End Class
You need to ensure that only those client applications that meet the following criteria can access the RemoveOrder method:
What should you do?

A. Option A
B. Option C
C. Option D
D. Option B

Question 2

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service that will be consumed by an ASP. NET application. The WCF application and the ASP.NET application will be deployed on the same server. You need to ensure that the WCF service meets the following requirements:
The communication between the applications incurs minimum latency. The binding satisfies the ordered delivery constraint that is specified in the service implementation by using the DeliveryRequirements attribute.
Which binding object should you use?

A. NetTcpBinding
B. NetPeerTcpBinding
C. NetNamedPipeBinding
D. WSHttpBinding

Question 3

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following code segment.

Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.)

A. Create a custom endpoint behavior. Add the message inspector by using the IEndpointBehavior.ApplyClientBehavior method.
B. Create a message inspector. Insert the custom headers by using the ICIientMessagelnspector.AfterReceiveReply method.
C. Create a message inspector. Insert the custom headers by using the ICIientMessagelnspector.BeforeSendRequest method.
D. Create a custom endpoint behavior. Add the message inspector by using the IEndpointBehavior.AddBindingParameters method.

Question 5

You are creating a Windows Communication Foundation (WCF) client application by using Microsoft .NET Framework 3.5.
The WCF application is hosted in a Windows service. The service uses the LocalSystem account. The application uses Message Security with Windows credentials.
You need to ensure that the application does not negotiate the authentication protocol.
Which endpoint identity settings should you apply?

A. <identity>
<certificateReference findValue="Thumbprint of certificate is here"
storeLocation="LocalMachine"
x509FindType="FindByThumbprint"
storeName="TrustedPeople"/>
</identity>
B. <identity>
<userPrincipalName value="LocalSystem"/>
</identity>
C .<identity>
