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

1. You are creating a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application.
The distributed application contains client applications and a WCF service.
The client applications send e-mail address claims to the WCF service. The custom authorization manager of the service examines whether the claims are of the type "http://contoso.com/ClaimTypes/UserStatus".
You write the following code segment. (Line numbers are included for reference only.)

You need to map the claim types that are provided by the client applications to the claim types that are expected by the custom authorization manager of the service.
Which code segment should you insert at line 17?

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

2. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract.
[ServiceContract]
public interface IMath
{
[OperationContract]
int Add(int num1, int num2);
}
You need to add an operation contract to perform the Add operation asynchronously. Which operation contract should you use?

A) [OperationContract(AsyncPattern=true)]IAsyncResult BeginAdd(int num1, int num2);int EndAdd (IAsyncResult res);
B) [OperationContract]IAsyncResult BeginAdd(int num1, int num2);[OperationContract]int EndAdd (IAsyncResult res);
C) [OperationContract(AsyncPattern=true)]IAsyncResult BeginAdd(int num1, int num2,
AsyncCallback cb,
object state);int EndAdd(IAsyncResult res);
D) [OperationContract]int BeginAdd(int num1, int num2, AsyncCallback cb, object state);IAsyncResult EndAdd ();

3. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
The service contains the following code segment.
[ServiceContract]
public interface IMathSrvc
{
[OperationContract]
void AddNumbers(int num);
[OperationContract]
int Clear();
}
You need to ensure that the service meets the following requirements:
Which code segment should you use to replace the existing code segment?

A) [ServiceContract]
public interface IMathSrvc
{
[OperationContract(IsTerminating=false)]
void AddNumbers(int num);
[OperationContract(IsTerminating=true)]
int Clear();
}
B) [ServiceContract]
public interface IMathSrvc
{
[OperationContract]
void AddNumbers(int num);
[OperationContract(IsInitiating=false, IsTerminating=true)]
int Clear();
}
C) [ServiceContract]
public interface IMathSrvc
{
[OperationContract(IsOneWay=true)]
void AddNumbers(int num);
[OperationContract(IsTerminating=true)]
int Clear();
}
D) [ServiceContract]
public interface IMathSrvc
{
[OperationContract(IsInitiating=true, IsOneWay=true)]
void AddNumbers(int num);
[OperationContract(IsTerminating=true)]
int Clear();
}

4. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You create the following service definition.
<ServiceContractQ> _ Public Interface IMyService ... End Interface
You need to custom manage the lifetime of the session.
Which service implementation should you use?

A) <ServiceBehavior(UseSynchronizationContext:=True)> _
Public Class Servicelmp1
...
End Class
B) <ServiceBehavior(UseSynchronizationContext:=False)> _
Public Class ServicelmpID
...
End Class
C) <ServiceBehavior(AutomaticSessionShutdown:=False)> _
Public Class Servicelmp1
...
End Class
D) <ServiceBehavior(AutomaticSessionShutdown:=True)> _
Public Class Servicelmp1
...
End Class

5. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.)
01 <SetviceContract(SessionMode:=SessionMode.Required)> _
02 Public Interface lOrderManager 04 Sub CloseOrder()
05 End Interface
You need to decorate the operation as the method that closes the current session.
Which code segment should you insert at line 03?

A) <OperationContract(lslnitiating:=False)> _
B) <OperationContract(lsTerminating:=True)> _
C) <OperationContract(lsTerminating:=False)> _

ReleaselnstanceMode:=ReleaselnstanceMode.AfterCall>
D) <OperationContract()> _
<OperationBehavior(_
ReleaselnstanceMode:=ReleaselnstanceMode.AfterCall)>_
