Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

1. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You need to programmatically add the following endpoint 49 http://www.abc.com definition to the service.
http://localhost:8000/ExamService/service Which code segment should you use?

A) Dim baseAddress As String = "http: //localhost:8000/ExamService"Dim bindingl As New BasicHttpBindingQUsing host As New ServiceHost(GetType (ExamService)) host.AddServiceEndpoint(GetType(IExam), bindingl, baseAddress)End Using
B) Dim baseAddress As String = _ "http: //localhost:8000/ExamService/service"Dim bindingl As New BasicHttpBindingQUsing host As New ServiceHost(GetType(ExamService)) host.AddServiceEndpoint(GetType(IExam), bindingl, baseAddress)End Using
C) Dim baseAddress As String = _"http: //localhost:8000/ExamService/service"Dim bindingl
As New NetTcpBindingQUsing host As New ServiceHost(GetType(ExamService))
host.AddServiceEndpoint(GetType(IExam),
bindingl, baseAddress)End Using
D) Dim baseAddress As String = "http: //localhost:8000/ExamService"Dim bindingl As New WSHttpBindingQUsing host As New ServiceHost(GetType (ExamService)) host.AddServiceEndpoint(GetType(IExam), bindingl, baseAddress)End Using

2. You are creating a distributed application by using Microsoft .NET Framework 3.5.
The application uses Windows Communication Foundation (WCF). The distributed application provides point-to-point security.
You need to ensure that the distributed application provides end-to-end security instead of point-to-point security.
Which binding mode should you use?

A) wsHttpBinding with Transport security
B) wsHttpBinding with Message security
C) netTcpBinding with Transport security
D) netNamedPipeBinding with Transport security

3. You are creating a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation to create the application. You plan to perform the following tasks:
You write the following code segment.

You need to ensure that only those client applications that provide credentials belonging to the AdminGroup role can access the Remove method. What should you do?

A) Add the following attribute to the Remove method of the Service class. [PrincipalPermission(SecurityAction. Demand, Role="AdminGroup")]
B) Add the following attribute to the Service class. [PrincipalPermission(SecurityAction. Demand, Name="IService. Remove", Role="AdminGroup")]
C) Add the following attribute to the Remove method of the IService interface. [PrincipalPermission(SecurityAction. Demand, Role="AdminGroup")]
D) Add the following attribute to the Service class. [PrincipalPermission(SecurityAction.Demand, Name="Remove", Role="AdminGroup")]

4. You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5.
You need to inspect the parameters on the client application.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

A) Implement the lEndpointBehavior behavior to add the parameter inspector to the Dispatcher. ClientOperation.Parameterlnspectors method.
B) Insert a behavior before you call the ClientBase.Open method.
C) Implement the lEndpointBehavior behavior to add the parameter inspector to the Dispatcher. DispatchOperation.Parameterlnspectors method.
D) Implement the IParameterlnspector interface.
E) Implement the ICIientMessagelnspector interface.
F) Insert a code segment that creates a behavior in the ICallContextlnitializer.BeforelnvokeO method.

5. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will contain an enumeration named OrderState.
The OrderState enumeration will contain the following four values:
The client application must be able to set the state of an Order entity to only the following two values:
You need to create the data contract for OrderState. Which code segment should you use?

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