What should you do?
You are creating a Windows Communication Foundation (WCF) service based on WSHttpBinding. New audit requirements dictate that callers must be authenticated on every call to ensure that their credentials have not been revoked.
You need to ensure that the service will not cache the security request token.
What should you do?
What should you do?
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to model entities. The application allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements: Changes made to the local data store in disconnected mode are preserved. Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data. What should you do?
What should you do?
You are developing an ASP.NET Web application.
Application data is stored in a Microsoft SQL Server 2008 database.
You configure a connection string named cnnContoso.
The application must cache the data that is returned from the database by using this connection string.
You need to ensure that the application checks the database every 10 seconds.

Which code segment should you use?
You are consuming a Windows Communication Foundation (WCF) service in an ASP.NET Web application. The service interface is defined as follows.
[ServiceContract]
public interface ICatalog
{
[OperationContract]
[WebGet(UriTemplate = “/Catalog/Items/{id}”,
ResponseFormat = WebMessageFormat.Json)]
string RetrieveItemDescription(int id);
}
The service is hosted at /Catalog.svc.
You need to call the service using jQuery to retrieve the description of an item as indicated by a variable named itemId.
Which code segment should you use?
What should you do?
You use Microsoft .NET Framework 4 to create a Windows Presentation Foundation (WPF) application named MyApp.exe. You use Microsoft Windows Installer to package the application. You create an icon file named Application.ico. You need to associate Application.ico with MyApp.exe when MyApp.exe is deployed. What should you do?
Which two actions should you perform?
You are developing an ASP.NET Web service.
The following code segment implements the service. (Line numbers are included for reference only.)
01 [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
02 public class ProductService : System.Web.Services.WebService
03 {
04 [WebMethod]
05 public Product GetProduct(string name)
06 {
07
08 }
09
10 [WebMethod]
11 public Product GetProduct(int id)
12 {
13
14 }
15 }
You need to ensure that both GetProduct methods can be called from a Web client.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
What should you do?
A Windows Communication Foundation (WCF) service has a callback contract.
You are developing a client application that will call this service.
You must ensure that the client application can interact with the WCF service.
What should you do?
Which testing strategy should you recommend?
You are developing a Windows Presentation Foundation (WPF) application by using Microsoft .NET Framework 4. You need to recommend a testing strategy to identify the additional hardware resources that are necessary to support future projected growth. Which testing strategy should you recommend?
Which method of the FieldTemplateUserControl class should you override in the BooleanField class?
You are developing an ASP.NET Dynamic Data Web application.
Boolean fields must display as Yes or No instead of as a check box.
You replace the markup in the default Boolean field template with the following markup.
<asp:Label runat=”server” ID=”label” />
You need to implement the code that displays Yes or No.
Which method of the FieldTemplateUserControl class should you override in the BooleanField class?
Which class should you use?
You are building a client for a Windows Communication Foundation (WCF) service.
You need to create a proxy to consume this service.
Which class should you use?
