You've created a new ASP.NET Core application with user registration. Now, you want to ensure that only registered users can post comments. Which attribute would you use to implement this restriction?

  • [AllowAnonymous]
  • [Authorize]
  • [Authorize(Roles = "Admin")]
  • [Authorize(Roles = "User")]
To restrict access to registered users only, you would use the [Authorize] attribute. This attribute can be applied at the controller or action level and ensures that only authenticated users can access the specified resources. It doesn't require specifying roles, as it already implies authenticated users. [AllowAnonymous] would allow both anonymous and registered users, while [Authorize(Roles = "Admin")] and [Authorize(Roles = "User")] are role-based authorizations and are not suitable for this scenario.

You've been reading about the MVC architecture and are trying to understand the components. If you wanted to add logic to fetch data from a database when a user visits a certain page, which component of MVC would handle this?

  • Model
  • View
  • Controller
  • Middleware
In the MVC (Model-View-Controller) architecture, the 'Model' component handles data-related logic, such as fetching data from a database. It represents the application's data and business logic. The 'Controller' handles user input and coordinates the flow of data between the 'Model' and 'View' components.

You are developing an e-commerce site where user's cart information needs to be preserved across sessions even if they log out. How can you achieve this in ASP.NET Core?

  • Use browser cookies to store cart data
  • Utilize Session state with server-side storage
  • Store cart data in a client-side cookie
  • Use local storage in JavaScript
To preserve the user's cart information across sessions, even after they log out, you should utilize Session state with server-side storage. This allows the cart data to be stored on the server, making it persistent across user sessions.

You're trying to locate your application's main CSS files in an ASP.NET Core project. In which directory would you typically find them?

  • wwwroot/css
  • Controllers
  • Models
  • Views
In an ASP.NET Core project, static web assets, such as CSS files, JavaScript files, and images, are typically stored in the "wwwroot" directory. The "wwwroot/css" folder is a common location for CSS files. This separation allows these assets to be served directly to clients without going through the application's routing and controllers.
