Frequently asked MVC Interview Questions and Answers

Here are some asp.net MVC interview questions that will help freshers and experienced candidates get an edge while searching for their preferred role.

1. Explain MVC in Brief

The Model-View-Controller is a framework for building web applications. A model can be defined as the data used by the application program. It handles the logic for application data and has a database to store and retrieve data.

The view is a part that handles the display of the data, usually the user interface within the application. End users communicate with this part of the application.

The controller is responsible for updating models and views according to user actions. It accepts the input from the user, sends it to the respective controller within the model, and chooses to show a view that displays the user interface.

2. Explain some benefits of using MVC

The key benefits of MVC include:

• Supporting Multiple Views
  The user interface can display multiple views of the same data concurrently. It is possible because of the separation of the model from its view.
•  More Control
  The ASP.NET MVC framework offers greater control over the latest web forms like HTML and Javascript.
•  Lightweight
  Since this framework doesn’t use a View state, it minimizes the requested bandwidth to a certain extent while running the web application.
•  Faster Development Process
  The ASP.NET core MVC framework supports parallel development. It implies that two bprogrammers can perform some action in different layers of the application at the same time without causing any interference with each other’s actions. It leads to the rapid development of the application.
•  Simple To Manage
  The web application developed using the MVC framework is easy to manage and maintain while in its progressive stages.

3. How to maintain the sessions in MVC?

There are 3 ways to maintain the sessions in an MVC framework. It is listed below:

• View data
  It is used for maintaining the data when you shift from a controller to a view within an application.
• Temp data
  It is used to maintain the data when there is a shift of action from one controller to another.
• View bag
  It acts as the dynamic wrapper for the data in the view section.

4. How to execute an MVC Project?

Follow these steps to execute an MVC project:

• Accept the first request for application.
• Perform the Routing.
• An MVC Request Handler is created.
• Post that, the controller is created and executed.
• The particular action is invoked.
• Finally, the results are executed.

5. What do you mean by Routing in MVC?

MVC Routing is the pattern-matching scheme used for mapping incoming requests of web browsers to a specific controller action.

6. How will you navigate from one view to another in MVC?

You can use the action link method to navigate from one view to another. A code is used to create a simple URL that helps to navigate to the ‘Home’ controller and invoke the Gotohome action.

7. Define Output Caching in MVC?

Output Caching is an approach that improves the performance of an MVC application. It enables the users to cache the data sent back by the controller method. It prevents the earlier data from getting regenerated each time while invoking the same controller method. It reduces the database server round trips and reduces network traffic.

8. Give two examples where Routing cannot be used or isn’t necessary to be used?

The two situations where routing is not necessary include:

• In an instance where there is a physical file matching the URL pattern.
• When any routing gets disabled in any particular URL form.

9. How is View different from Partial View?

A view contains the layout page, whereas a partial view does not contain the layout page. A viewstart page is rendered first before rendering any new view. In contrast, a partial view does not verify the viewstart page. Therefore, the partial view is more lightweight compared to the view page.

10. What are the important points to remember while creating an MVC Application?

There are two important factors to remember while creating an MVC application.

• The approach of MVC application development should be decided on the application requirements and features to suit the specific development needs.
• Always aim for high application maintainability with the separation of application tasks.
