You are creating a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5.
The service will be hosted in a Windows Service environment. You need to create a Windows Service class that instantiates a service host.
Which code segment should you use?

• A. Option A
• B. Option B
• C. Option C
• D. Option D

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
Implements lEndpointBehavior End Class
You also create the following class for the custom behavior.
Class LoggerElement
Inherits BehaviorExtensionElement End Class
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. Option A
• B. Option B
• C. Option C
• D. Option D

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You add the following code fragment to the app.config file for the service.

You need to enable personal identifiable information (PII) logging for the second trace source.
What should you do?

• A. Set the logKnownPii attribute to true for the second source in the code fragment.
• B. Set the logKnownPii attribute to false for the first source in the code fragment.
• C. Set the logKnownPii attribute to true for the first source in the code fragment.
• D. Rename the second source listener name to Pii.

You are creating a client application that will call a Windows Communication Foundation service. The service was created by using Microsoft .NET Framework 3.5.
You write the following code segment.
[DataContract]
public class CreditCard {
private string cardNumber = 0; [DataMember] public string Name { get; set; } [DataMember] public string CardNumber { get { return cardNumber; } set { if (!IsValidCreditCardNumber(value)) { throw new ArgumentException("Invalid credit card number"); } cardNumber = value; } }
} You plan to share the validation logic between the client application and the WCF service.
You need to generate a client-side service proxy that includes the validation logic.
Which four tasks should you perform? (Each correct answer presents part of the solution. Choose four.)

• A. In the Client project, use the Add Reference dialog box to add a project reference to the Service project.
• B. Create a Class Library project for the DataContract classes.
• C. In the Client project, use the Add Service Reference dialog box to reference the service.
• D. In the Client project, use the Add Web Reference dialog box to reference the service.
• E. In the Client project, add a reference to the Class Library project.
• F. In the Service project, add a reference to the Class Library project.

You are creating a client application by using Microsoft .NET Framework 3.5. The client application will consume a COM+ application by using the Windows Communication Foundation service.
You write the following code segment to implement the COM+ application.

You need to configure the WCF service to access the COM+ application from the WCF client application.
Which code fragment should you use?

• A. Option A
• B. Option B
• C. Option C
• D. Option D
