You are developing a client application that uses the following code to consume a Windows Communication Foundation (WCF) service. (Line numbers are included for reference only.)
01 BasicHttpBinding myBinding = new BasicHttpBinding(); 02 EndpointAddress myEndpointAddress = new EndpointAddress( "http://contoso.com/TaxService.svc");
04 ITaxService client = channelFactory.CreateChannel();
05 string data = client.GetData(1);
You need to consume the service.
Which code segment should you insert at line 03?

• A.var channelFactory = new ChannelFactory<ITaxService>( "http://contoso.com/TaxService.svc");
• B.var channelFactory = new ChannelFactory<ITaxService>();
• C.var channelFactory = new ChannelFactory<ITaxService>( myBinding, myEndpointAddress);
• D.var channelFactory = new ChannelFactory<ITaxService>( myBinding);

The endpoint of a Windows Communication Foundation (WCF) service uses basicHttpBinding for its binding Your Company's policies have changed to require that messages not be sent in clear text.
You must ensure that all messages are encrypted when traveling across the network What should you do?

• A.Set the PrincipalPermissionAttribute on the service contract and update the bindingConfiguration attribute in the endpoint element of the configuration file to wsHttpBinding.
• B.Set the PrincipalPermissionAttribute on the service contract and update the binding attribute in the endpoint element of the configuration file to wsHttpBinding
• C.Set the ProtectionLevelAttribute on the service contract and update the bindingConfiguration attribute in the endpoint element of the configuration file to webHttpBinding
• D.Set the ProtectionLevelAttribute on the service contract and update the binding attribute in the endpoint element of the configuration file to wsHttpBinding

You are creating a Windows Communication Foundation (WCF) service that is implemented as folks. (Line numbers are included for reference only.)
01 <ServiceContract()
02<ServiceBehaior(lncludeExceptionDetailInFaults: Time)>
03Public Class OrderService

You need to ensure that the sack trace details of the exception are not included in the error information sent to the client. What should you do?

• A.After line 05, add the following line.
  <FaultContract(GetType(FaultException(CX Order)))>
  Replace line 11 with the following line.
  Throw New FaultException(CX Order)(
  anOrder, "Divide by zero exception")
• B.After line 05, add the following line.
  'cFaultContract(GetType(FautException(Of Order)))>
  Replace line 11 with the following line.
  Throw ex
• C.Replace line 11 with the following line.
  Throw
• D.Replace line 11 with the following line.
  Throw New FaultException(C Order)(anOrder, exToSthng0)d

A WCF service code is implemented as follows. (Line numbers are included for reference only)
01 [ServiceContract]
02 [ServiceBehavior(lnstanceContextMode =
03 lnstanceContextModeSingle)]
04 public class CalculatorService
05 {
06 [OperationContract]
07 public double Calculate(double op1, string op. double op2)
08 {
24 }
25 }
You need to increase the rate by which clients get the required response from the service.
What e two possible ways to achieve this goal? (Each correct answer presents a complete sokiion
Choose two.)

• A.Change the service behavior to the following.
  [ServiceBehavior(
  lnstanceContextMode = lnstanceContextModeSingle,
  ConcirrencyMode = ConcurrencyMode. Multide)]c
• B.Require the clients to use async operations when calling the senvice.
• C.Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.
• D.Change the service behavior to the following.
  [ServiceBehavior(lnstanceContextMode = lnstanceContextMode.PerCall)]

You are developing a Windows Communication Foundation (WCF) service that contains the following operation contract.
[OperationContract]
CustomerNames GetCustomerNames();
The operation returns customer names.
You need to develop a definition for the operation contract that produces XML with the following structure.

Which code segment should you use?

• A.[DataContract]
  public class CustomerNames
  {
  [DataMember]
  public string[] Names;
  }
• B.[MessageContract(WrapperName = "")]
  public class CustomerNames
  {
• C.[MessageContract(IsWrapped = false)]
  public class CustomerNames
  {
  [MessageBodyMember]
  public string[] Names;
  }
• D.[DataMember(IsRequired = false)]
  public string[] Names;
  }
• E.[MessageBodyMember]
  public string[] Names;
  }
• F.[DataContract]
  public class CustomerNames
  {
