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 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.
• B. 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.
• C. Add a DataProtectionPermission attribute to the each property and set the ProtectData property to true.
• D. 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.

You develop a Windows Communication Foundation (WCF) service that is hosted by using
Windows Activation Services (WAS).
You need to configure the service to accept requests that use the TCP/IP protocol.
What should you do? (Each correct answer presents part of the solution. Choose two.)

• A. In Control Panel, enable the WCF Non-HTTP Activation feature.
• B. In Control Panel, enable the Windows Communication Foundation HTTP Activation feature.
• C. Run the aspnet_regiis executable to enable TCP/IP service activation.
• D. Run the appcmd executable to enable TCP/IP service activation.

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 Property CodeName As String Public Property SecretHandshake As String End Class 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 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.

A Windows Communication Foundation (WCF) service only accepts messages that are signed and encrypted a client application is not receiving expected responses from the service.
You need to enable logging to verity that the messages from the client are signed and encrypted.
You also need to see what each message looks like before the message body is deserialized into a
NET object what should you do?

• A. Configure the System. Service Model trace source in the system diagnostics
  configuration section.
  In the system.serviceModel configuration, add the following XML segment,
  <diagnostics>
  <message Logging log Entire Message="
  true log Messages t Service LeveI-true' Is
  <diagnostics>
• B. Configure the System Service Model trace source in the system diagnostics
  configuration section.
  In the system service Model configuration add the following xML segment
  <diagnostics>
  <message Logging log Entire Messages" true
  logMessagesAtServiceLeveIetrue"
  logMessagesAtTransportLeveletrue" />
  </diagnostics>
• C. Configure the System. Service Model Message Logging trace source in the system
  diagnostics
  configuration sectionIn the system. service Model configuration, add the following XML
  segment.
  <diagnostics>
  <message Logging log Entire Message='
  true Iog Messages At Service LeveI true"
  log Messages At Transport Level=true" I> <Idiagnostics>
• D. Configure the System. Service Model Message Logging trace source in the system.
  diagnostics configuration section.
  In the system service Model configuration, add the following xML segment
  <diagnostics>
  <message Logging Iog Messages At Service Levele true"
  log Messages At Transport Levele"true" 1>
  </diagnostics>
