Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 認定 70-513 試験問題：

問題 #1

A Windows Communication Foundation (WCF) service is self-hosted in a console application.
The service implements the IDataAccess contract, which is defined in the MyApplication namespace.
The service is implemented in a class named DataAccessService, which implements the IDataAccess interface and also is defined in the MyApplication namespace.
The hosting code is as follows. (Line numbers are included for reference only.)
01 static void Main(string[] args)
02 {
03 ServiceHost host;
05 host.Open();
06 Console.ReadLine();
07 host.Close();
08 }
You need to create a ServiceHost instance and assign it to the host variable. You also need to instantiate the service host.
Which line of code should you insert at line 04?

A. host = new ServiceHost(typeof(DataAccessService));
B. host = new ServiceHost("MyApplication.DataAccessService");
C. host = new ServiceHost(typeof(IDataAccess));
D. host = new ServiceHost("MyApplication.IDataAccess");

問題 #2

You are configuring services to be discoverable. The services must be discoverable without relying on a central server. Client applications that consume the services are on a network segment that is separate from the network segment that the services are located on.
A firewall blocks all TCP ports between the two network segments, but allows other protocols to pass through.
You need to ensure that the client applications can discover the services.
What should you do?

A. Use managed discovery mode over UDP.
B. Use managed discovery mode over HTTP.
C. Use ad-hoc discovery mode over HTTP.
D. Use ad-hoc discovery mode over UDP.

問題 #3

DRAG DROP
You are developing a Windows Communication Foundation (WCF) service that contains a method named ProcessPayments. The service is hosted in Internet Information Services (IIS).
You have the following requirements:
- Create a new instance of the service every time that a client application calls the ProcessPayments method. - Process every call from client applications one at a time.
You need to complete the code for the WCF service.
Which four code segments should you use in sequence? (To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.)

問題 #4

You are modifying an existing Windows Communication Foundation (WCF) service that is defined as follows.

SubmitOrder makes a call to another service. The ProcessMessage method does not perform as expected under a heavy load.
You need to enable processing of multiple messages. New messages must only be processed when the ProcessMessage method is not processing requests, or when it is waiting for calls to SubmitOrder to return.
Which attribute should you apply to the MessageProcessor class?

A. CallbackBehavior ( ConcurrencyMode = ConcurrencyMode.Multiple )
B. CallbackBehavior ( ConcurrencyMode = ConcurrencyMode.Reentrant )
C. ServiceBehavior ( ConcurrencyMode = ConcurrencyMode.Reentrant )
D. ServiceBehavior ( ConcurrencyMode = ConcurrencyMode.Multiple )

問題 #5

You are developing a client that sends several types of SOAP messages to a Windows Communication
Foundation (WCF) service method named PostData PostData is currently defined as follows
<OperationContract>
Sub PostData(Byval data As Order) You need to modify PostData so that it can receive any SOAP message.
Which code segment should you use?

A. <OperationContract0> Sub PostData(ByVal data As Message)
B. <OperationContract(lsOneWay True, Action ReplyAction '-)> Sub PostData(ByVal data As Order)
C. <OperationContract> Sub PostData(Byval data As BodyWriter)
D. OperationContract(lsOneway: zTrue, Action:z'-', ReplyAction: z"-')> Sub PostData(ByVal data As BodyWriter)
