Quizplus · Accepted Answer

RAID allows for redundancy in case of hard drive failure, server clustering allows for multiple servers to work together and continue functioning if one fails, and hot-swappable devices allow for easy replacement of faulty components without shutting down the entire system. Resolver cache and SMTP client do not provide fault tolerance.
