                                            You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You set the logKnownPii attribute to true for the only trace source in the app.config file. You discover that the personal identifiable information (PII) is not logged.
                                            You need to ensure that the PII is logged.
                                            What should you do?

                                            • A. Disable encryption of the AppSettings element in the web.config file.

                                            You are creating a distributed application by using Microsoft .NET Framework 3.5.
                                            You use Windows Communication Foundation (WCF) to create the application. The operations provided by the WCF server use the remote resources of other computers.
                                            These methods use the credentials provided by the client applications.
                                            You need to ensure that the WCF server can impersonate the client applications to access the remote resources.
                                            Which client application settings should you use?
