What are cross-cutting concerns in software development?
Cross-cutting concerns are parts of a program that affect multiple components or layers, like logging, security, or error handling. They are not part of the main business logic but are needed everywhere.

How does Spring Boot help manage cross-cutting concerns?
Spring Boot uses Aspect-Oriented Programming (AOP) to separate cross-cutting concerns from business logic. This means you can write code for logging or security once and apply it across many parts of your app.

Give an example of a cross-cutting concern in a web application.
An example is logging user actions. Every time a user clicks a button or sends a request, the app logs it. This logging happens across many parts of the app, not just one place.

What is Aspect-Oriented Programming (AOP) in Spring Boot?
AOP is a way to add extra behavior (like logging or security checks) to existing code without changing it. Spring Boot uses AOP to handle cross-cutting concerns cleanly and separately.

Why is separating cross-cutting concerns important?
Separating them keeps the main code simple and focused. It also makes maintenance easier because changes to logging or security happen in one place, not scattered everywhere.

✗ Incorrect
Separating concerns keeps code clean and easier to maintain.
Which of these is NOT typically a cross-cutting concern?
