You are designing a data validation strategy for an ASP.NET Web application. A page of the
Web application includes multiple Panel controls. Each panel contains input controls,
validator controls, and a Submit button. When a user clicks a Submit button, the Web
application must validate only the values of the input controls on the panel containing that
Submit button. You need to recommend an approach for validating the values. What should
you recommend?

You are designing a data access strategy for an ASP.NET Web application. You plan to
expose an existing data source by using WCF Data Services. You need to recommend an
approach to ensure that CRUD operations are possible. What should you recommend?

You are designing an ASP.NET Web application. Pages of the Web application will share a
common layout. Different business logic will be executed based on user input. You have the
following requirements: • Use view state to maintain data between postbacks. • Reuse
presentation logic across multiple pages. You need to recommend an approach that meets
the requirements. What should you recommend?

You are designing an ASP.NET MVC 2 Web application. When the Web application is
accessed through the . . . /Products/Categories URL, it will display a list of products sorted
by category. You have the following requirements: • The Web application design must be
loosely coupled. • The Web application must support unit testing of the data layer code. You
need to recommend a location for the code that maps and retrieves products from the data
store. Which location should you recommend?

You are designing an ASP.NET MVC 2 Web application. The Web application will display
information from remote third-party Windows Communication Foundation (WCF) services
on each page. You have the following requirements: • Retrieve information from the WCF
services. • Specify a timeout period while retrieving information from third-party services. •
Cache responses from the third-party services for retrieval by multiple users. You need to
recommend an approach for retrieving information from the WCF service. What should you
recommend?

You are designing an ASP.NET MVC 2 Web application. A page of the Web application will
display data retrieved from a Web service. The Web service performance is unpredictable.
You have the following requirements: • Display a progress indicator while retrieving data. •
Display data in the same page from which it is retrieved. You need to recommend a solution
that meets the requirements. What are two possible solutions you could recommend? (Each
answer presents a complete solution. Choose two.)

You are conducting an architectural review of an existing ASP.NET Web application. The
Web application uses only full-page postbacks, which degrades its performance. You have
the following requirements: • Extend existing control by using AJAX functionality. • Reduce
the size of postbacks without modifying the existing controls. You need to recommend an
approach for meeting the requirements. What should you recommend?

You are designing an ASP.NET Web application that will support multiple display
languages. You have the following requirements: • Change server control setting based on

the selected language. • Enable strongly typed access to the resource objects. You need to
recommend a strategy for localizing server control properties. Which strategy should you
recommend?

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?

Vou are designing an ASP.NET Web application. A page of the Web application will use the
ASP.NET Calendar server control. Users will select the type of calendar from a drop-down
list named CalendarType. The CalendarType list contains cultural preferences. You need to
recommend an approach for rendering the calendar control based on the selected cultural
preference. What should you recommend?
