You are creating a Windows Communication Foundation (WCF) service that accepts messages from clients when they are started. The message is defined as follows.
[MessageContract]
public class Agent
{
public string CodeName { get; set; }
public string SecretHandshake { get; set; }
}
You have the following requirements:
- The CodeName property must be sent in clear text. The service must be able to verify that the property value was not changed after being sent by the client. - The SecretHandshake property must not be sent in clear text and must be readable by the service.
What should you do?

• A. Add a MessageBodyMember attribute to the CodeName property and set the ProtectionLevel to Sign. Add a MessageBodyMember attribute to the SecretHandshake property and set the ProtectionLevel to EncryptAndSign.
• B. Add an ImmutableObject attribute to the CodeName property and set its value property to true. Add a Browsable attribute to the SecretHandshake property and set its value to false.
• C. Add an XmlText attribute to the CodeName property and set the DataType property to Signed. Add a PasswordPropertyText attribute to the SecretHandshake property and set its value to true.
• D. Add a DataProtectionPermission attribute to the each property and set the ProtectData property to true.

You develop an ASP.NET web application that is hosted in the virtual directory named SecureApp. The web application uses the ASP.NET membership provider.
The application pool for the website uses the dedicated domain account named MyDomain\WebServiceAccount. The web.config file contains the connectionStrings element.
You need to secure the connectionStrings element for the web application.
Which of the following two commands must you run at a command prompt? (Each correct answer presents part of the solution. Choose two.)

• A. aspnet_regiis -pe "connectionStrings" -app "/SecureApp"
• B. aspnet_regiis -pa "NetFrameworkConfigurationKey" "MyDomain\WebServiceAccount"
• C. aspnet_regsql -pa "NetFrameworkConfigurationKey" "MyDomain\WebServiceAccount"
• D. aspnet_regiis -pe "connectionStrings" -app "MyDomain\WebServiceAccount"

You want to debug the Windows Communication Foundation (WCF) client and server interaction through message and application tracing.
You need to correlate traces generated on the client and the server.
Which XML segment should you add to the system. diagnostics configuration element in the client and server application configuration file?

• A. <sources>
  <source names"System. ServiceModel" switchValues'VerboseActivityTracing"> <listeners>
  <add namee"ServiceModelTraceListener" /> </listeners> </source>
  </sources>
• B. <sources> <source propagate Activitye'true" namee"System Service Model"
  switchValues'Warning, ActivityTracing'> <listeners
  <add namez"ServiceModelTraceListener" /> </listeners>
  </source> </sources>
• C. <sources> <source names" System ServiceModel. MessageLogging"
  switchValuee"Verbose"> <listeners>
  <add namez"ServiceModelTraceListener" /> <Listeners>
  </source> </sources>
• D. <sources>
  <source names"System. ServiceModeiMessageLogging" propagateActivitye'true" switch Values' Warning, ActivityTracing'5 <listeners> <add name="ServiceModelTraceListener" I> </listeners> </source> </sources>

You are creating a Windows Communication Foundation (WCF) service. The service endpoints change frequently.
On the service, you add a new ServiceDiscoveryBehavior to the Behaviors collection of the ServiceHost Description property.
You need to ensure that client applications can communicate with the service and discover changes to the service endpoints.
What should you do?

• A. Use the FindCriteria class and the UdpDiscoveryEndpoint class to set up the binding in the client application.
• B. Use the DiscoveryProxy class and the EndpointDiscoveryMetadata class to set up the binding in the client application.
• C. Add a new ServiceDiscoveryBehavior to the Behaviors collection in the client application.
• D. Add a new AnnouncementClient to the Behaviors collection in the client application.

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