[单项选择] You create a Windows Communication Foundation (WCF) service and deploy it with wsHttpBinding and message security enabled.You create an intermediate WCF service for logging messages sent to the primary service.The intermediate service is called via endpoint behaviour. The primary service is receiving malformed data from a client application.You need to enable inspection of the malformed data and prevent message tampering. What do you do?（）

D. Modify the binding on the intermediate service to use webHttpBinding.
[单项选择] A Windows Communication Foundation (WCF) solution exposes the following service over a TCP binding.(Line numbers are included for reference only.) 01 [ServiceContract] 02 [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)] 03 public class DataAccessService 04 { 05 [OperationContract] 06 public void PutMessage(string message) 07 { 08 MessageDatabase.PutMessage(message); 09 } 10 [OperationContract] 11 pubic string[] SearchMessages(string search) 12 { 13 return MessageDatabase.SearchMessages(search); 14 } 15 } MessageDatabase supports a limited number of concurrent executions of its methods. You need to change the service to allow up to the maximum number of executions of the methods of MessageDatabase. This should be implemented without preventing customers from connecting to the service. What should you do?（）

B. Change the service behavior as follows. [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, InstanceContextMode = InstanceContextMode.PerSession)]
C. Add a throttling behavior to the service, and configure the maxConcurrentCalls.
D. Add a throttling behavior to the service, and configure the maxConcurrentSessions.
[单项选择]A Windows Communication Foundation (WCF) service that handles corporate accounting must be changed to comply with government regulations of auditing and accountability. You need to configure the WCF service to execute under the Windows logged-on identity of the calling application.What should you do?（）

B. Within the service configuration, add a Service Authentication Manager behavior to the service, and set Service Authentication Manager Type to Impersonate.
C. Within the service configuration, add a serviceSecurityAudit behavior to the service, and set service Authorization AuditLevel to Success Or Failure.
D. Within the service configuration, add a ServiceCredentials behavior to the service, and set type to Impersonate.

B. On the OperationContractAttribute, set the ReplyAction property value to the endpoint address of the client.
C. On the client, create a proxy derived from DuplexClientBase.
D. On the client, use GetCallbackChannel.
