Microsoft TS Microsoft .NET Framework 3.5 Windows Communication Foundation Set 4

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service. The service will be consumed by a client-side code that runs in the Web pages of an ASP.NET AJAX Web application. You need to ensure that data serialization between the service and the application incurs minimum latency. Which data format should you use?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application processes sales order documents. The application contains a component that retrieves the sales order documents from a FTP server and stores the data in a Microsoft SQL Server database. You need to ensure that the component meets the following requirements: Periodically polls the FTP server to check for new order documents Executes without dependencies on other software components Executes without user interaction Executes by using a specific security context Allows system administrators to change the security context by retaining the same component code What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. You configure the Windows Communication Foundation (WCF) service to be exposed by using the HTTP and TCP endpoints. You plan to deploy the WCF service. You need to identify the host environment that provides the following services: Message-based activation Health management Process recycling capabilities Which hosting environment should you use?

You are creating an application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application. The YourUserNamePasswordValidator class is implemented in the host application of the WCF service. The host application is named YourServiceHost.exe. You write the following code segment. namespace YourSecureService { class YourUserNamePasswordValidator : UserNamePasswordValidator { public override void Validate(string userName, string password) { ... }} } You need to perform custom validation of the user name and password by using the YourUserNamePasswordValidator class. What should you do?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.) 01 Uri baseAddress= 02 new Uri (?http://localhost:8000/ExamService?); 03 Uri mexAddress=new Uri(""); 04 ServiceHost serviceHost=new ServiceHost(typeof( 05 ExamService), baseAddress); 06 ServiceMetadataBehavior smb= 07 serviceHost.Description.Behaviors. 08 Find(); 09 if (smb != null) 10 { 12 } 13 else 14 { 15 smb=new ServiceMetadataBehavior(); 16 serviceHost.Description.Behaviors.Add(smb); 17 } 18 smb.HttpGetUrl=mexAddress; When you browse to the base address of the service, you receive the following message: "Metadata publishing for this service is currently disabled." You debug the code and discover that the ServiceMetadataBehavior behavior was previously nonexistent. You need to enable metadata publishing. What should you do?

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The service will be hosted on a Web server. You plan to deploy the service in an existing Web application. You need to identify the Web applications on the Web server that are registered for WCF. Which utility should you use?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract. (Line numbers are included for reference only.) 01 [ServiceContract] 02 public interface IMyService 03 { 04 [OperationContract] 06 List GetData(int index); 07 } You need to ensure that the GetData operation can be accessed by using the URI in the following manner: GetData/1 for the index value 1 GetData/2 for the index value 2 .. GetData/n for the index value n Which code segment should you insert at line 05?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service has an operation contract named GetMessage. You write the following code segment to implement the service. (Line numbers are included for reference only.) 01 public Message GetMessage() 02 { 03 Message msg=null; 04 string action="GetMessageResponse"; 05 MessageVersion ver=MessageVersion.Default; 06 FileStream stream=new FileStream(@"D:\File.xml", 07 FileMode.OpenOrCreate); 09 return msg; 10 } You need to send the contents of the File.xml file to a client application by using the SOAP body. Which code segment should you insert at line 08?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The component will return custom business objects. You plan to develop a design strategy that meets the following requirements: The component can be accessed by the .NET Windows applications and JavaScript- based Web applications. The component can be consumed by the client applications by using the minimum amount of code. The least amount of network bandwidth is consumed. You need to implement the design strategy by using the minimum amount of development effort. What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service that will be consumed by an ASP.NET application. The WCF application and the ASP.NET application will be deployed on the same server. You need to ensure that the WCF service meets the following requirements: The communication between the applications incurs minimum latency. The binding satisfies the ordered delivery constraint that is specified in the service implementation by using the DeliveryRequirements attribute. Which binding object should you use?
