                                            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.

                                            • A. wsFederationHttpBinding
                                            • B. webHttpBinding

                                            You are creating a remote database management application by using Microsoft Windows Forms and Microsoft .NET Framework 3.5
                                            You use the Windows Communication Foundation model to create the application. You write the following code segment. (Line numbers are included for reference only.)

                                            You need to ensure that each time a client application calls the Open() method, a new service instance is created.
                                            Which code segment should you insert at line 03?

                                            You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service accepts service requests from different partner applications. One of the partner applications occasionally receives faults. You need to identify why the service is generating faults. You must accomplish this goal without interrupting the service. What should you do?

                                            • A. Configure the Service Tracing options in the application configuration file. Analyze the
                                              trace results by using the SvcTraceViewer.exe program.
                                            • B. Add the following code segment to the application configuration file.
                                              <system.diagnostics>
                                              <switches>

                                              </ switches>
                                              </system.diagnostics>
                                            • C. Run SvcTraceViewer.exe /register on the WCF server.
                                            • D. Connect remotely to the WCF service by using a debugger. Place breakpoints in the
                                              exception handling code segment.
