You are developing a Windows Communication Foundation (WCF) service to provide an in-memory cache for many Web applications. The service contract is defined as follows. (Line numbers are included for reference only.)

You need to ensure that all users share the cache.
Which code segment should you insert at line 07?

• A.[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
• B.[ServiceBehavior(TransactionlsolationLevel = IsolationLevel.ReadCoromitted)]
• C.[ServiceBehavior(TransactionlsolationLevel = IsolationLevel.RepeatableRead)]
• D.[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]

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);
• D.var channelFactory = new ChannelFactory<ITaxService>( myBinding, myEndpointAddress);

You are developing a Windows Communication Foundation (WCF) service.
The service operation takes a customer number as the only argument and returns information about the customer.
The service requires a security token in the header of the message.
You need to create a message contract for the service.
Which code segment should you use?

• A.[ServiceContract]
  public interface IService
  {
  [OperationContract]
  CustomerInformation GetCustomerInformation(Header header,
  int customerNumber);
  }
  [DataContract]
  public class CustomerInformation
  {
  .......
  }
  [MessageContract]
  public class Header { [MessageHeader] public string SecurityTag;
  }
• B.[ServiceContract]
  public interface IService {
  [OperationContract]
  CustomerInformation GetCustomerInformation( CustomerNumber request);
  }
  [DataContract]
  public class CustomerInformation { } [MessageContract] public class CustomerNumber {
  [MessageHeader]
  public string SecurityTag; [MessageBodyMember] public int CustomerNumberElement; }
• C.[ServiceContract]
  public interface IService
  {
  [OperationContract]
  CustomerInformation GetCustomerInformation(
  CustomerNumber request);
  }
  [MessageContract]
  public class CustomerInformation
  {
  ......
  }
  [MessageContract] public class CustomerNumber
  {
  [MessageHeader]
  public string SecurityTag;
  [MessageBodyMember]
  public int CustomerNumberElement;
  }
• D.[ServiceContract]
  public interface IService
  { [OperationContract]
  CustomerInformation GetCustomerInformation(Header header,
  int customerNumber);
  } [MessageContract] public class CustomerInformation { } [MessageContract] public class
  Header { [MessageHeader] public string SecurityTag; }

You are creating a client application and configuring it to call a Windows Communication
Foundation (WCF) service. When the application is deployed, it will be configured to send
all messages to a WCF routing service.
You need to ensure that the application can consume the target service after the application is deployed.
What should you do?

• A.In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the router service.
• B.In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the router service.
• C.In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the target service.
• D.In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the target service.

You have a Windows Communication Foundation (WCF) service.
The service has issues with performance when it receives messages on a specific endpoint. The service must collect the minimum number of performance counters to diagnose the message issues.
You need to configure the service.
In the web.config file for the service, what should you do?

• A.Enable the Windows Management Instrumentation (WMI) provider.
• B.Enable message logging for the endpoint.
• C.In the service configuration diagnostics section, set the value of the performancCounters property to All.
• D.In the service configuration diagnostics section, set the value of the performanceCounters property to ServiceOnly.
