Full-Stack Architecture (Questions 1–10)
1. Which architectural pattern separates concerns into presentation,
business logic, and data layers?
A) MVC
, B) MVVM
C) Flux
D) Monolith
A) MVC
Architecture Pattern Explanation: Model (data), View (UI), Controller (logic).
Code Implementation Example:
# Flask MVC
class UserController:
def create_user(self, data):
user = UserModel(data)
user.save()
return UserView.render(user)
2. In a microservices architecture, services communicate via:
A) Shared database
B) HTTP/REST or message queues
C) Direct method calls
D) Global variables
B) HTTP/REST or message queues
Architecture Pattern Explanation: Loose coupling, independent deployment.
Code Implementation Example:
// Axios call to User Service
axios.post('http://user-service:8080/api/users', data)
3. The 2025 full-stack framework of choice for rapid prototyping is:
A) Django + React
B) Next.js (App Router)
C) Spring Boot + Angular
D) Laravel + Vue
B) Next.js (App Router)
Architecture Pattern Explanation: Server Components, SSR, API routes in one project.
Code Implementation Example:
// app/page.tsx
export default async function Home() {
const data = await fetch('http://localhost:3000/api/data').then(r => r.json())
return <div>{data.message}</div>
}
4. What is the purpose of a reverse proxy like Nginx in full-stack apps?
A) Database queries
B) Load balancing, SSL termination, caching
