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

Question #1

A Windows Communication Foundation (WCF) service interacts with the database of a workflow engine. Data access authorization is managed by the database, which raises security exceptions if a user is unauthorized to access it.
You need to ensure that the application transmits the exceptions raised by the database to the client that is calling the service.
Which behavior should you configure and apply to the service?

A. workflowUnhandledException
B. serviceDebug
C. routing
D. serviceSecurityAudit

Question #2

Your Windows Communication Foundation (WCF) client application uses HTTP to communicate with the service.
You need to enable message logging and include all security information such as tokens and nonces in logged messages.
What should you do?

A. In the application configuration file, add the following XML segment to the
system.serviceModel configuration section group.
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"
logEntireMessage="true" />
</diagnostics>
B. In the machine configuration file, add the following XML segment to the
system.serviceModel configuration section.
<machineSettings enableLoggingKnownPii="true" />
In the application configuration file, add the logKnownPii attribute to the message logging
diagnostics source and set the value of the attribute to true. In the application configuration
file, add the following XML segment to the system.serviceModel configuration section
group.
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"/>
</diagnostics>
C. In the machine configuration file, add the following XML segment to the
system.serviceModel configuration section.
<machineSettings enableLoggingKnownPii="true" />
Generate the ContosoService class using the Add Service Reference wizard.
Add the following code segment.
ContosoService client = new ContosoService();
client.Endpoint.Behaviors.Add(new CallbackDebugBehavior(true));
D. In the application configuration file, add the logKnownPii attribute to the message
logging diagnostics source and set the value of the attribute to true.
Generate the ContosoService class using the Add Service Reference wizard. Add a
reference to System.ServiceModel.Routing.dll.

The service is implemented as follows.

ContosoService uses NetMsmqBinding to listen for messages. The queue was set up to use transactions for adding and removing messages.
You need to ensure that OperationOne and OperationTwo execute under the same transaction context when they are invoked in the same session.
What should you do?

A. Add the following XML segment to the application config file in the
system.serviceModel/bindings configuration section.
<customBinding>
<binding name="contosoTx">
<transactionFlow />
<binaryMessageEncoding />
<msmqTransport durable="true" />
</binding>
</customBinding>
Then use the CustomBinding named contosoTx to listen for messages from the clients.
B. Add the following XML segment to the application config file in the
system.serviceModel/bindings configuration section.
<netMsmqBinding>
<binding name="contosoTx" durable="true" receiveContextEnabled="true" />
</netMsmqBinding>
Then use the NetMsmqBinding named contosoTx to listen for messages from the clients.
C. Insert the following attribute to OperationOne on ContosoService.
