B. BindingElement encoding = new TextMessageEncodingBindingElement (Soap12WSAddressingAugust2004..)
C. BindingElement encoding = new TextMessageEncodingBindingElement(MessageVersion.Soap11.....)
D. BindingElement encoding = new BindingElement()

Question 5

You are creating an application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application. The YourUserNamePasswordValidator class is implemented in the host application of the WCF service. The host application is named YourServiceHost.exe. You write the following code segment.
namespace YourSecureService
{
class YourUserNamePasswordValidator : UserNamePasswordValidator {
public override void Validate(string userName, string password)
{
...
}}
}
You need to perform custom validation of the user name and password by using the YourUserNamePasswordValidator class. What should you do?

A. Set the netTcpBinding binding in the following manner. <security mode="Transport">
<transport
clientCredentialType="UserName" /></security> Set the service behavior by using the
following credentials.
<userNameAuthentication customUserNamePasswordValidatorType="YourSecureService.
YourUserNamePasswordValid ator " userNamePasswordValidationMode="Custom"/>
B. Set the wsHttpBinding binding in the following manner. <security mode="Message">
<message
clientCredentialType="UserName" /></security> Set the service behavior by using
thefollowing credentials.
<userNameAuthentication
customUserNamePasswordValidatorType="YourSecureService.YourUserNamePasswordV
alid ator"
userNamePasswordValidationMode="Custom"/>
C. Set the wsHttpBinding binding in the following manner. <security mode="Message">
<message
clientCredentialType="UserName" /></security> Set the service behavior by using the
following credentials.
<userNameAuthentication customUserNamePasswordValidatorType="YourSecureService.
YourUserNamePasswordValid a or,YourServiceHost"
userNamePasswordValidationMode="Custom"/>
D. Set the wsHttpBinding binding in the following manner. <security mode="Message">
<transport
clientCredentialType="UserName" /></security> Set the service behavior by using the
following credentials.
<userNameAuthentication
customUserNamePasswordValidatorType="YourUserNamePasswordValidator,
YourServiceHo st" userNamePasswordValidationMode="Custom"/>
