Chapter Assessment: Getting Started with Spring Boot

This review covers the opening steps of the course: what the container and Spring Boot do when main runs, the files of a generated project, and how the application runs and is packaged. It also covers the booking service and its first race condition. The bank holds 20 questions, and each attempt draws ten. Most questions describe a situation with the booking service, such as a 404 or a second copy that cannot start, and ask for the cause or the fix. Have four things ready: the difference between component scanning and auto-configuration, what the parent decides, the order in which port settings win, and why a check followed by a save fails under overlapping requests. When an answer is wrong, reread the lesson it comes from, and read the explanation on every option.
