Microsoft 070-503 real exam prep : TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
The service contains the following code segment
[ServiceContract]
public interface IMyService
{
[OperationContract(IsOneWay=true, ProtectionLevel=ProtectionLevel.None)]
[TransactionFlow(TransactionFlowOption.Allowed)]
void DoSomething();
}
You need to ensure that the DoSomething operation can participate in transactions.
Which code segment should you use to replace the existing operation contract?

• A. [OperationContract(ProtectionLevel= ProtectionLevel.EncryptAndSign)]
  [TransactionFlow(TransactionFlowOption.NotAllowed)]
  void DoSomething();
• B. [OperationContract(ProtectionLevel=ProtectionLevel.None)]
  [TransactionFlow(TransactionFlowOption.Allowed)]
  void DoSomething();
• C. [OperationContract(IsOneWay=true, ProtectionLevel=ProtectionLevel.Sign)]
  [TransactionFlow(TransactionFlowOption.Mandatorv)]
  void DoSomething();
• D. [OperationContract(IsOneWay=true,
  ProtectionLevel=ProtectionLevel.EncryptAndSign)]
  [TransactionFlow(TransactionFlowOption.Allowed)]
  void DoSomething();

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application consists of the following components:
An ASP.NET Web application that is deployed on a Web server named WEB1 An ASMX Web service that is deployed on an application server named APP1 A Microsoft SQL Server database that is deployed on a database server named SQL1 The ASP.NET application connects to an ASMX Web service. The APP1 server hosts several ASMX Web service applications. The ASMX Web service stores and retrieves data from SQL1.
You need to ensure that the secure communication strategy meets the following requirements:
The communication configuration between WEB1 and APP1 must be secured without other applications being affected. Server authentication and data encryption must be performed between APP1 and SQL1. Which two secure communication protocols should you use? (Each correct answer presents part of the solution. Choose two.)

• A. Use Internet Protocol Security between APP1 and SQL1.
• B. Use Secure Sockets Layer between APP1 and SQL1.
• C. Use Remote Procedure Call encryption between WEB1 and APP1.
• D. Use Internet Protocol Security between WEB1 and APP1.
• E. Use Remote Procedure Call encryption between APP1 and SQL1.
• F. Use Secure Sockets Layer between WEB1 and APP1.

You create a service by using Microsoft .NET Framework 3.5. You use Windows
Communication Foundation to create the service.
You use the WSHttpBinding binding to prevent tampering of the data. Users report that the
data is unreadable.
You need to troubleshoot the problem by logging the incoming messages. Which code fragment should you use?

• A. Option B
• B. Option D
• C. Option C
• D. Option A

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service is hosted in a managed application.
You need to perform the following tasks:
Publish the service on the following address: net.tcp://localhost:8080/ExamService
Publish the metadata on the following address:
http://localhost:8081/ExamService/metadata?wsdl
Which code fragment should you use?

• A. Option B
• B. Option D
• C. Option C
• D. Option A

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You create the following service definition.
<ServiceContractQ> _ Public Interface IMyService ... End Interface
You need to custom manage the lifetime of the session.
Which service implementation should you use?

• A. <ServiceBehavior(AutomaticSessionShutdown:=False)> _
  Public Class Servicelmp1
  ...
  End Class
• B. <ServiceBehavior(UseSynchronizationContext:=False)> _
  Public Class ServicelmpID
  ...
  End Class
• C. <ServiceBehavior(UseSynchronizationContext:=True)> _
  Public Class Servicelmp1
  ...
  End Class
• D. <ServiceBehavior(AutomaticSessionShutdown:=True)> _
  Public Class Servicelmp1
  ...
  End Class
