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

1. An existing Windows Communication Foundation (WCF) service uses basicHttpBinding. You are releasing updates to the service and the client application.
You need to enable the client application to flow transactions to the service.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A) Change the binding to use wsHttpBinding.
B) Change the binding to use basicHttpContextBinding.
C) Change to a custom binding that has the httpTransport, textMessageEndcoding, and transactionFlow binding elements in this order.
D) Change to a custom binding that has the transactionFlow, textMessageEncoding, and httpTransport binding elements in this order.

2. DRAG DROP
You develop a Windows Communication Foundation (WCF) service that uses the SOAP protocol.
You must secure the service by using Kerberos authentication for the transport layer. The SOAP messages must be authenticated by using a Security Assertion Markup Language (SAML) token.
You need to configure the service configuration file.
How should you complete the relevant markup? (To answer, drag the appropriate markup segment to the correct locations in the answer area. Each markup segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

3. You have a Windows Communication Foundation (WCF) service.
The service has issues with performance when it receives messages on a specific endpoint. The service must collect the minimum number of performance counters to diagnose the message issues.
You need to configure the service.
In the web.config file for the service, what should you do?

A) Enable message logging for the endpoint.
B) In the service configuration diagnostics section, set the value of the performanceCounters property to ServiceOnly.
C) Enable the Windows Management Instrumentation (WMI) provider.
D) In the service configuration diagnostics section, set the value of the performancCounters property to All.

4. A Windows Communication Foundation (WCF) client and service share the following service contract interface.
[ServiceContract]
public interface IContosoService {
[OperationContract]
void SavePerson(Person person);
}
They also use the following binding.
NetTcpBinding binding new NetTcpBinding { TransactionFlow = true };
The client calls the service with the following code
using (TransactionScope ts = new TransactionScope(TransactionScopeOption.Required))
{ IContosoService client = factoryCreateChannelO;
client SavePerson(person);
ConsoleWriteLine(
TransactionCurrentTransactionlnformation.
Distributedldentifier);
tsCompleteO;
}
The service has the following implementation for SavePerson
public void IContosoService SavePerson(Person person)
{ person.Saveo;
ConsoleWriteLine(TransactionCurrentTransactionlnformation.
Distributedidentifier);
}
The distributed identifiers do not match on the client and the server
You need to ensure that the client and server enlist in the same distributed transaction
What should you do?

A) Add the following attributes to the SavePerson operation on lContosoService
[TransactionFlow(TransactionFlowOption Mandatory)]
[OperationBehavior(TransactionScopeRequired true)]
B) Add the following attributes to the SavePerson operation on IContosoService.
[OperationBehavior(TransactionScopeRequired = true)]
[TransactionFlow(TransactionFlowOption.
Mandatory)]
C) Add the following attribute to the SavePerson operation on lContosoSernce [OperationBehavior(TransactionScopeRequired true)] Md the following attribute to the implementation of SavePerson. ITransactionFlow(TransactionFlowOptionAllowed)]
D) Add the following attribute to the SavePerson operation on lContosoService [TransactionFlow(TransactionFlowOption Allowed)] Add the following attribute to the implementation of SavePerson. [OperationBehavior(TransactionScopeRequired true)]

5. A self-hosted Windows Communication Foundation (WCF) service uses a secure HTTP
binding with a custom principal permission mode. The binding requires users to provide their Windows logon credentials.
You need to retrieve the identity of the caller.
What are two possible properties you can use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
