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 have successfully created two interfaces: IMyService and IMyServiceClient.
You need to ensure that the service is able to call methods from the client application by using the IMyServiceClient interface.
Which code segment should you use?

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

2. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be hosted in a managed Console application.
The service endpoint has an address that is relative to the base address of the service.
You need to programmatically add the base address to the service.
What should you do?

A) Call an AddServiceEndpoint method of the ServiceHost class.
B) Call a constructor of the ServiceHost class.
C) Create and add a custom operation behavior to the service.
D) Create and add a custom endpoint behavior to the service.

3. You are creating a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5. The service has a contract named IMyService.
You need to ensure that the service uses an XMLSerializer object.
Which code segment should you use?

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

4. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract.
[ServiceContract]
public interface IMyService
{
[OperationContract]
void DoSomething();
}
The service will not use any external resources.
You need to ensure that the calls to the DoSomething operation are thread-safe.
What are the two possible service implementations that you can use to achieve this goal?
(Each correct answer presents a complete solution. Choose two.)

A) [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
InstanceContextMode=InstanceContextMode.PerCall)]
public class serviceImpl : MyService
{
public void DoSomething(){ }
}
B) [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
InstanceContextMode=InstanceContextMode.PerSession)]
public class serviceImpl : MyService
{
public void DoSomething(){ }
}
C) [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
InstanceContextMode=InstanceContextMode.Single)]
public class serviceImpl : MyService
{
public void DoSomething(){ }
}
D) [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Single,
InstanceContextMode=InstanceContextMode.Single)]
public class serviceImpl : MyService
{
public void DoSomething(){ }
}

5. You create a Windows Communication Foundation (WCF) service by using Microsoft .NET framework 3.5.
You write the following code segment for a service contract.
[ServiceContract]
public interface IOrderManager
{
[OperationContract]
void ProcessOrder(int ordered);
}
You need to ensure that the WCF service meets the following requirements:
Which method implementation should you use?

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