A. {id}encodedPassword, where {id} is an identifier used to look up which PasswordEncoder should be used.

B. {id}{salt}encodedPassword, where {id} is an identifier used to look up which PasswordEncoder should be used and {salt} a randomly generated salt.

C. encodedPassword{id}, where {id} is an identifier used to look up which PasswordEncoder should be used.

D. {timestamp}encodedPassword, where {timestamp} is the time when the password was encoded.

A. The ApplicationContext is the root interface for accessing the Spring container.

B. The ApplicationContext maintains singleton beans that are instantiated by the Spring runtime.

C. The ApplicationContext lazy initializes beans by default.

D. The ApplicationContext can be created in a test environment, web application, and in a standalone application.

E. The ApplicationContext does not include all functionality of the BeanFactory.

A. Enable component scanning within auto-configuration classes to find necessary components.

B. Use the @AutoConfigureAfter or @AutoConfigureBefore annotations to apply configuration in a specific order.

C. Disable specific auto-configuration classes by using the exclude attribute on the
@EnableAutoConfiguation annotation.

D. Provide customized auto-configuration by subclassing the provided Spring Boot auto-configuration classes.

E. Control the order of auto-configuration classes applied with @AutoConfigureOrder.

A. Custom BeanPostProcessors can be implemented for Spring applications.

B. BeanPostProcessors are called before the dependencies have been injected.

C. BeanPostProcessors are called before the BeanFactoryPostProcessors.

D. BeanPostProcessors are called during the initialization phase of a bean life cycle.

E. BeanPostProcessors cannot be ordered in a Spring Boot application.

A. The user details includes username and password but not authorities.

B. With a custom UserDetailsService defined in the ApplicationContext, Spring Boot still creates the default user.

C. User details can be stored in custom storage and retrieve them by implementing the UserDetailsService interface.

D. User details can be stored in a database, in LDAP, or in-memory.

E. Passwords must be hashed and the default hashing algorithm is MD5.

A. Mocks cannot be used in a Spring Boot web slice test.

B. Mocking a Spring Bean requires annotating it with @Mock annotation.

C. If a Spring Bean already exists in the web slice test spring context, it cannot be mocked.

A. Test methods in a @SpringBootTest class are transactional by default.

B. @SpringBootTest without any configuration classes expects there is only one class annotated with @SpringBootConfiguration in the application.

C. @SpringBootTest is typically used for integration testing.

D. @TestApplicationContext is used to define additional beans or customizations for a test.

E. Test methods annotated with @SpringBootTest will recreate the ApplicationContext.

A. Configuration can be externalized and centralized in a small set of files.

B. Dependency injection can make code easier to trace because it couples behavior with construction.

C. Dependencies between application components can be managed external to the components.

D. Dependency injection reduces the start-up time of an application.
