DRAG DROP
You have a client application that uses an existing Windows Communication Foundation (WCF) service. The client application contains a defined EndpointAddress object named endpointAddress.
A class named ServiceClient is generated by using the Svcutil tool to invoke the WCF service. Instances of the ServiceClient class are created as follows:
ServiceClient client = new ServiceClient(CreateBinding(), endpointAddress);
The client application must meet the following requirements:
- Optimize message-level security when transporting both text files and large files. - Provide transport-level security by using the HTTPS protocol.
You need to create the code for the CreateBinding() method.
Which four code segments should you use in sequence? (To answer, move the appropriate four code segments from the list of code segments to the answer area and arrange them in the correct order.)

You develop a Windows Communication Foundation (WCF) service. It is used exclusively as an intranet application and is currently unsecured.
You need to ensure that the service meets the following requirements:
The service now must be exposed as an Internet application.
The service must be secured at the transport level.
Impersonation and delegation cannot be enabled.
What should you use?

• A. basicHttpBinding and HTTP
• B. wsHttpBinding and HTTPS
  ---
• C. wsHttpBinding and Kerberos
• D. basicHttpBinding and Kerberos

You develop a Windows Communication Foundation (WCF) service that interacts with Microsoft Message Queuing (MSMQ).
The service requires sessions. You need to create a custom binding that enables messages sent to the queue to be viewed when you are using a listener tool.
Which binding elements should you use?

• A. textMessageEncoding and msmqIntegrationTransport in this order
• B. textMessageEncoding and msmqTransport in this order
• C. msmqIntegrationTransport and textMessageEncoding in this order
• D. msmqTransport and textMessageEncoding in this order

You are creating an application that consumes a Windows Communication Foundation
(WCF) service. The service implements the IService contract. The client application contains the CallbackHandler class, which implements IServiceCallback.
You need to ensure that a client proxy is created that can communicate with the service over a duplex channel.
Which code segment should you use?

• A. Dim handler = New CallbackHandler()
  Dim clientFactory =
  New DuplexChannelFactory( Of IService)(
  GetType(CallbackHandler),
  New USDualHttpBindingO )
  Dim client = clientFactory.CreateChannel(
  New InstanceContext (handler) ,
  New EndpointAddress ("") )
• B. Dim handler = New CallbackHandler()
  Dim clientFactory =
  New DuplexChannelFactory(Of IService)(
  New WSHttpContextBinding() )
  Dim client = clientFactory.CreateChannel( New InstanceContext(handler),
  New EndpointAddress (""))
• C. Dim handler - New CallbackHandler()
  Dim clientFactory =
  New DuplexChannelFactory(Of IService)(
  GetType(CallbackHandler),
  New HSDualHttpBindingO) Dim client = clientFactory.CreateChannel( New
  EndpointAddress ("") )

You have a Windows Communication Foundation (WCF) service that accepts the following message contract.

You need to ensure that the client sends a SOAP body that is accepted by the service.
