Question 1 of 40Assessment

How does the 'volatile-lfu' eviction policy fundamentally differ from 'volatile-lru' when the 'maxmemory' limit is reached?

A. It evicts keys with an expire set based on their access frequency rather than the time elapsed since last access.

B. It targets all keys regardless of expiration, prioritizing those with the largest memory footprint in the dataset.

C. It removes keys that have the shortest remaining time to live (TTL) regardless of their actual access frequency.

D. It utilizes a randomized sampling of keys to find the least recently used entry across the entire keyspace.
