200-901 Software Development and Design Practice Question
In software architecture, which pattern separates an application into three interconnected components: Model (data), View (UI), and Controller (input logic)?
⚠ Common exam trap
Cisco often tests that candidates confuse MVC with REST or Microservices because both involve separation of concerns, but MVC is specifically about internal component separation within a single application, not about service decomposition or API design.

Correct answer & explanation
✓
MVC (Model-View-Controller)
The MVC pattern explicitly separates an application into three interconnected components: Model (data and business logic), View (user interface), and Controller (handles user input and updates the Model/View). This is the foundational architectural pattern for many web frameworks like Django, Ruby on Rails, and Spring MVC, where the Controller receives HTTP requests, interacts with the Model, and selects the appropriate View for rendering.
