1
What does the Single Responsibility Principle (SRP) advocate for in software design?
Explanation
The Single Responsibility Principle states that a class should have only one reason to change, promoting better maintainability.
2
Which of the following best describes Loose Coupling in software design?
Explanation
Loose Coupling allows components to be independent, enabling modifications without affecting other components.
3

Explanation
The Service Discovery Pattern helps in identifying and managing service instances in a microservices architecture.
6
Which architectural pattern contrasts with microservices by building systems as a single unit?
Explanation
Monolithic Architecture builds systems as a single unit, contrasting with the decentralized nature of microservices.
7
What is a key advantage of scalability strategies in system design?
Explanation
Scalability strategies are crucial for ensuring that systems can handle increased loads effectively.
