QUESTION NO: 7
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 the clientVia endpoint behavior.

A. Modify the binding on the intermediate service to use netNamedPipeBinding. B. Specify a protection level of Sign in the service contract for the intermediate service. Disable transport security from the client application configuration file. C. Modify the binding on the intermediate service to use webHttpBinding. D. Specify a protection level of None in the service contract for the intermediate service. Disable message and transport security from the client application configuration file.

QUESTION NO: 9
A Windows Communication Foundation (WCF) solution uses the following contract to share a message across its clients. (Line numbers are included for reference only.)

The code for the service class is as follows.

The service is self-hosted. The hosting code is as follows.

You need to ensure that all clients calling GetMessage will retrieve the updated string if the message is updated by any client calling PutMessage.
What should you do?

A. Add the following attribute to the TeamMessageService class, before line 10.
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] B. Redefine the message string in line 13, as follows.
static string message = "Today' s Message";
Then change the implementation of PutMessage in lines 19-22 to the following.
public void PutMessage(string message) {
TeamMessageService.message = message; > C. Add the following attribute to the TeamMessageService class, before line 10.
[ServiceBehavior(InstanceContextMode =
InstanceContextMode.PecSession) ]

You have a client application that consumes a Windows Communication Foundation (WCF) service. The service contains a class named RegistrationService. The RegistrationService class contains two methods named SubmitRegistration and GetRegistrations.
The service has the following requirements:
- The client application must call the SubmitRegistration method synchronously.
- The client application must call the GetRegistrations method asynchronously.
You need to complete the client-side code to call the WCF service.
