You are designing an ASP.NET Web Forms application that uses a database containing user names and
hashed passwords for authentication. The Web application includes a login form in which users type their
user names and passwords.
You need to design a strategy to ensure that the user's login credentials cannot be stolen through a man-
in-the-middle attack.
Which approach should you recommend?

You use Microsoft Visual Studio 2010 and Microsoft. NET Framework 4 to create an application. The application connects to a Microsoft SQL Server database. You use Entity SQL of the ADO.NE Entity Framework to retrieve data from the database. You need to define a custom function in the conceptual model. You also need to ensure that the function calculates a value based on properties of the object. Which two XML element types should you use? (Each correct answer presents part of the solution. Choose two.)

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?

Four Windows Communication Foundation (WCF) services are hosted in Microsoft Internet Information
Services (IIS). No behavior configuration exists in the web.config file.
You need to configure the application so that every service and endpoint limits the number of concurrent
calls to 50 and the number of concurrent sessions to 25.
Which XML segment should you add to the system.serviceModel configuration section of the web.config
file?

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?

You use Microsoft Visual Studio 2010 and Microsoft ADO.NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. You use the ADO.NET LINQ to SQL model to retrieve data from the database. You use stored procedures to return multiple result sets. You need to ensure that the result sets are returned as strongly typed values. What should you do?

You are designing an ASP.NET Web application for online image editing. Users can upload images to the
Web application and edit those images by using utilities provided by the application. Some utilities are
processor intensive and should be offloaded to a Graphics Processing Unit (GPU). Other utilities require
the use of proprietary algorithms that must be performed on the server.
You need to design a solution for minimizing bandwidth usage and Web server response times during
image processing, while providing a responsive application.
Which two approaches should you recommend? (Each correct answer presents part of the solution.
Choose two.)

You are designing an ASP.NET Web application for content management.
You have the following requirements:
*Support multiple languages.
*Support dynamic changes to site content.
*Provide the ability to add content to the site without making changes to files within the application directory.
You need to recommend the application's source for retrieving content.
Which source should you recommend?

You are designing a user input form that is part of an ASP.NET Web Forms application. You need to ensure that users cannot attack the Web server by submitting invalid data. Which approach should you recommend?
