Interview, certification, and glossary
The published Broadcom Spring Professional Develop guide (last
updated 2024-01-26) describes exam 2V0-72.22: 60 items, 130
minutes, and a scaled passing score of 300. It covers Core, Data, MVC,
Testing, Security, and Boot. The same guide references Spring Framework
5.3 and Spring Boot 2.5, so verify the live registration portal before
paying.
This site's 60-question mock uses the official item count and duration as a format benchmark, but teaches current Spring concepts and contains only original questions.

Final Feynman challenge
Draw one request from HTTP through security, controller, service, transaction, repository, outbox, message, and external adapter. Explain where Spring creates objects, where a proxy adds behavior, where failures roll back, and where retries are safe. Anything unclear is your next study target.
