Which option is true about use of mocks in a Spring Boot web slice test? (Choose the best answer.)

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.)

A. There are 2 transactions because REQUIRES_NEW always runs in a new transaction.

B. An exception is thrown as another transaction cannot be started within an existing transaction.

C. There is only one transaction because REQUIRES_NEW will use an active transaction if one already exists.

Refer to the exhibit.

It is a Java code fragment from a Spring application. Which statement is true with regard to the above example? (Choose the best answer.)

B. It will return a bean called ClientService regardless of its id or name.

C. This syntax is invalid because the bean id must be specified as a method parameter.

D. It will return a bean of the type ClientService regardless of its id or name.

Refer to the exhibit.

Which two statements are correct regarding the HelloAutoConfig auto-configuration class when it is specified in the META-INF/spring.factories file? (Choose two.)

A. A HelloService bean will be created from the helloService() method even if the HelloService.class is not in the classpath.

B. A HelloService bean will be created from the helloService() method only when there is no other HelloService bean in the ApplicationContext.

C. This auto-configuration class is used only when the HelloService.class is not on the classpath.

D. This auto-configuration class is used only when the HelloService.class is on the classpath.

E. A HelloService bean will be created from the helloService() method and will replace existing a HelloService bean in the ApplicationContext.

Which statement describes the @AfterReturning advice type? (Choose the best answer.)

A. The advice is invoked only if the method returns successfully but not if it throws an exception.

B. The @AfterReturning advice allows behavior to be added after a method returns even if it throws an exception.

C. The advice has complete control over the method invocation; it could even prevent the method from being called at all.

D. Typically used to prevent any exception, thrown by the advised method, from propagating up the call-stack.
