Microsoft Designing & Developing Web Apps Using MS .NET Frmwk 4 Sample Questions:

1. You are designing a testing methodology for an ASP.NET MVC 2 Web application.
The application has a simple domain model that provides a thin wrapper over a data access layer.
Controllers interact with the domain model directly and use methods on repository objects to save and retrieve objects from the data access layer.
You have the following requirements:
You need to design tests against the appropriate layer to meet the requirements.
Which layer should you recommend?

A) the repository objects
B) the data access layer
C) the controllers
D) the domain model

2. You are designing the deployment strategy for an ASP.NET Web application that consists of multiple pages. The Web application will be deployed to a server that hosts multiple ASP.NET applications.
The Web application design includes;
Error pages named LoginErrors.htm and GenericErrorPage.htm.
A subdirectory named Login that contains only the Login.aspx page.
You have the following requirements:
Display the LoginErrors.htm page for all unhandled errors that are generated from the Login.aspx page.
Display the GenericErrorPage.htm page for all other unhandled errors.
You need to recommend an approach for displaying the error pages.
Which two actions should you recommend? (Each correct answer presents part of the solution. Choose two.)

A) Add the following XML element to the Machine.config file in the .NET Framework
installation folder:
<customErrors defaultRedirecta"GenericErrorPage.htm" />
B) Add the following XML element to the Machine.conftg file in the .NET Framework
installation folder:
<customErrors defaultRedirect="LoginErrors.htm" />
C) Add the following XML element to the Web.config file in the root application directory:
<customErrors defaultRedirect="GenericErrorPage.htm" />
D) Add the following XML element to the Web.config file in the Login directory: <
customErrors defaultRedirect="LoginErrors.htm" />

3. You are designing an ASP.NET Web application that targets multiple browsers and form factors.
Some devices do not support the markup produced by a third-party server control. You cannot modify the third-party server control.
You need to recommend an approach for providing the correct markup for the problematic devices.
What should you recommend?

A) Create an ASP.NET theme specific to each problematic device. In the page PreRender event, set the Theme property to the custom theme based on the value of the Request.Browser.Type property.
B) Derive a class from the third-party server control. In the new server control, override the TemplateSourceDirectory property to return a value pointing to a file containing the device-specific markup.
C) In the page PreRender event, call the Response.WriteSubstitution() method with a delegate. In the delegate, populate the page with device-specific markup based on the value of the Request.Browser.Type property.
D) Derive a class from ControlAdapter that produces device-specific markup. In the browser definition file, add an entry in the controlAdapters collection for each of the problematic devices. In the entry, point to the third-party server control and adapter type.

4. You are designing an ASP.NET MVC 2 Web application for a customer's extranet site.
You need to allow only requests that originate from the customers intranet IP address range to access the application, and you must redirect other access requests to the
customers Web site.
Which approach should you recommend?

A) Design the default controller and action to check the IP address and to redirect requests from outside the specified IP address range to the public Web site.
B) Configure the IIS URL Rewrite module to redirect requests from outside the specified IP address range to the public Web site.
C) Configure IIS to reject requests from outside the specified IP address range.
