of the same questions but there are some differences. Still valid. Tested out today in U.S. and was extremely prepared, did not even come close to failing.
