Check your understanding of designing microservices using Spring Boot and Spring Cloud.
1. What is the primary purpose of Spring Boot in microservices architecture?
Simplify setup and reduce boilerplate code
Manage database transactions across services
Provide frontend UI components
Encrypt inter-service communication
2. Which of the following are core components of Spring Cloud for microservices?
Eureka
Config Server
Gateway
Hibernate
3. Microservices architecture promotes a single shared codebase for all services.
True
False
4. What key functionality does Eureka provide in Spring Cloud (one word)?
5. Which design pattern helps prevent cascading failures when a downstream microservice is unresponsive?
Circuit Breaker
Load Balancing
API Gateway
Service Registry
6. Which are key benefits of microservices over monolithic architecture?
Independent service deployment
Technology stack diversity
Simplified debugging
Granular scalability
7. Spring Cloud Config Server allows centralized management of microservice configurations.
True

8. Name the Spring Boot starter dependency used to build RESTful web services (full name, hyphenated).
9. What is the primary role of Spring Cloud Gateway in microservices?
Route client requests to appropriate microservices
Persist data across distributed transactions
Authenticate users for all services
Generate API documentation
10. Which are characteristics of well-designed microservices?
Loosely coupled with other services
Focused on a single business capability

@MicroserviceRegistry
14. Which technologies are commonly used for inter-service communication in Spring Boot microservices?
REST over HTTP/JSON
gRPC
Kafka (event-driven)
JDBC
15. Spring Boot's auto-configuration feature eliminates the need for most manual XML or Java-based configuration.
True
False

Config Server
Eureka
Gateway
Resilience4j
18. Which are common challenges in microservices architecture?
Distributed transaction management
Network latency between services
Independent service deployment
Service discovery complexity
19. A microservice should typically handle multiple unrelated business capabilities to maximize efficiency.
True
False
20. Name the architectural pattern that provides a single entry point for all client requests to microservices.
