                                            Question #1

                                            You create a client application by using Microsoft .NET Framework 3.5. The client application consumes a Windows Communication Foundation service that uses the netMsmqBinding binding.
                                            The binding uses a private transactional queue named 28 http://www.abc.com
                                            Library. The following code fragment is part of the application configuration file. (Line numbers are included for reference only.)
                                            01 <endpoint binding="netMsmqBinding" 02 contract="ServiceReference.lLibrary" 03 04 /> You need to specify the address of the endpoint.
                                            Which attribute should you insert at line 03?

                                            • A. address="net.msmq://.\private$\Library"

                                            • C. address="net.msmq://localhost/private/transactional/Library"
                                            • D. address=".\private$\Library"
                                            Answer: B
                                            Question #2

                                            You are creating a Windows Communication Foundation (WCF) client application by using Microsoft .NET Framework 3.5. You write the following binding configuration. (Line numbers are included for reference only.)

                                            You need to ensure that the client application can receive string values that contain a maximum of 5,000 characters.
                                            Which configuration settings should you insert at line 04?

                                            • A. <readerQuotas maxStringContentLength="5000" />
                                            • B. <readerQuotas maxStringContentLength="20000" />
                                            • C. <readerQuotas maxStringContentLength="40000" />
                                            • D. <readerQuotas maxStringContentLength="10000" />

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

                                            Client applications pass an instance of the Customer class to the service.
                                            You create a new version of the data contract and replace the Name property with the FirstName property.
                                            You need to ensure that the existing client applications can continue to consume the service without modifying their code.
                                            Which code segment should you use?

                                            You write the following lines of code.

                                            You need to define the metadata for the DoSomething operation contract so that the parameter element is named Input and the method output element is named Output.
                                            Which code segment should you use to replace the existing operation contract?

                                            • A. Option B
                                            • B. Option D
