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 ensure that data sent in a SOAP header is in the following XML format.
<Data> <string>String 1</string> <string>String 2</string> <string>String 3</string>
</Data>
Which code segment should you use?

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

2. You create a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service accepts service requests from different partner applications. One of the partner applications occasionally receives faults. You need to identify why the service is generating faults. You must accomplish this goal without interrupting the service. What should you do?

A) Run SvcTraceViewer.exe /register on the WCF server.
B) Configure the Service Tracing options in the application configuration file. Analyze the
trace results by using the SvcTraceViewer.exe program.
C) Connect remotely to the WCF service by using a debugger. Place breakpoints in the
exception handling code segment.
D) Add the following code segment to the application configuration file.
<system.diagnostics>
<switches>
<add name="WcfFaultTrace" value="Error" />
</ switches>
</system.diagnostics>

3. You are creating a Windows Communication Foundation distributed application by using Microsoft .NET Framework 3.5. You write the following code segment to implement the service contract. (Line numbers are included for reference only.)

You need to ensure that the client applications of only those users who belong to the Administrators group can access the RemoveOrder method.
Which code segment should you insert at line 05?

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

4. 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.
result.AsyncWaitHandle.WaitOne(); int count=(result as DocumentServiceClient).
EndDeleteDocument(result);
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(res)
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();

5. You are creating a remote database management application by using Microsoft Windows Forms and Microsoft .NET Framework 3.5. You use the Windows Communication Foundation model to create the application.
You write the following code segment. (Line numbers are included for reference only.)

You need to ensure that each time a client application calls the Open() method, a new service instance is created.
Which code segment should you insert at line 03?

A) <OperationBehavior( _ ReleaseInstanceMode:=ReleaseInstanceMode.BeforeCall)> _
B) <OperationBehavior( _ ReleaseInstanceMode:=ReleaseInstanceMode.None)> _
C) <OperationBehavior(AutoDisposeParameters:=True)> _
D) <OperationBehavior(TransactionScopeRequired:=True)> _
