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

Question

Options

• 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
• 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.

• A
  5% (1)
• C
  89% (17)
• D

Explanation

There appears to be an error in the provided answer key. Based on Spring Boot and Spring Data JPA documentation, A and B are the true statements, not C and E. Here is the accurate explanation:

Why A is correct: @EntityScan lets you customize which packages are scanned for JPA entities, and spring.jpa.* properties (including spring.jpa.properties.hibernate.*) are the standard way to configure JPA behavior in Spring Boot.

Why B is correct (implied): Hibernate-specific properties can be passed through Spring Boot using the spring.jpa.properties.hibernate.* namespace, forwarding them directly to the underlying Hibernate session factory.

Why C is wrong (a distractor): Spring Data JPA is not the only Spring Data module for relational databases - Spring Data JDBC is another option, and it intentionally bypasses JPA entirely.

Why D is wrong: Entity scanning can be customized using @EntityScan, contradicting this statement directly.

Why E is wrong: Spring Boot does re-create embedded databases (H2, HSQLDB, Derby) by default on startup - the ddl-auto property defaults to create-drop for embedded datasources.

Memory tip: Think "A and B configure, C and D lie, E misleads" - the two customization options (annotation + properties) are the true pair. If your exam source lists C and E as correct, treat it as a flawed question.
