Spring Core · interview question
Why do application properties and profiles matter in a production Spring Boot app?
Multiple choiceMediumchapter-9-curatedpremiumspring-coreapplication-properties
Answer and explanation
Correct answer
D. They let the same code run across dev, test, and prod with environment-specific settings
Why
Profiles and externalized properties keep credentials, logging levels, and infrastructure settings out of source code. That is how one application can move safely between local development and production.
