Which of the following is the correct mechanism for using programmatic transactions in Spring? (Select one)

• A.Use of the @Transactional annotation on the Class of methods which should all be transactional
• B.Configuration in an XML configuration file using the Spring "tx" namespace
• C.Use of the Spring TransactionTemplate
• D.Use of the @Transactional annotation on each method which should be transactional

@Configuration
public class AppConfig {
@Bean
public ClientService clientService() {
ClientServiceImpl clientService = new ClientServiceImpl();
clientService.addClientDao(new ClientDao());
return clientService;
}
In the example above, which statement is NOT true with regards to Spring Java configuration?
(select one)

• A.The declared bean is a singleton by default
• B.This bean cannot use a method starting with "add" to inject a dependency
• C.The bean is of type ClientService
• D.This bean might be wrapped by a proxy

Which of the following statements is NOT true with respect to Spring's ApplicationContext? (select one)

• A.When available, the close() method will cause any registered bean destruction code to be invoked
• B.In a JUnit test using Spring support (with @ContextConfiguration annotation), it is necessary to close the ApplicationContext manually
• C.The ApplicationContext eagerly instantiates all singleton beans by default
• D.There are many different implementation classes which all implement the ApplicationContext interface

Consider the following bean definition
<bean id="clientService" class="com.springsource.service.ClientServiceImpl" />
Using Spring AOP, you have declared a Pointcut targeting all methods inside the clientService bean. ClientServiceImpl implements 3 different interfaces.
Which interfaces will the proxy class implement? (Select one)

• A.The proxy class does not implement any interface
• B.All interfaces
• C.A Spring bean should never implement any interface

Which of the following are valid mechanisms of autowiring a dependency when multiple beans match the dependency's type? (Select one or several answers)

• A.Use of the @Qualifier and @Autowired annotations together with setter methods
• B.Use of the @Qualifier and @Autowired annotations together on a field
• C.Use of the @Qualifier annotation solely
