Microsoft 70-503 Value Pack (Frequently Bought Together)

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment.
namespace MyServices
{
[ServiceContract()]
interface IManageOrders
{
...
}}
The service metadata must be exposed at the relative address named meta.
You need to add an endpoint element to the app.config file of the service host. Which code
fragment should you add?

• A. <endpoint address="meta" binding="wsHttpBinding" contract="MyServices.IMetadataExchange" />
• B. <endpoint address="meta" binding="wsHttpBinding" contract="IManageOrders" />
• C. <endpoint address="meta" binding="mexHttpBinding" contract="IMetadataExchange" />
• D. <endpoint address="meta" binding="mexHttpBinding" contract="MyServices.IManageOrders" />

You create a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation (WCF) service. You plan to Implement inspection handling on the client application and the WCF service. You need to add error handling to the WCF service.
What should you do?

• A. Modify the AfterReceiveRequest method to catch the ReplyValidationFault exception. Replace the reply message with an explicit fault message.
• B. Modify the AfterReceiveReply method to catch the ReplyValidationFault exception. Replace the reply message with an explicit fault message.
• C. Modify the BeforeSendRequest method to catch the ReplyValidationFault exception. Replace the reply message with an explicit fault message.
• D. Modify the BeforeSendReply method to catch the ReplyValidationFault exception. Replace the reply message with an explicit fault message.

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

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You define the following data contract.

You need to identify the structure of the resulting XML instance document. Which structure will the data contract produce?

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

You are creating a client application by using Microsoft .NET Framework 3.5. The client application will consume a COM+ application by using the Windows Communication Foundation service. You write the following code segment to implement the COM+ application.

The application ID of the COM+ application is {AppGuidlsHere}.
You need to configure the WCF service to access the COM+ application from the WCF client application. Which code fragment should you use?

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