• Question 13:

  You are creating a Windows Communication Foundation (WCF) service. You do not want to expose the internal implementation at the service layer. You need to expose the following class as a service named Arithmetic with an operation

  named Sum.

  public class Calculator

  {

  public int Add(int x, int y)

  {

  }

  }

  Which code segment should you use?

  A. [ServiceContract(Namespace="Arithmetic")] public class Calculator { [OperationContract(Action="Sum")] public int Add(int x, int y) { ..... } }
  B. [ServiceContract(ConfigurationName="Arithmetic")] public class Calculator { [OperationContract(Action="Sum")] public int Add(int x, int y) { ..... } }
  C. [ServiceContract(Name="Arithmetic")] public class Calculator { [OperationContract(Name="Sum")] public int Add(int x, int y) { .... } }
  D. [ServiceContract(Name="Arithmetic")] public class Calculator { [OperationContract(ReplyAction="Sum")] public int Add(int x, int y) { ..... } }
  C. [ServiceContract(Name="Arithmetic")] public class Calculator { [OperationContract(Name="Sum")] public int Add(int x, int y) { .... } }

• Question 14:

  Your company has an existing Windows Communication Foundation (WCF) service. The following code segment is part of the service. (Line numbers are included for reference only.)

  

  You need to ensure that AJAX client applications can access the service. Which code segment should you insert at line 02?

  

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

• Question 15:

  You have an existing Windows Communication Foundation (WCF) Web service.

  The Web service is not responding to messages larger than 64 KB.

  You need to ensure that the Web service can accept messages larger than 64 KB without generating errors.

  What should you do?

  A. Increase the value of maxReceivedMessageSize on the endpoint binding.
  B. Increase the value of maxRequestLength on the httpRuntime element.
  C. Increase the value of maxBufferSize on the endpoint binding.
  D. Increase the value of maxBufferPoolSize on the endpoint binding.
  A. Increase the value of maxReceivedMessageSize on the endpoint binding.

• Question 16:

  You are creating a Windows Communication Foundation (WCF) service that implements operations in a RESTful manner. You need to add a delete operation.

  You implement the delete method as follows.

  void DeleteItems(string id);

  You need to configure WCF to call this method when the client calls the service with the HTTP DELETE operation.

  What should you do?

  A. Add the WebInvoke(UriTemplate = "/Items/{id}", Method="DELETE") attribute to the operation.
  B. Add the HttpDelete attribute to the operation.
  C. Replace the string parameter with a RemovedActivityAction parameter.
  D. Replace the return type with RemovedActivityAction.
  A. Add the WebInvoke(UriTemplate = "/Items/{id}", Method="DELETE") attribute to the operation.

• Question 17:

  You are modifying a Windows Communication Foundation (WCF) service that issues security tokens. The service is accessible through the named pipe protocol. No endpoints are added in the service code. The configuration file for the service is as follows. (Line numbers are included for reference only.)

  

  You need to ensure that new and existing client applications can access the service through HTTP and named pipes. What should you do?

  A. Insert the following line at line 05.
  B. Insert the following line at line 05.
  C. Insert the following line at line 08.
  D. Insert the following line at line 08. < add baseAddress="net.tcp://www.contoso.com:8090" />
  C. Insert the following line at line 08.

• Question 18:

  A service implements the following contract. (Line numbers are included for reference only.)

  

  The service is implemented as follows.

  

  ContosoService uses NetMsmqBinding to listen for messages. The queue was set up to use transactions for adding and removing messages.

  You need to ensure that OperationOne and OperationTwo execute under the same transaction context when they are invoked in the same session.

  What should you do?

  A. Insert the following attribute to OperationOne on IContosoService. [TransactionFlow(TransactionFlowOption.Mandatory)] Insert the following attribute to OperationTwo on IContosoService. [TransactionFlow(TransactionFlowOption.Mandatory)]
  B. Insert the following attribute to OperationOne on ContosoService. [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = false)] Insert the following attribute to OperationTwo on ContosoService. [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete = true)]
  C. Add the following XML segment to the application config file in the system.serviceModel/bindings configuration section. Then use the NetMsmqBinding named contosoTx to listen for messages from the clients.
  D. Add the following XML segment to the application config file in the system.serviceModel/bindings configuration section. Then use the CustomBinding named contosoTx to listen for messages from the clients.
  B. Insert the following attribute to OperationOne on ContosoService.

• Question 20:

  A Windows Communication Foundation (WCF) service listens for messages at net tcpilwwwcontoso.comMMyService. It has a logical address at http/Iwwwcontosocorn)MyService The configuration for the WCF client is as follows

  bindinge"netTc pBinding"

  bindingConfiguraton-NetTc pBinding_lMyService

  contract="ServiceReference 1. IMyServce'

  name='NetTcpBinding_lllyService"/>v

  The generated configuration does not provide enough information for the client to communicate with the server.
