You create a Windows Communication Foundation (WCF) application by using Microsoft Visual Studio 2008 and the .NET Framework 3.5. You create a WCF service by using the following code segment. (Line numbers are included for reference only.)
01 [ServiceContract]
02 public interface IContosoService
03 {
04 [OperationContract]
06 void ProcessTransaction();
07 }
09 public class ContosoService : IContosoService
10 {
11 public void ProcessTransaction() {
12 try {
13 BusinessComponent.ProcessTransaction();
14 }
15 catch (ApplicationException appEx) {
17 }
18 }
19 }
The BusinessComponent.ProcessTransaction method will only throw exceptions from the ApplicationException type. You plan to debug the WCF service. You need to ensure that the WCF service meets the following requirements:
Detailed exception information is provided to the client application. Subsequent calls can be issued to the service by using the same proxy intance after an exception is caught in the client application. What should you do?

• A. Add the following code segment at line 08.
  [ServiceBehavior(IncludeExceptionDetailInFaults=true)] Add the following code segment at
  line 16. throw new FaultException<ApplicationException>(appEx);
• B. Add the following code segment at line 05. [FaultContract(typeof(ApplicationException))]
  Add the following code segment at line 16. throw new
  FaultException<ApplicationException>(appEx);
• C. Add the following code segment at line 08.
  [ServiceBehavior(IncludeExceptionDetailInFaults=true)] Add the following code segment at
  line 16. throw appEx;
• D. Add the following code segment at line 05. [FaultContract(typeof(ApplicationException))]
  Add the following
  code segment at line 16. throw appEx;

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You configure a binding to enable streaming.
You need to ensure that the client application is able to stream large XML files to the WCF service.
Which operation contract should you create?

• A. <OperationContractQ> _ Sub UploadFile(ByVal xmlData As XmlWriter)
• B. <OperationContractQ> _ Sub UploadFile(ByVal xmlData As Stream)
• C. <OperationContractQ> _ Sub UploadFile(ByVal xmlData As StreamWriter)
• D. <OperationContractQ> _ Sub UploadFile(ByVal xmlData As ByteQ)

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following code segment.

You need to ensure that the service instance is recycled when the transaction is complete. Which line of code should you insert at line 06?

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

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You need to use a custom service host to host the WCF service in Windows Activation Services (WAS).
What should you do?

• A. Add code to instantiate the custom service host from within the main procedure of the WCF service.
• B. Add a reference to the custom service host in the web.config file.
• C. Create a custom service host factory that instantiates the custom service host. Include a reference to this factory in the .svc file.
• D. Write hosting code for the WCF service.

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to configure a single service endpoint with the following logical and physical addresses:
Which configuration setting should you use?

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