A Correct answer
Explanation

Server clustering ensures high availability by allowing multiple servers to back each other up - if one fails, others immediately take over with minimal downtime. Hot swap drives protect against disk failure but not server failure. Multiprocessors and scalable storage improve performance but don't guarantee availability.
