Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:
1. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to programmatically add the following endpoint definition to the service. http://localhost:8000/Examservice/service
Which code segment should you use?
A) Option C
B) Option A
C) Option D
D) Option B
2. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to ensure that you can customize the behavior of the ClientRuntime class and the DispatchRuntime class. You must achieve this goal without altering the behavior of the service.
What should you do?
A) Implement the IContractBehavior interface to create a Contract behavior.
B) Implement the IServiceBehavior interface to create a Service behavior.
C) Implement the IOperationBehavior interface to create an Operation behavior.
D) Implement the IEndpointBehavior interface to create an Endpoint behavior.
3. 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:
result.AsyncWaitHandle.WaitOne();
int count=(result as Documentserviceclient).EndDeleteDocument(result)
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(null);
C) 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();
D) 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);
4. You are creating a Windows Communication Foundation service by using Microsoft .NET
Framework 3.5.
The service will be hosted in a Windows Service environment. You need to create a Windows Service class that instantiates a service host.
Which code segment should you use?
A) Option C
B) Option A
C) Option D
D) Option B
5. You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5.
You need to host the WCF service on the IIS Web server. First, you create a new folder for your application files. Next, you use the IIS management tool to create a Web application in the new folder.
Which three actions should you perform next? (Each correct answer presents part of the solution. Choose three.)
A) Create a web.config file that contains the appropriate configuration code. Place this file in the application folder.
B) Create a service file that has the svc extension containing the @service directive information for the service. Move this file to the application folder.
C) Create a vti_bin sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
D) Create a service file that has the .svc extension containing the @servicehost directive information for the service. Move this file to the application folder.
E) Create an App_Code sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
F) Create a web.config file that contains the appropriate configuration code. Place this file in the same folder as your service contract code.
