200-901 Software Development and Design Practice Question
This 200-901 practice question tests your understanding of software development and design. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
In software architecture, which pattern separates an application into three interconnected components: Model (data), View (UI), and Controller (input logic)?

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
In MVC, the Controller acts as an intermediary: it interprets user input from the View, updates the Model (e.g., via CRUD operations), and then triggers a View update, often through an Observer pattern where the Model notifies Views of changes. A subtle behavior is that in web frameworks like Spring MVC, the Controller returns a logical view name that is resolved by a ViewResolver to an actual template (e.g., JSP, Thymeleaf), decoupling the Controller from the rendering technology. Real-world scenario: In a banking app, the Controller handles a withdrawal request, updates the Account Model (checking balance, deducting funds), and then selects a View to display the updated balance or an error message.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
