A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract(Namespace="http://contoso.com")]
public interface IShipping
{ [OperationContract] string DoWork(int id);
}
This is one of several service contracts hosted by your application. All endpoints use SOAP 1.2 bindings
with WS-Addressing 1.0. The System.ServiceModel.MessageLogging trace source in the system.
diagnostics configuration section is configured with one listener.
You need to make sure that only the messages that are returned from the DoWork operation are logged.
Which XML segment should you add to the system.serviceModel/diagnostics/messageLogging/filters
configuration element?

• A.  <add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>
• B.  <add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>
• C.  <add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>
• D.  <add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>

You need to increase the rate by which clients get the required response from the service.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

• A.  Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
• B.  Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.
• C.  Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
• D.  Require the clients to use async operations when calling the service.

Your Windows Communication Foundation (WCF) client application uses HTTP to communicate with the
service. You need to enable message logging and include all security information such as tokens and
nonces in logged messages.
What should you do?

• A.  In the machine configuration file, add the following XML segment to the system.serviceModel configuration section. <machineSettings enableLoggingKnownPii="true" /> In the application configuration file, add the logKnownPii attribute to the message logging diagnostics source and set the value of the attribute to true. In the application configuration file, add the following XML segment to the system.serviceModel configuration section group. <diagnostics>
  <messageLogging logMessagesAtTransportLevel="true"/>
  </diagnostics>
• B.  In the application configuration file, add the following XML segment to the system.serviceModel configuration section group. <diagnostics>
  <messageLogging logMessagesAtTransportLevel="true"
  logEntireMessage="true" />
  </diagnostics>
• C.  In the application configuration file, add the logKnownPii attribute to the message logging diagnostics source and set the value of the attribute to true. Generate the ContosoService class using the Add Service Reference wizard. Add a reference to System.ServiceModel.Routing.dll. Add the following code segment. Dim client As ContosoService = New ContosoService() Dim behavior As SoapProcessingBehavior = New SoapProcessingBehavior() behavior.ProcessMessages = True client.Endpoint.Behaviors.Add(behavior)
• D.  In the machine configuration file, add the following XML segment to the system.serviceModel configuration section. <machineSettings enableLoggingKnownPii="true" /> Generate the ContosoService class using the Add Service Reference wizard. Add the following code segment. Dim client As ContosoService = New ContosoService() client.Endpoint.Behaviors.Add(New CallbackDebugBehavior(True))

You are designing a process for deploying an ASP.NET MVC 2 Web application to IIS 6.0.
You need to ensure that the Web application properly handles Web requests.
Which approach should you recommend?

• A.  Configure IIS to map all requests to aspnet_isapi.dll by using a wildcard script map.
• B.  Modify the Web application to route all requests to an HttpHandler class.
• C.  Modify the Web application to route all requests to an HttpModule class.
• D.  Configure IIS to map all requests to aspnet_wp.exe by using a wildcard script map.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

• A.  Call the Add method on the EntityCollection of the Order entity.
• B.  Use the AddObject method of the ObjectContext to add both Order and Customer entities.
• C.  Set the Value property of the EntityReference of the Order entity.
• D.  Use the Attach method of the ObjectContext to add both Order and Customer entities.
