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.)

Question

Exhibit

Options

• 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.

• A
  4% (1)
• C
  91% (21)
• D
  4% (1)

Explanation

When Spring Boot detects spring-boot-starter-jdbc (or spring-jdbc) on the classpath along with an embedded database driver like H2, HSQLDB, or Derby, it automatically wires up both a DataSource bean (pointing to the embedded DB) and a JdbcTemplate bean (using that DataSource) - making C and E correct. No manual @Bean definitions are needed; Spring Boot's DataSourceAutoConfiguration and JdbcTemplateAutoConfiguration handle this entirely.

Why the distractors are wrong:

• A is the direct opposite of the truth - the embedded DB on the classpath is exactly what triggers DataSource auto-configuration.
• B is wrong because JdbcTemplateAutoConfiguration fires whenever a DataSource bean is present (auto-configured or otherwise).
• D inverts the actual dependency: JdbcTemplate depends on DataSource, not the other way around. DataSource is configured independently and does not care whether a JdbcTemplate exists.

Memory tip: Think of it as a chain - embedded DB driver → DataSource → JdbcTemplate. If the first link is on the classpath, Spring Boot auto-builds the whole chain. You only need to break the chain yourself (with spring.datasource.* properties) if you want a non-embedded database.
