Servlets in an MVC framework typically receive user input through __________.

  • cookies
  • hidden fields
  • request parameters
  • session attributes
Servlets in an MVC framework typically receive user input through request parameters, which are data sent by the client as part of the HTTP request and can be accessed by the servlet.

The __________ pattern used in MVC frameworks centralizes request handling in a single servlet.

  • Adapter
  • Front Controller
  • Observer
  • Strategy
The Front Controller pattern used in MVC frameworks centralizes request handling in a single servlet.

Which component in the MVC framework is typically implemented using servlets?

  • Controller
  • DAO
  • Model
  • View
In the MVC framework, servlets are typically used to implement the Controller component, responsible for handling user input, processing requests, and interacting with the model and view components.

In an MVC-based web application, where do servlets generally fit in?

  • Controller
  • DAO
  • Model
  • View
In an MVC-based web application, servlets generally fit in the Controller layer. They handle user input, process requests, and coordinate communication between the model and view components.

How are requests forwarded from servlets to the appropriate view in an MVC framework?

  • Forward
  • Include
  • Redirect
  • Response.sendRedirect()
Requests from servlets to the appropriate view in an MVC framework are forwarded using the Forward mechanism, allowing seamless interaction between the controller and the view components.

To maintain a separation of concerns, servlets in MVC should not directly manipulate the __________.

  • Controller
  • Database
  • Model
  • View
To maintain a separation of concerns, servlets in MVC should not directly manipulate the Controller.

The __________ method in servlets is often used to dispatch requests to different handlers in an MVC framework.

  • doDispatch()
  • doPost()
  • init()
  • service()
The doDispatch() method in servlets is often used to dispatch requests to different handlers in an MVC framework.

In a complex web application using MVC and servlets, a new feature requires integration of a third-party service. Where should this integration primarily take place?

  • In a separate utility class
  • In the Controller
  • In the Model
  • In the View
In MVC architecture, business logic, including third-party service integration, is primarily handled in the Controller. This ensures separation of concerns and makes the application more modular.

A web application needs to redirect the user to different pages based on their role. How should this logic be implemented using servlets in MVC?

  • In the Controller
  • In the Model
  • In the View
  • Using servlet filters
The logic for redirecting users based on their role should be implemented in the Controller. The Controller handles the application's flow and decides which view to render based on the user's role.

A servlet is configured with specific initialization parameters. How does this impact the servlet's processing of requests?

  • The parameters are accessible using the getInitParameter() method within the servlet.
  • The parameters are accessible using the request.getParameter() method.
  • The parameters are automatically injected into the servlet methods.
  • The parameters are only accessible in the doPost() method.
When a servlet is configured with specific initialization parameters, these parameters can be accessed within the servlet using the getInitParameter() method, allowing customization of the servlet's behavior based on the configuration.
