Auto-configuration could apply when a bean is missing but not when a bean is present.

Auto-configuration is applied by processing candidates listed in META-INF/spring.factories.

Auto-configuration could apply when a bean is present but not when a bean is missing.

Auto-configuration is applied before user-defined beans have been registered.

NEW QUESTION 30
Refer to the exhibit.

Assume that the application is using Spring transaction management which uses Spring AOP internally.
Choose the statement that describes what is happening when the update1 method is called? (Choose the best answer.)

NEW QUESTION 34

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

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

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

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

NEW QUESTION 35
Which two statements describe Spring JdbcTemplate? (Choose two.)

All JdbcTemplate methods throw SQLException which you are required to handle.

The JdbcTemplate can only perform update but not insert to the database.

The JdbcTemplate provides methods for query execution.

The JdbcTemplate generates SQL statements.

NEW QUESTION 36
Which two statements about the @Autowired annotation are true? (Choose two.)

@Autowired fields are injected after any config methods are invoked.

Multiple arguments can be injected into a single method using @Autowired.

By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.

If @Autowired is used on a class, field injection is automatically performed for all dependencies.

@Autowired can be used to inject references into BeanPostProcessor and

NEW QUESTION 37
Which two statements are true regarding bean creation? (Choose two.)

A Spring bean can be explicitly created by annotating methods or fields by @Autowired.

A Spring bean can be implicitly created by annotating the class with @Component and using the component-scanner to scan its package.

A Spring bean can be implicitly created by annotating the class with @Bean and using the component- scanner to scan its package.

A Spring bean can be explicitly created using @Bean annotated methods within a Spring configuration class.

A Spring bean can be explicitly created by annotating the class with @Autowired.

NEW QUESTION 38
Refer to the exhibit.

The above code shows a conditional @Bean method for the creation of a JdbcTemplate bean. Which two statements correctly describe the code behavior? (Choose two.)

@ConditionalOnBean(name= “dataSource”) should be replaced with @ConditionalOnBean (DataSource.class) for greater flexibility.

@ConditionalOnBean(name= “dataSource”) should be replaced with
@ConditionalOnMissingBean (DataSource.class) for greater flexibility.

The @Bean annotation should be removed.

A JdbcTemplate bean will be created when the DataSource class is in the classpath but there is no DataSource bean.

A JdbcTemplate bean will be created when a bean named dataSource has already been created.

NEW QUESTION 39

NEW QUESTION 42
Which two statements are correct regarding the @EnableAutoConfiguration annotation? (Choose two.)

It is a meta-annotation on the @SpringBootApplication composed annotation.

It is meta-annotation on the @SpringBootConfiguration composed annotation.

It has the same effect regardless of the package of the class that is annotated with it.

It ensures auto-configuration is applied before user-defined beans have been registered.

NEW QUESTION 43
Which three statements are advantages of using Spring’s Dependency Injection? (Choose three.)

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

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

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

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

Dependency injection creates tight coupling between components.

Dependency injection facilitates loose coupling between components.

NEW QUESTION 44
