Which two statements are true regarding a Spring Boot-based Spring MVC application? (Choose two.)

Question

Options

• AThe default embedded servlet container can be replaced with Undertow.
• BJetty is the default servlet container.
• CSpring Boot starts up an embedded servlet container by default.
• DThe default port of the embedded servlet container is 8088.
• ESpring MVC starts up an in-memory database by default.

• A
  88% (36)
• B
  2% (1)
• D
  2% (1)
• E
  7% (3)

Explanation

C is correct because Spring Boot auto-configures and starts an embedded Tomcat servlet container by default - no external server deployment needed. A is correct because Spring Boot is designed to be swappable: you can exclude spring-boot-starter-tomcat and add spring-boot-starter-undertow (or Jetty) to replace the default container.

B is wrong - Tomcat, not Jetty, is the default; Jetty is an available alternative. D is wrong - the default port is 8080, not 8088 (a common trap). E is wrong - an in-memory database (like H2) only activates if you include the H2 dependency and Spring Data JPA on the classpath; Spring MVC alone does not do this.

Memory tip: Think "Spring Boot = Tomcat by default, port 8080, and swappable" - the number 8080 and the word "Tomcat" should go together in your mind, making both the wrong port (8088) and the wrong default container (Jetty) easy to eliminate.
