You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract.
[ServiceContract]
public interface IMath
{
[OperationContract]
int Add(int num1, int num2);
}
You need to add an operation contract to perform the Add operation asynchronously. Which operation contract should you use?

• A. [OperationContract]IAsyncResult BeginAdd(int num1, int num2);[OperationContract]int EndAdd (IAsyncResult res);
• B. [OperationContract(AsyncPattern=true)]IAsyncResult BeginAdd(int num1, int num2);int EndAdd (IAsyncResult res);
• C. [OperationContract(AsyncPattern=true)]IAsyncResult BeginAdd(int num1, int num2,
  AsyncCallback cb,
  object state);int EndAdd(IAsyncResult res);
• D. [OperationContract]int BeginAdd(int num1, int num2, AsyncCallback cb, object state);IAsyncResult EndAdd ();

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment.

You have not deployed the IMathService service.
You need to expose the AddNumbers (a As Double, b As Double) As Double operation to
the IMathService service contract.
Which code segment should you use?

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

You are creating an application in Windows Communication Foundation (WCF) by using Microsoft.NET Framework 3.5.
You need to ensure that the client application communicates with the service by using a duplex contract.
Which five actions should you perform? (To answer, move the five appropriate actions from the list of actions to the answer area, and arrange them in the correct order.)

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service that will be consumed by an ASP. NET application. The WCF application and the ASP.NET application will be deployed on the same server. You need to ensure that the WCF service meets the following requirements:
The communication between the applications incurs minimum latency. The binding satisfies the ordered delivery constraint that is specified in the service implementation by using the DeliveryRequirements attribute.
Which binding object should you use?

• A. NetNamedPipeBinding
• B. WSHttpBinding
• C. NetPeerTcpBinding
• D. NetTcpBinding

You are creating a Windows Communication Foundation application by using Microsoft .NET Framework 3.5. The application must consume an ATOM 1.0 feed published at http://localhost:8000/BlogService/GetBlog.
You write the following code segment. (Line numbers are included for reference only.)
01 Uri address = new 02 Uri("http://localhost:8000/BlogService/GetBlog");
04 Console.WriteLine(feed.Title.Text);
You need to ensure that the application prints the title of the feed.
Which code segment should you insert at the line 03?

• A. Syndicationltem item = Syndicationltem.Load(address);
  SyndicationFeed feed = new SyndicationFeed();
  feed. Items = new Syndicationltem[] { item };
• B. SyndicationFeed feed = SyndicationFeed.Load(address);
• C. Syndicationltem item = new Syndicationltem();
  item.BaseUri = address;
  SyndicationFeed feed = new SyndicationFeed();
  feed. Items = new Syndicationltem[] { item };
• D. SyndicationFeed feed = new SyndicationFeed0;feed.BaseUri = address;
