# 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.

## Interview frame: SPRING

- **S**cope: user journey, business rule, SLO, security, recovery.
- **P**ackages: domain modules, dependency direction, ownership.
- **R**equest: HTTP/message flow, validation, transaction, errors.
- **I**njection: beans, configuration, lifecycle, proxies.
- **N**on-functional: security, tests, observability, resilience, performance.
- **G**o-live: packaging, migration, rollout, rollback, operations, cost.

## Essential terminology

| Term | Meaning |
|---|---|
| IoC / DI | Inversion of Control / Dependency Injection |
| Bean | Object managed by Spring |
| ApplicationContext | Spring container and application services |
| AOP | Aspect-Oriented Programming |
| MVC | Model-View-Controller servlet web framework |
| WebFlux | Reactive web framework |
| DTO | Data Transfer Object |
| ORM / JPA | Object-relational mapping / Java persistence specification |
| JDBC / R2DBC | Blocking / reactive relational database access APIs |
| SpEL | Spring Expression Language |
| AOT | Ahead-of-Time processing |
| CSRF / CORS | Browser request-forgery defense / cross-origin policy |
| OAuth 2.0 / OIDC | Delegated authorization / identity layer |
| SLI / SLO | Service measurement / reliability target |
| RPO / RTO | Tolerated data loss / restoration time |
| DLQ | Dead-letter queue |

## 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.
