Mvc Interview Questions And Answers

1. Purpose of the Model in MVC:

Ans.

• The Model in the MVC (Model-View-Controller) pattern represents the application’s data and business logic.
• It is responsible for managing data, processing business rules, and interacting with the database.

2.Role of the View in MVC:

Ans.

• The View is responsible for presenting data to the user and handling user interface interactions.
• It displays information from the Model and sends user input back to the Controller for processing.

3.Role of the Controller in MVC:

Ans.

• The Controller manages user input, processes it (along with data from the Model), and updates the View accordingly.
• It acts as an intermediary between the Model and the View, handling user requests and updating the application state.

4.Advantages of Using the MVC Pattern:

Ans.

• Separation of Concerns: Clear separation of application logic, user interface, and data management.
• Modularity: Components (Model, View, Controller) can be developed and tested independently.
• Reusability: Components can be reused in different parts of the application.
• Maintainability: Easier maintenance and updates due to the modular and organized structure.

5.Flow of Data in MVC:

Ans.

• User interacts with the View.
• View sends user input to the Controller.
• Controller processes input, interacts with the Model, and updates the View.
• View displays updated data to the user.
• This cycle continues based on user interactions.

6.Differences Between ASP.NET Web Forms and ASP.NET MVC:

Ans.

• Web Forms: Event-driven, controls with server-side state, less control over HTML, follows a page-centric approach.
• MVC: Separation of concerns, full control over HTML, supports test-driven development, follows an action-centric approach.

7.Data Flow Between View and Controller in MVC:

Ans.

• User interacts with the View (e.g., form submission).
• View sends data to the Controller.
• Controller processes data, updates the Model if needed, and returns a response.
• View displays the updated information to the user.

8.Purpose of ViewBag in MVC:

Ans.

• ViewBag is a dynamic property that allows passing data from the Controller to the View.
• It is useful for sending small amounts of data between the Controller and the View without using strongly-typed models.

9.Handling Form Submissions in MVC:

Ans.

• Create a form in the View with appropriate HTML helpers.
• Submit the form to an action method in the Controller.
• Controller processes form data, performs necessary actions, and updates the Model or View.
• Use model binding to simplify handling form data in the Controller.

10.Purpose of Routing in MVC:

Ans.

• Routing is the process of mapping URLs to Controller actions.
• It helps determine which Controller and action should handle a particular URL request.
• Enables creating clean and user-friendly URLs for different parts of the application.
