Selected Answer: B
Hot swaps (option D) involve replacing a failed component with a pre-installed spare component while the system remains operational. While hot swaps can contribute to availability by reducing the time needed to replace failed components, they do not necessarily ensure the same level of redundancy and immediate failover as real-time replication.
