• Question 128:

  A web app must be accessible from computers and mobile devices. It must maintain the same data structure on both types of devices. What is the advantage of using the MVC design pattern for this app?

  A. to asynchronously update the graphical interface

  B. to define different algorithms for data manipulation

  C. to separate the logic of the graphic interface of the different devices

  D. to have only one instance of the objects that contain the data

  Correct Answer: C

  The MVC (Model-View-Controller) design pattern is a software architecture pattern commonly used in web development to separate an application into three interconnected components: Model, View, and Controller.

  In this case, using the MVC design pattern can help in separating the logic of the graphic interface of the different devices, as the View component can be customized for the different devices while maintaining the same underlying data structure in the Model component. This can make it easier to maintain and update the application, as changes to the interface of one device will not affect the data or interface of the other devices.
