Microsoft TS: Windows Communication Foundation velopment with Microsoft .NET Framework 4 Sample Questions:

Question 1

You are implementing a Windows Communication Foundation (WCF) service contract named IContosoService in a class named ContosoService. The service occasionally fails due to an exception being thrown at the service.
You need to send the stack trace of any unhandled exceptions to clients as a fault message.
What should you do?

A. In the application configuration file on the service and all the clients, add the following
XML segment to the system.diagnostics/sources configuration section group.
<source name="System.ServiceModel" switchValue="Error" propagateActivity="true">
<listeners>
<add name="ServiceModelTraceListener"
initializeData="app_tracelog.svclog"
type="System.Diagnostics.XmlWriterTraceListener" />
</listeners>
</source>
B. In the application configuration file on the client, add the following XML segment to the
system.serviceModel/behaviors configuration section group.
<endpointBehaviors>
<behavior name=" debug ">
< callback Debug includeExceptionDetailInFaults="true" />
</behavior>
</endpointBehaviors>
Associate the debug behavior with any endpoints that need to return exception details.
C. Apply the following attribute to the ContosoService class.
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
D. For each OperationContract exposed by IContosoService, apply the following attribute.
[FaultContract(typeof(Exception))]

Question 2

DRAG DROP
You have a client application that consumes a Windows Communication Foundation (WCF) service. The service contains a class named RegistrationService. The RegistrationService class contains two methods named SubmitRegistration and GetRegistrations.
The service has the following requirements:
- The client application must call the SubmitRegistration method synchronously.
- The client application must call the GetRegistrations method asynchronously.
You need to complete the client-side code to call the WCF service.
Which six code segments should you use in sequence? (To answer, move the appropriate six code segments from the list of code segments to the answer area and arrange them in the correct order.)

Question 3

You are developing a Windows Communication Foundation (WCF) service that executes a long-running operation.
The service is accessed from your business applications in a server transaction in which the client does not participate.
You need to ensure that the transaction times out and aborts if the operation has not completed within 45 seconds.
What should you do?

A. Apply f ServiceBehavior (TransaccionTlmeout="00:00:45")] to the service implementation.
B. Set the service binding sendTimeout attribute to 00:00:45.
C. Set the service binding receiveTimeout attribute to 00:00:45.
D. Apply [OperationBehavior (TransaccionScopeRequired=false)] to the service operation.

Question 4

You are developing a Windows Communication Foundation (WCF) service. Client applications require reliable sessions to access the service. Users report that they receive
ServerTooBusyException errors when their client application tries to establish a session. You need to ensure that the service can handle a minimum of 30 client connection requests.
Which ReliableSessionBindingElement property should you configure?

A. MaxRetryCount
B. MaxTransferWindowSize
C. InactivityTimeout
D. MaxPendingChannels

Question 5

You are modifying a Windows Communication Foundation (WCF) service that issues security tokens. The service is accessible through the named pipe protocol. No endpoints are added in the service code. The configuration file for the service is as follows. (Line numbers are included for reference only.)

You need to ensure that new and existing client applications can access the service through HTTP and named pipes.
What should you do?

A. Insert the following line at line 05.
<endpoint address=http://www.contoso.com binding="basicHttpBinding" contract="Contoso.TokenService" />
B. Insert the following line at line 05. <endpoint address=http://www.contoso.com binding="wsHttpBinding" contract="Contoso.TokenService" />
C. Insert the following line at line 08. <add baseAddress="net.tcp://www.contoso.com:8090" />
D. Insert the following line at line 08. <add baseAddress="http://www.contoso.com" />
