1.You are developing a Windows Communication Foundation (WCF) service.One of the service operations contains the following code.private static int counter = 0;[OperationContract]public void IncrementCount(){ counter++;}You need to set a service behavior that prevents two or more threads from incrementing the counter variable at the same time.Which code segment should you use to set the service behavior?（）A. [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]B. [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Single)]C. [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)]D. [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Reentrant)]

2.You are creating a Window Commnunication Foundation (WCF) service application. The application needs to service many clients and requests simultaneously. The application also needs to ensure subsequent individual client requests provide a stateful conversation. You need to configure the service to support these requirements. Which attribute should you add to the class that is implementing the service?（）A. [ServiceBehavior(lnstanceContextMode = lnstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Single)]B. [ServiceBehavior(lnstanceContextMode = lnstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Reentrant)]C. [ServiceBehavior(InstanceContextMode = lnstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple)]D. [ServiceBehavior(lnstanceContextMode = lnstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Multiple)]

3.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 DataAccessService04 {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?（）A. Change the service behavior as follows. [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]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.

4.You are developing a Windows Communication Foundation (WCF) service that does not operate on a duplex channel.You find that operations do not start until all previous operations have finished. The service hosting code contains the following lines.var service = new WarehouseService(); var host = new ServiceHost(service);You need to ensure that new operations do not wait for previous operations to finish.Which attribute should you use to decorate the service?（）A. [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Multiple)]B. [CallbackBehavior(ConcurrencyMode=ConcurrencyMode.Multiple)]C. [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Single)]D. [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Reentrant)]

The definition of a related set of managed (72) types is contained in a Management Information Base (MIB)module. Many such MIB modules are defined. For each managed object type it describes, a MIB( 73) defines not only the semantics and syntax of that managed object type, but also the method of identifying an individual instance so that multiple (74) of the same managed object type can be distinguished.
