Explain how you would implement a caching mechanism in a Spring Boot application. What strategies would you use to choose which data to cache?

## What to Cover - Discuss caching frameworks (e.g., EHCache, Redis). - Explain data selection criteria for caching – access frequency, data volatility. - Mention invalidation strategies and policies. ## Strong Answer Framework - Outline your thought process in choosing caching strategies based on application requirements. ## Watch Out For - Overlooking edge cases and not considering the implications of cache misses or stale data.
