Microsoft 070-503 Exam Syllabus Topics:

Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

1. You are creating a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation service. To log the called service proxy methods and their parameters, you implement custom endpoint behavior in the following class.
class ParametersLoggerBehavior: lEndpointBehavior
{}
You also create the following class for the custom behavior.
class LoggerElement
: BehaviorExtensionElement {}
You add the following configuration code fragment to the application configuration file.
(Line numbers are included for reference only.)

You need to ensure that the endpoint uses the custom behavior. Which configuration settings should you insert at line 03?

A) <debugBehavior name="debug" />
B) <ParametersLoggerBehavior name="debug"> <debugBehavior /> </ParametersLoggerBehavior>
C) <behavior name="debug"> <debugBehavior /> </behavior>
D) <behavior name="debug"> <ParametersLoggerBehavior /> </behavior>

2. 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.
[ServiceContract]
interface IDocumentService
{
[OperationContract]
int DeleteDocument(int id);
}
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.)
01 static void Main() 02 {
03 DocumentServiceClient client= new DocumentServiceClient();
05 }
06 static void ProcessDeleteDocument(IAsyncResult result)
07 {
06 ...
09 }
You need to ensure that the service methods are called asynchronously.
What should you do?

A) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
int count=(result.AsyncState as Documentserviceclient).EndDeleteDocument(null);
B) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
int count=(result.AsyncState as Documentserviceclient).EndDeleteDocument(result);
C) Insert the following code segment at line 04:
client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
Insert the following code segment at line 06:
result.AsyncWaitHandle.WaitOne();
int count=(result as Documentserviceclient).EndDeleteDocument(result)
D) Insert the following code segment at line 04:
IAsyncresult result = client.BeginDeleteDocument(20, ProcessDeleteDocument, client);
int count=client.EndDeleteDocument(result);
Insert the following code segment at line 06:
result.AsyncWaitHandle.WaitOne();

3. You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5.
The client application consumes the Web Services Enhancements (WSE) 3.0 Web service.
The Web service uses standard WSE 3.0 to transfer binary data to the client application.
The client application uses the following binding configuration.
(Line numbers are included for reference only.)

You need to ensure that the client application receives binary data from the WSE 3.0 Web service.
Which code fragment should you insert at line 03?

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

You need to ensure that existing client applications are still able to access the IMyService.DoSomething method without modifying client code.
Which code segment should you use?

A) Option B
B) Option D
