You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. Client applications that run on different platforms access the WCF service.
These applications transmit confidential data to the WCF service. You write the following binding configuration.
....
<binding name="TransportSecurity" >
<security mode="Transport" />
</binding>
...
You need to configure the service for optimum interoperability and optimum security.
Which code fragment should you use?

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

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to ensure that the service logs only messages that do not conform to the message contract.
Which code fragment should you use?

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

You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5. You add the following code segment to a service contract.

The DeleteDocument method in the service contract takes a long time to execute. The client application stops responding until the method finishes execution.
You write the following code segment to create an instance of a service proxy in the client application. (Line numbers are included for reference only.)

You need to ensure that the service methods are called asynchronously. What should you do?

• A.Insert the following code segment at line 05.
  IAsyncResult result= client.BeginDeleteDocument(20, ProcessDeleteDocument, client);int
  count=client.EndDeleteDocument(result);
  Insert the following code segment at 09.
  result.AsyncWaitHandle.WaitOne();
• B.Insert the following code segment at line 05.
  client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
  Insert the following code segment at line 09.
  count=(result.AsyncState as DocumentServiceClient). EndDeleteDocument(res)
• C.Insert the following code segment at line 05.
  client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
  Insert the following code segment at line 09.
  count=(result.AsyncState as DocumentServiceClient). EndDeleteDocument(nul)
• D.Insert the following code segment at line 05.
  client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
  Insert the following code segment at line 09.
  result.AsyncWaitHandle.WaitOne(); int count=(result as DocumentServiceClient).
  EndDeleteDocument(result);

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. You are designing a data contract for a Windows Communication foundation (WCF) service that will be hosted by the application. You need to ensure that the data contract meets the following requirements: It does not support Schema versioning.
It allows additional contract and additional elements to be included over time. It allows the client applications to submit messages that contain additional elements without error.
What should you do?

• A.Use the DataMemberAttribute attribute.
• B.Implement the IExtensibleDataObject interface.
• C.Implement the IMetadataExchange interface.
• D.Use the IsRequired property.

You are creating a distributed application with Windows Communication Foundation by using Microsoft .NET Framework 3.5.
The distributed application topology includes client applications, routers, and services. Communication between the client applications and the services require authentication, confidentiality, and integrity.
You need to ensure that routers are not able to read the contents of the messages. You must achieve this goal without customizing the binding configuration.
Which binding should you use?

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