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.
The service contains the following code segment
[ServiceContract]
public interface IMyService
{
[OperationContract(IsOneWay=true, ProtectionLevel=ProtectionLevel.None)]
[TransactionFlow(TransactionFlowOption.Allowed)]
void DoSomething();
}
You need to ensure that the DoSomething operation can participate in transactions.
Which code segment should you use to replace the existing operation contract?

A) [OperationContract(IsOneWay=true, ProtectionLevel=ProtectionLevel.Sign)]
[TransactionFlow(TransactionFlowOption.Mandatorv)]
void DoSomething();
B) [OperationContract(ProtectionLevel= ProtectionLevel.EncryptAndSign)]
[TransactionFlow(TransactionFlowOption.NotAllowed)]
void DoSomething();
C) [OperationContract(ProtectionLevel=ProtectionLevel.None)]
[TransactionFlow(TransactionFlowOption.Allowed)]
void DoSomething();
D) [OperationContract(IsOneWay=true,
ProtectionLevel=ProtectionLevel.EncryptAndSign)]
[TransactionFlow(TransactionFlowOption.Allowed)]
void DoSomething();

2. You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment to define the service. (Line numbers are included for reference only.)

You need to set the ServiceContract attribute for the transaction behavior of the service. Which code segment should you insert at line 01?

A) <ServiceContract(SessionMode:=SessionMode.Allowed, _ ProtectionLevel:=ProtectionLevel.EncryptAndSign)> _
B) <ServiceContract(SessionMode:=SessionMode.Allowed)> _
C) <ServiceContract(SessionMode:=SessionMode.Required)> _
D) <ServiceContract(SessionMode:=SessionMode.NotAllowed, _ ProtectionLevel:=ProtectionLevel.EncryptAndSign)> _

3. You are creating a Windows Communication Foundation (WCF) client application by using Microsoft .NET Framework 3.5.
The WCF application is hosted in a Windows service. The service uses the LocalSystem account. The application uses Message Security with Windows credentials.
You need to ensure that the application does not negotiate the authentication protocol.
Which endpoint identity settings should you apply?

A) <identity>
<userPrincipalName value="LocalSystem"/>
</identity>
C .<identity>
<servicePrincipalName value="host/YourComputerName" />
</identity>
B) <identity>
<dns value="http: //YourComputerName"/>
</identity>
C) <identity>
<certificateReference findValue="Thumbprint of certificate is here"
storeLocation="LocalMachine"
x509FindType="FindByThumbprint"
storeName="TrustedPeople"/>
</identity>

4. You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
You need to host the WCF service on the IIS Web server. First, you create a new folder for your application files. Next, you use the IIS management tool to create a Web application in the new folder.
Which three actions should you perform next? (Each correct answer presents part of the solution. Choose three.)

A) Create an App_Code sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
B) Create a vti_bin sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
C) Create a service file that has the .svc extension containing the @servicehost directive information for the service. Move this file to the application folder.
D) Create a web.config file that contains the appropriate configuration code. Place this file in the application folder.
E) Create a web.config file that contains the appropriate configuration code. Place this file in the same folder as your service contract code.
F) Create a service file that has the svc extension containing the @service directive information for the service. Move this file to the application folder.

5. You are creating a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation service. To log the called service proxy methods and their parameters, you implement custom endpoint behavior in the following class.
class ParametersLoggerBehavior: lEndpointBehavior
{}
You also create the following class for the custom behavior.
class LoggerElement
: BehaviorExtensionElement {}
You add the following configuration code fragment to the application configuration file.
(Line numbers are included for reference only.)

You need to ensure that the endpoint uses the custom behavior. Which configuration settings should you insert at line 03?

A) <behavior name="debug"> <debugBehavior /> </behavior>
B) <behavior name="debug"> <ParametersLoggerBehavior /> </behavior>
C) <debugBehavior name="debug" />
D) <ParametersLoggerBehavior name="debug"> <debugBehavior /> </ParametersLoggerBehavior>
