Question 1

Which two statements about BeanFactoryPostProcessors are true? (Choose two.)

AAllows for the transformation of Spring bean definitions after the beans have been instantiated.

BAllows for the transformation of Spring bean definitions before the beans are instantiated.

CCreates proxies for the Spring beans that require an extra behavior like transaction management.

DPropertySourcesPlaceholderConfigurer implements BeanFactoryPostProcessor and is used to read property values from the Spring Environment.

EDetects annotations such as @PostConstruct and @PreDestroy and then invokes appropriate behavior.

Answer : B, D

(1) BeanFactoryPostProcessor (Spring Framework 6.1.3 API). https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/beans/factory/config/BeanFactoryPostProcessor.html. (2) Spring BeanPostProcessor | Baeldung. https://www.baeldung.com/spring-beanpostprocessor.

Question 2

In which three ways are Security filters used in Spring Security? (Choose three.)

ATo provide risk governance.

BTo drive authentication.

CTo manage application users.

DTo provide a logout capability.

ETo enforce authorization (access control).

FTo encrypt data.

Answer : B, D, E

Spring Security uses a filter-based architecture to provide security services for web applications. A filter is an object that intercepts HTTP requests and responses and performs some logic before or after the request is processed by the servlet. Spring Security provides a number of filters for different purposes, such as:

Authentication: Filters that handle the authentication process, such as UsernamePasswordAuthenticationFilter, BasicAuthenticationFilter, RememberMeAuthenticationFilter, etc.

User management: Filters that manage the user details and roles, such as SecurityContextPersistenceFilter, AnonymousAuthenticationFilter, ConcurrentSessionFilter, etc.

Logout: Filters that handle the logout process, such as LogoutFilter and SecurityContextLogoutHandler.

Authorization: Filters that enforce access control rules based on the user's authentication and roles, such as FilterSecurityInterceptor, ExceptionTranslationFilter, etc.

Question 3

Which two options are valid optional attributes for Spring's @Transactional annotation? (Choose two.)

Aisolation

BwriteOnly

CnestedTransaction

DreadWrite

Epropagation

Answer : A, E

https://www.baeldung.com/transaction-configuration-with-jpa-and-spring

@Transactional(propagation = Propagation.SUPPORTS, readOnly = true)

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/transaction/annotation/Transactional.html

Question 4

Refer to the exhibit.

Which two statements are correct regarding auto-configuration of DataSource and JdbcTemplate beans given a Spring Boot application with only these two dependencies? (Choose two.)

AA DataSource bean will not be auto-configured.

BA JdbcTemplate bean will not be auto-configured.

CA JdbcTemplate bean will be auto-configured.

DA DataSource bean will be auto-configured only if a JdbcTemplate bean is explicitly defined.

EA DataSource bean will be auto-configured.

Answer : C, E

Question 5

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

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

BIt enables auto-configuration of the ApplicationContext by attempting to guess necessary beans.

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

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

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

Answer : A, B

Enable auto-configuration of the Spring Application Context, attempting to guess and configure beans that you are likely to need https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/EnableAutoConfiguration.html

Question 6

Which two statements are true regarding Spring Security? (Choose two.)

AAccess control can be configured at the method level.

BA special Java Authentication and Authorization Service (JAAS) policy file needs to be configured.

CAuthentication data can be accessed using a variety of different mechanisms, including databases and LDAP.

DIn the authorization configuration, the usage of permitAll () allows bypassing Spring security completely.

EIt provides a strict implementation of the Java EE Security specification.

Answer : A, C

Spring Security is a framework that provides comprehensive security services for Java applications, such as authentication, authorization, encryption, session management, and more. One of its features is method security, which allows applying access control rules at the method level using annotations or XML configuration. Another feature is authentication, which is the process of verifying the identity of a user or a system. Spring Security supports various authentication mechanisms, such as username and password, tokens, certificates, etc., and can access authentication data from different sources, such as databases, LDAP directories, in-memory stores, etc.

Question 7

Which two statements are true about Spring Boot and Spring Data JPA? (Choose two.)

A@EntityScan and spring.jpa.* properties can be used to customize Spring Data JPA.

BAny kind of Hibernate property can be passed to Spring Data JPA like spring.jpa.properties.xxx.

CSpring Data JPA is the only implementation for relational databases.

DScanning of JPA Entities can not be customized, the whole classpath is scanned.

EEmbedded Databases (H2, HSQLDB, Derby) are not re-created during the startup.

Answer : A, B

A . @EntityScan and spring.jpa.* properties can be used to customize Spring Data JPA.

This is true because the @EntityScan annotation can be used to specify the base packages to scan for JPA entities, instead of using the default package of the main application class. The spring.jpa.* properties can be used to configure various aspects of Spring Data JPA, such as the database platform, the DDL generation, the show-sql flag, etc.

B . Any kind of Hibernate property can be passed to Spring Data JPA like spring.jpa.properties.xxx.

This is true because Spring Data JPA supports passing any Hibernate-specific property by using the prefix spring.jpa.properties. For example, we can use spring.jpa.properties.hibernate.format_sql=true to format the SQL statements generated by Hibernate.
