You are creating a Windows Communication Foundation (WCF) service.
You need to ensure that the service is compatible with ASP.NET to make use of the session state.
Which binding should you use?

• A.NetTcp ContextBinding
• B.NetTcp Binding
• C.NetMsmqBinding
• D.BasicHttpContextBinding

A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract] public class ContoaServicea { [OperationContract] [TransactionFlow(TransactionFlowOperation. Mandatory)]
[OperationBehavior(TraisactionScopeRequired true,
TransactionAutoCorrolete = false)
void TxOp 1 (string value) { ) [OperationCortract(lsTerminating-true)J
[TransactionFlow(TransactionFlowOption Mandatory)] [OperationBehavior(TraisactionScopeRequired true,
TransationAutoCormplete = false)]
void TxOp2(string value) {.. OperationContext. Current. SetTransactionCompleteO;
)
)
The rvice and the clients that call the service use NetTcpBinding with transaction flow enabled
You need to configure the service so that when TxOpl and TxOp2 are invoked under the same client session, they run under the same transaction context.
What should you do?

• A.Update the service contract to read as follows.
  [ServiceContract(SessionMode = SessionModeAllowed)] Add the following behavior to the
  service implementation.
  [ServiceBehavior(LnstanceContextMode = Instance ContextMode Single,
  ReleaseServicelnstanceQnTransactionComplete false)]
• B.Update the service contract to read as follows
  [ServiceContract(SessionMode = SessionMode.Allowed)] Add the following behavior to the
  service implementation.
  [ServiceBehavior(lnstanceContextMode Instance ContextMode. Single)]
• C.Update the service contract to read as follows.
  [ServiceContract(SessionMode = SessionMode.Required)]Md the following behavior to the
  service implementation.
  [ServiceBehavior(lnstanceContextMode = lnstanceContextMode. PerCall)]
• D.Update the service contract to read as follows.
  (ServiceContract(SessionMode SessionMode Required)J Add the following behavior to the
  service implementation
  [ServiceBehavior(lnstanceCoritextMode = Instance ContextMode. PerSession)]

You create a service and deploy it on a network in a building named Building1. You will deploy the service to Building2.
The service in Building1 is configured using the following discovery scopes.

The service in Building2 will be configured using the following discovery scopes.

You need to ensure that the client application can discover the service in Building1 or the service in Building2.
Which scopes should you add to the client configuration file?

• A.<scopes>
  <add
  scope="ldap:///ou=Building,ou=Chicago,o=contoso,c=us"/>
  </scopes>
• B.<scopes>
  <add scope="http://contoso.com/Chicago"/>
  </scopes>
• C.<scopes>
  <add scope="http://contoso.com/Chicago/*"/>
  </scopes>
• D.<scopes>
  <add
  scope="ldap:///ou=*,o=contoso,c=us"/>
  </scopes>

A Windows Communication Foundation (WCF) solution uses the following contracts. (Line numbers are included for reference only.)

When the client calls GetMessage on the service interface, the service calls GetName on the client callback.
In the client, the class NameService implements the callback contract.
The client channel is created as follows.

You need to ensure that the service callback is processed by the instance of NameService.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A.Change line 25 to the following code segment.
  Dim factory As DuplexChannelFactory(Of IGreetingService) =
  New DuplexChannelFactory(Of IGreetingService)(
  callbackContext, binding, address)
• B.Change line 26 to the following code segment.
  Dim greetingService As IGreetingService =
  factory.CreateChannel(callbackContext)
• C.Add the following code segment after line 26.
  callbackContext.IncomingChannels.Add(
  DirectCast(greetingService, IDuplexChannel))
• D.Add the following code segment after line 26.
  callbackContext.OutgoingChannels.Add(
  DirectCast(greetingService, IDuplexChannel))

You are developing a Windows Communication Foundation (WCF) service to replace an existing A5MX Web service.
The WCF service contains the following code segment. (Line numbers are included for reference only.)

The existing Web service returns the EmployeeID as an attribute of the EmployeeInfo element in the response XML.
You need to ensure that applications can consume the service without code changes in the client.

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