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. You use
the ADO.NET Entity Framework to model your entities.
You use Plain Old CLR Objects (POCO) entities along with snapshot-based change tracking. The code
accesses the POCO entities directly.
You need to ensure that the state manager synchronizes when changes are made to the object graph.
Which ObjectContext method should you call?

A) ApplyPropertyChanges
B) SaveChanges
C) DetectChanges
D) Refresh

2. You have an ASP.NET Web Forms application for processing orders.
Many users of the application submit their order forms multiple times due to incorrectly formatted credit
card information.
You need to plan for validation of the length and format of data in the credit card field on the client side prior
to processing each transaction.
Which approach should you recommend?

A) Use a CustomValidator control in the OnServerValidate method.
B) Use a RequiredFieldValidator control and a RegularExpressionValidator control.
C) Use a CustomValidator control in the Page_Load method.
D) Use a RequiredFieldValidator control and a CompareValidator control.

3. 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 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.
B) Add a new Web page named Products.aspx to the Dynamic Data\PageTemplates folder of the Web site.
C) 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.
D) 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.

4. You are implementing an ASP.NET page in an e-commerce application. Code in a btnAddToCart_Click
event handler adds a product to the shopping cart.
The page should check the status of the shopping cart and always show a cart icon when one or more
items are in the shopping cart. The page should hide the icon when the shopping cart has no items. You
need to add an event handler to implement this requirement.
Which event handler should you add?

A) btnAddToCart_Click
B) Page_PreRender
C) Page_Load
D) Page_PreInit

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to several SQL Server databases. You create a function that modifies customer records that are stored in multiple databases. All updates for a given record are performed in a single transaction. You need to ensure that all transactions can be recovered. What should you do?

A) Call the Reenlist method of the TransactionManager class.
B) Call the EnlistVolatile method of the Transaction class.
C) Call the RecoveryComplete method of the TransactionManager class.
D) Call the EnlistDurable method of the Transaction class.
