Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. 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?

A) Call the query's Execute method by using the MergeOptions.AppendOnly option.
B) Call the query's Execute method by using the MergeOptions.OverwriteChanges option.
C) Call the Refresh method of ObjectContext by using the RefreshMode.StoreWins option.
D) Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.

2. You are implementing an ASP.NET Dynamic Data Web site.
The Web site includes a data context that enables automatic scaffolding for all tables in the data model.
The Global.asax.cs file contains the following code segment. public static void RegisterRoutes
(RouteCollection routes) { {
routes.Add(new DynamicDataRoute("{table}/ListDetails.aspx") {
Action = PageAction.List,
ViewName = "ListDetails",
Model = DefaultModel
});
routes.Add(new DynamicDataRoute("{table}/ListDetails.aspx") {
Action = PageAction.Details,
ViewName = "ListDetails",
Model = DefaultModel
});
}
You need to display the items in a table named Products by using a custom layout.
What should you do?

A) Add a new Web page named Products.aspx to the Dynamic Data\PageTemplates folder of the Web site.
B) Add a new Web user control named Products.ascx to the Dynamic Data\Filters folder of the Web site.
In the code-behind file for the control, change the base class from UserControl to System.Web.
DynamicData.QueryableFilterUserControl.
C) Add a new folder named Products to the Dynamic Data\CustomPages folder of the Web site. Add a new Web page named ListDetails.aspx to the Products folder.
D) Add a new Web user control named Products_ListDetails.ascx to the Dynamic Data\EntityTemplates folder of the Web site. In the code-behind file for the control, change the base class from UserControl to System.Web. DynamicData.EntityTemplateUserControl.

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use the ADO.NET Entity Data Model (EDM) to define a Customer entity. You need to add a new Customer to the data store without setting all the customer's properties. What should you do?

A) Override the Create method for the Customer object.
B) Call the Create method of the Customer object.
C) Override the SaveChanges method for the Customer object.
D) Call the CreateObject method of the Customer object.

4. You are designing an ASP.NET Web application.
You have the following requirements:
*Users must be allowed to save their work in progress on one computer and to continue the work on
another computer.
*Data that is submitted for processing must be valid, and invalid data must be rejected.
*Primary key constraints within the database must be enabled at all times.
*The application must store only data that is entered by the user.
You need to design data validation to support the requirements.
Which two approaches should you recommend? (Each correct answer presents part of the solution.
Choose two.)

A) Use validators to verify the data when the user submits a form.
B) Provide default values for the database columns, and submit the form with user-entered values when the user saves the form.
C) Store temporary form data as XML in a database table.
D) Add an isTemporary column to each database table, and set all columns to allow null values.

5. You need to design a solution for capturing an exception. Which approach should you recommend?

A) Use a customErrors element.
B) Use a Page_Error method.
C) Use an Application_Error method.
D) Use a HandleError attribute.
