Microsoft 070-513 Exam Syllabus Topics:

Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 Sample Questions:

1. You are developing a client application that consumes a Windows Communication Foundation (WCF) service.
You use the svcutil.exe utility to create a proxy for the service.
You use the svcutil.exe switches that generate asynchronous calls. GetFlight is a service operation that takes no parameters and returns a string. The GetFlightCallback method must be called when the service operation returns.
You create an instance of the client proxy with the following code.
var client = new TravelServiceClient();
You need to ensure that a callback is received when the GetFlight operation is called asynchronously.
Which code segment should you use?

A) client.GetFlight(); client.BeginGetFlight(GetFlightCallback, null);
B) IAsyncResult asyncResult = client.BeginGetFlight( GetFlightCallback, client); client.EndGetFlight(asyncResult);
C) client.BeginGetFlight(GetFlightCallback, null); client.GetFlight();
D) client.GetFlightCompleted += new EventHandler<GetFlightCompletedEventArgs>( GetFlightCallback); client.GetFlightAsync();

2. You are developing a Windows Communication Foundation (WCF) service that contains the following service contract.
<ServiceContract() > Public Interface IPaymentService <OperationContract() > Sub RecordPayments(ByVal person As Person) End Interface Public Class Person End Class Public Class Employee Inherits Person End Class Public Class Customer Inherits Person End Class
You need to ensure that RecordPayments can correctly deserialize into an Employee or a Customer object.
What should you do?

A) Add the following KnownType attributes to the Person class. <KnownType(GetType(Employee))> <KnownType(GetType(Customer))>
B) Implement the IExtension(Of T) interface in the Person class.
C) Add the following KnownType attribute to the Employee class and to the Customer class. <KnownType(GetType(Person))>
D) Implement the IExtensibleDataObject interface in the Person class.

3. You are developing a Windows Communication Foundation (WCF) service that does not operate on a duplex channel.
You find that operations do not start until all previous operations have finished. The service hosting code contains the following lines.
var service = new WarehouseService();
var host = new ServiceHost(service);
You need to ensure that new operations do not wait for previous operations to finish.
Which attribute should you use to decorate the service?

A) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Single) ]
B) [CallbackBehavior(
ConcurrencyMode = ConcurrencyMode.Multiple) ]
C) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Multiple)]
D) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Reentrant) ]

4. You are developing a Windows Communication Foundation (WCF) service.
One of the service operations contains the following code.
private static int counter = 0;
[OperationContract]
public void IncrementCount()
[
counter++;
}
You need to set a service behavior that prevents two or more threads from incrementing the counter variable at the same time.
Which code segment should you use to set the service behavior?

A) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Single)]
B) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.Single,
ConcurrencyMode = ConcurrencyMode.Hultiple)]
C) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.PerCall,
ConcurrencyMode = ConcurrencyMode.Reentrant)]
D) [ServiceBehavior(
InstanceContextMode = InstanceContextMode.PerSession,
ConcurrencyMode = ConcurrencyMode.Single)]

5. You are developing a Windows Communication Foundation (WCF) service.
You must record all available information for the first 1,000 messages processed, even if they are malformed.
You need to configure the message logging section of the configuration file. Which configuration segment should you use?

A) Option B
B) Option D
C) Option C
D) Option
