B) net.msmq://localhost/system$;DeadLetter
C) net.msmq://localhost/system$;DeadXact
D) net.msmq://localhost/msmq$;FailedMessages

2. DRAG DROP
You develop a Windows Communication Foundation (WCF) service that is hosted within a console application. The service implements the IRegistrationService interface in a class named RegistrationService. The service uses the following endpoint URL: http://localhost:8080/registrationservice/basic
You need to configure the console application to host the service.
How should you complete the relevant code? (To answer, drag the appropriate code segment to the correct location in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

3. A Windows Communication Foundation (WCF) service handles online order processing for your company.
You discover that many requests are being made with invalid account numbers. You create a class named AccountNumberValidator that has a method named Validate.
Before the message is processed, you need to validate account numbers with AccountNumberValidator and reject messages with invalid account numbers.
You create a new class that implements the IParameterInspector interface. Which code segment should you use in this class?

A) Public Sub AfterCall(
ByVal operationName As String,
ByVal outputs() As Object,
ByVal returnValue As Object,
ByVal correlationState As Object) _ Implements
IParameterInspector.AfterCall
Dim accountNumber As String = GetAccountNumber(outputs)
Dim validator As
AccountNumberValidator = New AccountNumberValidator()
If (Not validator.Validate(accountNumber)) Then
Throw New FaultException()
End If
End Sub
Public Function BeforeCall(
ByVal operationName As String,
ByVal inputs() As Object) As Object _
Implements IParameterInspector.BeforeCall
Return Nothing
End Function
B) Public Sub AfterCall(
ByVal operationName As String,
ByVal outputs() As Object,
ByVal returnValue As Object,
ByVal correlationState As
Object) _
Implements IParameterInspector.AfterCall
Return
End Sub
Public Function BeforeCall(
ByVal operationName As String,
ByVal inputs() As Object) As Object _
Implements IParameterInspector.BeforeCall
Dim accountNumber As String = GetAccountNumber(inputs)
Dim validator As AccountNumberValidator = New AccountNumberValidator() If (Not
validator.Validate(accountNumber)) Then
Throw New FaultException()
End If
Return Nothing
End Function
C) Public Sub AfterCall(
ByVal operationName As String,
ByVal outputs() As Object,
ByVal returnValue As Object,
ByVal correlationState As Object) _
Implements IParameterInspector.AfterCall
Return
End Sub
Public Function BeforeCall(
ByVal operationName As String,
ByVal inputs() As Object) As Object _
Implements IParameterInspector.BeforeCall Dim accountNumber As String =
GetAccountNumber(inputs)
Dim validator As AccountNumberValidator =
New AccountNumberValidator()
If (Not validator.Validate(accountNumber)) Then
Return New FaultException()
End If
End Function
D) Public Sub AfterCall(
ByVal operationName As String,
ByVal outputs() As Object,
ByVal returnValue As Object, ByVal correlationState As Object) _ Implements IParameterInspector.AfterCall Dim accountNumber As String = GetAccountNumber(outputs) Dim validator As AccountNumberValidator = New AccountNumberValidator() If (Not validator.Validate(accountNumber)) Then returnValue = New FaultException() End If End Sub Public Function BeforeCall( ByVal operationName As String, ByVal inputs() As Object) As Object _ Implements IParameterInspector.BeforeCall Return Nothing End Function

4. You are maintaining a Windows Communication Foundation (WCF) service that uses a custom UserNamePassword class to authenticate clients.
