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

1. A Windows Communication Foundation (WCF) application exposes a service as a SOAP endpoint for consumption by cross-platform clients. During integration testing, you find that one of the clients is not generating the correct messages to the WCF application.
In order to debug the issue and fix the communication, you need to configure the service to log messages received from the client.
What should you do?

A) Set an etwTracking behavior on the service and configure a listener for the System.ServiceModel trace source.
B) Set an etwTracking behavior on the service and configure a listener for the System.ServiceModel.MessageLuqqing trace source.
C) Enable messageLogging in the System.ServiceModel diagnostics element configuration and configure a listener for the System.ServiceModel.MessageLogging trace source.
D) Enable messageLogging in the System.ServiceModel diagnostics element configuration and configure a listener for the System.ServiceModel trace source.

2. You develop a Windows Communication Foundation (WCF) SOAP service that contains a class named Order. The Order class includes a field named secret that stores private data.
The Order class includes the following code:

The service has the following requirements:
- The secret field must be encrypted.
- All other fields in the Order class must serialize as plain text. You need to configure serialization for the Order class.
What should you do?

A) Add a MessageHeader attribute to the secret field and set the ProtectionLevel to
EncryptAndSign.
Add a MessageBodyMember attribute to each of the other fields of the class.
B) Add a MessageBodyMember attribute to the secret field and set the ProtectionLevel to
Sign.
Add a MessageBodyMember attribute to each of the other fields of the class.
C) Add a MessageBodyMember attribute to the secret field and set the ProtectionLevel to
EncryptAndSign.
Add a MessageBodyMember attribute to each of the other fields of the class.
D) Add a MessageHeader attribute to the secret field and set the ProtectionLevel to Sign.
Add a MessageBodyMember attribute to each of the other fields of the class.

3. You are developing a Windows Communication Foundation (WCF) service that contains the following operation contract.
<OperationContract()>
Function GetCustomerNames() As CustomerNames
The operation returns customer names.
You need to develop a definition for the operation contract that produces XML with the following structure.

Which code segment should you use

A) <DataContract()> Public Class CustomerNames <DataMember(IsRequired:=False)> Public Names() As String End Class
B) <MessageBodyMember()> Public Names() As String End Class
C) <DataContract()> Public Class CustomerNames <DataMember ()> Public Names () As String End Class
D) <MessageContract(WrapperName:="")> Public Class CustomerNames
E) <MessageContract(IsWrapped:=False)> Public Class CustomerNames
F) <MessageBodyMember()> Public Names() As String End Class

4. A service implements the following contract. (Line numbers are included for reference only.)

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.
<OperationBehavior(
TransactionScopeRequired:=True,
TransactionAutoComplete:=False)>
Insert the following attribute to OperationTwo on ContosoService.
<OperationBehavior
(TransactionScopeRequired:=True,
TransactionAutoComplete:=True)>
D) Insert the following attribute to OperationOne on IContosoService.
<TransactionFlow(TransactionFlowOption.Mandatory)>
Insert the following attribute to OperationTwo on IContosoService.
<TransactionFlow(TransactionFlowOption.Mandatory)>

5. A Windows Communication Foundation (WCF) service exposes two operations: OpA and OpB OpA needs to execute under the client's identity, and OpB needs to execute under the service's identity.
You need to configure the service to run the operations under the correct identity
What should you do?

A) Set the ImpersonateCallerForAllOperations property of the service's
ServiceAuthorizationBehavior to false.
Apply an OperationBehavior attribute to OpA and set the Impersonation property to
ImpersonationOptionAllowed.
Apply an OperationBehavior attribute to OpB and set the Impersonation property to
ImpersonationOption
NotAllowed
B) Set the ImpersonateCallerForAllOperations property of the service's ServiceAuthorizationBehavior to true. Apply an OperationBehavior attribute to OpA and set the Impersonation property to ImpersonationOption Required Apply an OperationBehavior attribute to OpB and set the Impersonation property to ImpersonationOptionAulowed.
C) Set the ImpersonateCallerForAllOperations property of the service's
ServiceAuthorizationBehavior to false.
Apply an OperationBehavior attribute to OpA and set the Impersonation property to
lmpersonationOption.Required.
Apply an OperationBehavior attribute to OpB and set the Impersonation property to
ImpersonationOption.Allowed.
D) Set the ImpersonateCallerForAllOperations property of the service's
