You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application uses DataContexts to query the database. You create a function that meets the following requirements: "Updates the Customer table on the database when a customer is marked as deleted. "Updates the related entries in other tables (CustomerAddress, CustomerContacts) by marking them as deleted. "Prevents consumer code from setting the Deleted column's value directly. You need to ensure that the function verifies that customers have no outstanding orders before they are marked as deleted. You also need to ensure that existing applications can use the update function without requiring changes in the code. What should you do?

• A. Override the Delete operation of the DataContext object.
• B. Modify the SELECT SQL statement provided to the DataContext object to use an INNER JOIN between the Customer and Orders tables.
• C. Add new entities to the DataContext object for the Customers and Orders tables.
• D. Override the Update operation of the DataContext object.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use Microsoft ADO.NET Entity Data Model (EDM) to model entities. You create an entity named Person with a schema defined by the following XML fragment.
<EntityType Name="CPerson">
<Key>
<PropertyRef Name="PersonId" />
</Key>
<Property Name="PersonId" Type="Int32" Nullable="false" />
<Property Name="CompanyName" Type="String" />
<Property Name="ContactName" Type="String" />
<Property Name="ContactTitle" Type="String" />
<Property Name="Address" Type="String" /> </EntityType>
You need to ensure that entities within the application are able to add properties related to the city, region, and country of Person's address. What should you do?

• A. "Create a new complex type named CAddress that contains the properties for city, region, and country. "Change the Type of the Address property in CPerson to "Self.CAddress".
• B. "Create a SubEntity named Address. "Map the SubEntity to a stored procedure that retrieves city, region, and country.
• C. "Create a new entity named Address. "Add a person ID property to filter the results to display only the City, Region, and Country properties for a specific Person entity.
• D. "Create a view named Name that returns city, region, and country along with person IDs. "Add a WHERE clause to filter the results to display only the City, Region and Country properties for a specific Person entity.

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.)

• A. Perform server-side image processing on the Web server.
• B. Perform server-side image processing on a dedicated server.
• C. Perform client-side image processing by using ASP.NET AJAX.
• D. Perform client-side image processing by using Microsoft Silverlight.

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. You need to create a database from your model. What should you do?

• A. Use the Update Model Wizard in Visual Studio.
• B. Use the Generate Database Wizard in Visual Studio. Run the resulting script against a Microsoft SQL Server database.
• C. Run the edmgen.exe tool in FromSSDLGeneration mode.
• D. Run the edmgen.exe tool in FullGeneration mode.

You are implementing an ASP.NET application that makes extensive use of JavaScript libraries. Not all pages use all scripts, and some scripts depend on other scripts. When these libraries load sequentially, some of your pages load too slowly. You need to use the ASP.NET Ajax Library Script Loader to load these scripts in parallel. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.
• B. In each page that uses scripts, add a call to Sys.get for each script that is needed in that page.
• C. In your site's master page, add a call to Sys.loader.registerScript to define each of the scripts that are used in the site.
• D. In your site's master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.
