You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
The WCF service must authenticate the client applications by validating credit card numbers and expiry dates. You write the following code segment. (Line numbers are included for reference only.)
01 class CreditCardTokenAuthenticator: SecurityTokenAuthenticator
02 {
03 // Implementation of other abstract methods comes here.
04 protected override ReadOnlyCollection<IAuthorizationPolicy> ValidateTokenCore(SecurityToken token)
05 {
06 CreditCardToken creditCardToken = token as CreditCardToken;
07 }
09 private bool IsCardValid(string cardNumber, 13 DateTime expirationDate)
10 {
11 // Validation code comes here.
12 }
13 }
You need to implement custom authentication for the WCF service. Which code segment should you insert at line 07?

You are creating a distributed application with Windows Communication Foundation by using Microsoft .NET Framework 3.5.
The distributed application topology includes client applications, routers, and services. Communication between the client applications and the services require authentication, confidentiality, and integrity.
You need to ensure that routers are not able to read the contents of the messages. You must achieve this goal without customizing the binding configuration.
Which binding should you use?

You create a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation (WCF) service.
The WCF service analyzes incoming message headers to verify whether special processing of the message is required.
The client application accompanies each call to the methods of the service with the address header.
You write the following code segment. (Line numbers are included for reference only.)
You need to ensure that the following requirements are met:
The client application makes a second call to the FindPhoneByAddress method.
The message header of the second call is presented by a variable named newHeader.
Which code segment should you insert at line 11?
