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

1. 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 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>
B) 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.
Add the following code segment.
ContosoService client = new ContosoService();
SoapProcessingBehavior behavior = new SoapProcessingBehavior();
behavior.ProcessMessages = true;
client.Endpoint.Behaviors.Add(behavior);
C) In the application configuration file, add the following XML segment to the
system.serviceModel configuration section group.
<diagnostics>
<messageLogging logMessagesAtTransportLevel="true"
logEntireMessage="true" />
</diagnostics>
D) 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));

2. You develop a Windows Communication Foundation (WCF) service.
You name the service MovieService in the Movie namespace. The service is hosted in Microsoft Internet Information Services (IIS).
You copy the assembly containing the service to the bin folder in the virtual directory path.
You need to set up the URI that is mapped to the service.
What should you do?

A) Add a Movie.svc file in the root of the virtual path with the following line.
<%8ServiceHost language="C#" Service="MovieService"*>
B) Add the following code segment to the web.config file.
<serviceHostingEnvironment>
<serviceActivations>
odd relativeAddress="./Movie" service="Movie.MovieService"/>
</serviceAct ivations>
</serviceHostingEnvironment>
C) Add a Movie.svc file in the root of the virtual path with the following line.
<%8ServiceHost language="C#" Service="MovieService.svc"%>
D) Add the following code segment to the web.config file.
<serviceHostingEnvironment>
<serviceActivations>
odd relativeAddress=" . /Movie, svc" service="Hovie.MovieService"/>
</serviceActivations>
</serviceHostingEnvirorunent>

3. You develop an ASP.NET web application that is hosted in the virtual directory named SecureApp. The web application uses the ASP.NET membership provider.
The application pool for the website uses the dedicated domain account named MyDomain\WebServiceAccount. The web.config file contains the connectionStrings element.
You need to secure the connectionStrings element for the web application.
Which of the following two commands must you run at a command prompt? (Each correct answer presents part of the solution. Choose two.)

A) aspnet_regiis -pe "connectionStrings" -app "/SecureApp"
B) aspnet_regsql -pa "NetFrameworkConfigurationKey" "MyDomain\WebServiceAccount"
C) aspnet_regiis -pe "connectionStrings" -app "MyDomain\WebServiceAccount"
D) aspnet_regiis -pa "NetFrameworkConfigurationKey" "MyDomain\WebServiceAccount"

4. A Windows Communication Foundation (WCF) service is responsible for transmitting XML documents between systems.
The service has the following requirements:
- It must minimize the transmission size by attaching the XML document as is without using escape characters or base64 encoding. - It must interoperate with systems that use SOAP but are not built on the .NET platform.
You need to configure the service to support these requirements.
Which message encoding should you use?

A) Text message encoding with message version set to none
B) Binary message encoding
C) Text message encoding with message version set to SOAP 1.2
D) MTOM (Message Transmission Optimization Mechanism) message encoding

5. A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract] public class ContoaServicea { [OperationContract] [TransactionFlow(TransactionFlowOperation. Mandatory)]
[OperationBehavior(TraisactionScopeRequired true,
TransactionAutoCorrolete = false)
void TxOp 1 (string value) { ) [OperationCortract(lsTerminating-true)J
[TransactionFlow(TransactionFlowOption Mandatory)] [OperationBehavior(TraisactionScopeRequired true,
TransationAutoCormplete = false)]
void TxOp2(string value) {.. OperationContext. Current. SetTransactionCompleteO;
)
)
The rvice and the clients that call the service use NetTcpBinding with transaction flow enabled
You need to configure the service so that when TxOpl and TxOp2 are invoked under the same client session, they run under the same transaction context.
What should you do?

A) Update the service contract to read as follows.
(ServiceContract(SessionMode SessionMode Required)J Add the following behavior to the
service implementation
[ServiceBehavior(lnstanceCoritextMode = Instance ContextMode. PerSession)]
B) Update the service contract to read as follows.
[ServiceContract(SessionMode = SessionMode.Required)]Md the following behavior to the
service implementation.
[ServiceBehavior(lnstanceContextMode = lnstanceContextMode. PerCall)]
