What is Spring Boot primarily designed for

• Building large-scale enterprise applications

• Simplifying the setup and development of Spring-based applications

• Managing cloud infrastructure

• Data processing and analytics

Which of the following annotations is used to mark a class as a Spring Boot application

• @SpringBootApplication

• @SpringBootApp

• @EnableAutoConfiguration

• @EnableSpringBoot

How does Spring Boot simplify dependency management?

• By automatically resolving version conflicts among dependencies

• By reducing the number of dependencies required

• By providing a unified way to manage all dependencies using Maven or Gradle

• By eliminating the need for dependencies altogether

Which embedded server does Spring Boot support by default?

• Tomcat

• Glass Fish

• None

• Both

What is dependency injection in the context of Spring Boot?

• A technique to manually instantiate dependencies in Java classes

• A design pattern to manage dependencies between components

• A way to inject external configuration properties into Spring beans

• mechanism to automatically provide objects that another object depends on

Which annotation is used to indicate that a class is eligible for dependency injection in Spring Boot?

• • @Component

• @Autowired

• @Bean

• @Inject

In Spring Boot, what is the purpose of @Qualifier annotation?

• To specify which bean to inject when multiple beans of the same type are available

• To mark a bean as eligible for autowiring

• To specify a bean's initialization method

• To define a custom bean scope

In Spring Boot, what is the purpose of @Primary annotation?

• To mark a bean as the default bean to be injected when no @Qualifier is specified

• To define a bean's initialization order

• To enable circular dependencies between beans

• o specify a bean's scope as singleton

How does Inversion of Control (IoC) relate to dependency injection in Spring Boot?

• IoC is another term for dependency injection in Spring Boot

• IoC is a pattern that encourages the inversion of the control of object creation and management to a container like Spring, which then manages the dependencies

• IoC is a technique to manually resolve dependencies between Java classes

• IoC is not related to dependency injection in Spring Boot

How does Spring Boot support loose coupling between components?

• By using design patterns like Singleton

• By hard-coding dependencies in classes

• By encouraging dependency injection and IoC

• By using static methods for object creation
