1. What is Hit rate ? Junior A. how frequently entries are forced out, often signaling that capacity is too small for the working set B. the response time experienced by the slowest requests, often dominated by misses and backend fetches C. the fraction of lookups that had to fall back to the underlying data source D. the fraction of lookups served from the fast store rather than the backing source
