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

HOTSPOT
You are developing a Windows Communication Foundation (WCF) service. You implement a data contract to pass complex data to and from the service. The service includes the following code:

You need to verify the order in which the data is serialized.
For each of the following statements, select True if the statement is true. Otherwise select False.

정답:

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

A WCF service code is implemented as follows. (Line numbers are included for reference only.)
01 [ServiceContract] 02 [ServiceBehavior(InstanceContextMode = 03 InstanceConcextMode.Single)]
04 public class CalculatorService
05 {
06 [OperacionContract]
07 public double Calculate(double opl, string op, double op2)
08 {
...
24 }
25 }
You need to decrease the response time of the service.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

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

DRAG DROP
You use Visual Studio to develop a Windows Communication Foundation (WCF) service. The service is not hosted.
You cannot use the WcfTestClient.exe tool to test the service.
You need to test the service from a separate Visual Studio solution that contains a simple console application.
Which four actions should you perform in sequence? (To answer, move the appropriate four actions from the list of actions to the answer area and arrange them in the correct order.)
