MCTS - Microsoft Certified Technology Specialist ASP.NET Web Applications Questions and Answers 1 — Questions and Answers
Question 1: A developer needs to ensure a consistent layout, including a header, footer, and navigation menu, across all pages of a large and complex ASP.NET web application. Which of the following is the most appropriate tool for this requirement?
- User Controls (.ascx)
- Master Pages (.master) (Correct answer)
- Web Forms (.aspx)
- Style Sheets (.css)
Correct answer: Master Pages (.master)
Master Pages are specifically designed to create a consistent look and feel for all pages within an application. A single master page defines the common layout and standard behavior, while individual content pages provide the specific content. User controls are for reusable components within a page, not for overall page layout.
Question 2: In the ASP.NET Page Life Cycle, during which event are control properties loaded with information recovered from view state and control state if the request is a postback?
- PreInit
- Init
- Load (Correct answer)
- PreRender
Correct answer: Load
The 'Load' event is the stage where, if the request is a postback, control properties are populated with data from the view state and control state. In the 'PreInit' and 'Init' stages, this information has not yet been restored. The 'PreRender' event occurs after loading and is used for making final changes before rendering.
Question 3: A developer is implementing a registration form and needs to ensure that the user-entered password and confirmation password fields match. Which validation control is best suited for this task?
- RequiredFieldValidator
- RangeValidator
- RegularExpressionValidator
- CompareValidator (Correct answer)
Correct answer: CompareValidator
The CompareValidator is used to compare the value of one input control to the value of another input control or a fixed value. In this scenario, it would be configured to compare the password and confirmation password fields for equality. The other validators serve different purposes: RequiredFieldValidator ensures a field is not empty, RangeValidator checks if a value is within a range, and RegularExpressionValidator matches against a pattern.
Question 4: You are building a secure section of a website. After a user successfully logs in, you need to determine if they have the permission to access a specific administrative page. What is this process of determining permissions called?
- Authentication
- Authorization (Correct answer)
- Impersonation
- Validation
Correct answer: Authorization
Authorization is the process of determining whether an authenticated user has the necessary permissions to access a specific resource or perform an action. Authentication is the process of verifying the user's identity (e.g., checking their username and password). Authentication always happens before authorization.
Question 5: Which of the following server-side state management techniques stores data that is specific to a single user's session and is maintained on the server?
- View State
- Application State
- Session State (Correct answer)
- Cookies
Correct answer: Session State
Session State is a server-side technique used to store data for a specific user across multiple requests during their session. Application State is also server-side but is global to all users. View State and Cookies are client-side state management options.
Question 6: A developer needs to dynamically create several controls on a page during a postback. To ensure that these controls are correctly added to the page hierarchy and that their view state is properly restored, in which page life cycle event should the controls be created?
- Load
- PreRender
- PreInit (Correct answer)
- InitComplete
Correct answer: PreInit
The PreInit stage is the correct place to create or re-create dynamic controls. Creating them at this stage ensures they are part of the page life cycle early enough for events to be wired up and for view state to be loaded correctly in later stages. If you create them later, such as in the Load event, you may have issues with view state not being applied correctly.
