Salesforce Platform Developer Practice Exam

How is Model-View-Controller (MVC) architecture implemented on the Salesforce platform?

1. Model: Standard and Custom Objects; View: Visualforce Pages; Controller: s-Controls

2. Model: Schema Builder; View: List Views; Controller: Setup Console

3. Model: Standard and Custom Objects; View: Visualforce Pages; Controller: Apex Code

4. Model: Apex Code; View: List Views; Controller: Setup Console

The correct answer is: Model: Standard and Custom Objects; View: Visualforce Pages; Controller: Apex Code

The implementation of Model-View-Controller (MVC) architecture on the Salesforce platform is correctly described by identifying the elements in the context of their specific functions within the architecture. In this approach, the Model refers to the data structure, which includes Standard and Custom Objects in Salesforce. These objects represent the data that applications will use, serving as the foundation for the data model in the Salesforce ecosystem. The View component is represented by Visualforce Pages. Visualforce is a framework that allows developers to create user interfaces that can display and interact with the underlying data represented by the Model. It provides a way to render and format data on the user interface, making it essential for the 'View' aspect of MVC. The Controller in the MVC architecture is represented by Apex Code. Apex is the programming language for the Salesforce platform, and it enables developers to write code that implements the logic and controls the interactions between the Model and the View. The controller is responsible for processing user inputs, managing data flow, and making decisions about how to manipulate the data or respond to user actions. In summary, the correct choice accurately delineates the roles and responsibilities of the three components of the MVC architecture within the Salesforce platform, demonstrating a clear understanding of how each component interacts with and supports
