NEW QUESTION # 13
Which statement is true about the @PropertySource annotation? (Choose the best answer.)

• A. Used to designate the location of the application.properties file in a Spring Boot application.
• B. Used to easily look up and return a single property value from some external property file.
• C. Used to add a set of name/value pairs to the Spring Environment from an external source.
• D. Used to designate the file directory of the application.properties file in a Spring Boot application.

Answer: C

Explanation:
This is true because the @PropertySource annotation provides a convenient and declarative mechanism for adding a PropertySource to Spring's Environment. A PropertySource is an abstraction for a source of name/value pairs that can be used by the Environment to resolve properties. The @PropertySource annotation can be used to load properties from an external file, such as a .properties or .yml file, and make them available to the application context.

NEW QUESTION # 16
Spring puts each bean instance in a scope. What is the default scope? (Choose the best answer.)

• A. prototype
• B. request
• C. session
• D. singleton

Answer: D

Explanation:
Spring supports different scopes for bean instances, such as singleton, prototype, request, session, etc. The scope determines how many instances of a bean are created and how they are shared among other components. The default scope is singleton, which means that only one instance of a bean is created per application context and it is shared by all components that depend on it.

• A. Test methods in a @SpringBootTest class are transactional by default.
• B. @SpringBootTest is typically used for integration testing.
• C. @TestApplicationContext is used to define additional beans or customizations for a test.
• D. Test methods annotated with @SpringBootTest will recreate the ApplicationContext.
• E. @SpringBootTest without any configuration classes expects there is only one class annotated with @SpringBootConfiguration in the application.

Answer: B,E

NEW QUESTION # 18
Which statement describes the @AfterReturning advice type? (Choose the best answer.)

• A. Typically used to prevent any exception, thrown by the advised method, from propagating up the call-stack.
• B. The advice is invoked only if the method returns successfully but not 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. The @AfterReturning advice allows behavior to be added after a method returns even if it throws an exception.

Answer: B

NEW QUESTION # 20
Which dependency enables an automatic restart of the application as code is changed during development of a Spring boot configuration on a web application? (Choose the best answer.)

• A. spring-boot-starter-devtools
• B. spring-boot-initializr
• C. spring-boot-restart
• D. spring-boot-devtools

Answer: A

Explanation:
Spring Boot provides a set of tools for improving the development experience, such as automatic restart, live reload, remote debugging, etc. These tools are included in the spring-boot-starter-devtools dependency, which can be added to the project's pom.xml or build.gradle file. The automatic restart feature will monitor the classpath for changes and trigger a restart of the application when necessary.

NEW QUESTION # 21
Which three statements are advantages of using Spring's Dependency Injection? (Choose three.)

• A. Dependency injection facilitates loose coupling between components.
• B. Configuration can be externalized and centralized in a small set of files.
• C. Dependency injection creates tight coupling between components.
• D. Dependency injection can make code easier to trace because it couples behavior with construction.
• E. Dependencies between application components can be managed external to the components.
• F. Dependency injection reduces the start-up time of an application.

Answer: A,B,E

Explanation:
C . Dependencies between application components can be managed external to the components.
This is true because dependency injection allows the application components to declare their dependencies without creating or obtaining them directly. Instead, the dependencies are provided by an external entity, such as the Spring container, which can read the configuration from XML files, annotations, or Java code1.
D . Configuration can be externalized and centralized in a small set of files.
This is true because dependency injection enables the separation of concerns between the application logic and the configuration. The configuration can be stored in a small number of files that can be easily changed without affecting the source code2.
F . Dependency injection facilitates loose coupling between components.
This is true because dependency injection reduces the direct dependencies between components, making them more reusable and testable. It also allows for easier substitution of different implementations of the same interface3.

NEW QUESTION # 27
Which two options are REST principles? (Choose two.)

• A. RESTful applications favor tight coupling between the clients and the servers.
• B. RESTful applications use a stateless architecture.
• C. RESTful application servers keep track of the client state.
• D. RESTful application use HTTP headers and status codes as a contract with the clients.
• E. RESTful applications cannot use caching.

Answer: B,D

Explanation:
REST stands for Representational State Transfer, which is an architectural style for designing web services that adhere to certain principles. One of these principles is statelessness, which means that each request from a client to a server must contain all the information necessary to understand the request, and that no session state is maintained on the server side. Another principle is uniform interface, which means that clients and servers communicate using a standardized protocol, such as HTTP, and use its features, such as headers and status codes, to exchange information about the resources and their representations.

NEW QUESTION # 28
Which statement is true? (Choose the best answer.)

• A. @ActiveProfiles is a class-level annotation that is used to declare which bean definition profiles should be active when loaded an ApplicationContext for an integration test.
• B. @ActiveProfiles is a class-level annotation that you can use to configure the locations of properties files and inlined properties to be added to the set of PropertySources in the Environment for an ApplicationContext loaded for an integration test.
• C. @ActiveProfiles is a class-level annotation that you can use to configure how the Spring TestContext Framework is bootstrapped.
• D. @ActiveProfiles is a class-level annotation that is used to instruct the Spring TestContext Framework to record all application events that are published in the ApplicationContext during the execution of a single test.

Answer: A

NEW QUESTION # 29
Which two statements about the @Autowired annotation are true? (Choose two.)

• A. @Autowired can be used to inject references into BeanPostProcessor and
• B. Multiple arguments can be injected into a single method using @Autowired.
• C. @Autowired fields are injected after any config methods are invoked.
• D. If @Autowired is used on a class, field injection is automatically performed for all dependencies.
• E. By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.

Answer: B,E

Explanation:
BeanFactoryPostProcessor.
Explanation:
https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/beans/factory/annotation/Autowired.html B . Multiple arguments can be injected into a single method using @Autowired.
This is true because the @Autowired annotation can be applied to methods with arbitrary names and multiple arguments, as shown in the example in Using @Autowired.
C . By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.
This is true because the @Autowired annotation has a required attribute that is true by default, meaning that the dependency is mandatory. If Spring cannot find a matching bean to inject, it will throw a BeanCreationException, which is a subclass of RuntimeException. To avoid this exception, we can set the required attribute to false, which will allow Spring to skip the injection if no matching bean is found

NEW QUESTION # 30
Which two statements are true about Spring Boot and Spring Data JPA? (Choose two.)

• A. Any kind of Hibernate property can be passed to Spring Data JPA like spring.jpa.properties.xxx.
• B. @EntityScan and spring.jpa.* properties can be used to customize Spring Data JPA.
• C. Scanning of JPA Entities can not be customized, the whole classpath is scanned.
• D. Embedded Databases (H2, HSQLDB, Derby) are not re-created during the startup.
• E. Spring Data JPA is the only implementation for relational databases.

Answer: D,E

NEW QUESTION # 31
If a class is annotated with @Component, what should be done to have Spring automatically detect the annotated class and load it as a bean? (Choose the best answer.)

• A. Ensure a valid @ComponentScan annotation in the Java configuration is specified.
• B. Ensure a valid @Bean for the class is specified.
• C. Ensure a valid @Scope for the class is specified.
• D. Ensure a valid bean name in the @Component annotation is specified.

Answer: A

Explanation:
The @Component annotation indicates that a class is a candidate for auto-detection by Spring and can be registered as a bean in the application context. However, to enable this feature, the Java configuration class must also have the @ComponentScan annotation, which tells Spring where to look for annotated components.

NEW QUESTION # 32
Which two options are REST principles? (Choose two.)

• A. RESTful applications favor tight coupling between the clients and the servers.
• B. RESTful applications use a stateless architecture.
• C. RESTful application servers keep track of the client state.
• D. RESTful application use HTTP headers and status codes as a contract with the clients.
