Which of the following best ensures minimal downtime and data loss for organizations with critical computing equipment located in earthquake-prone areas?

Off-site replication is the best option because it creates copies of data and systems at a geographically distant location. In an earthquake, local infrastructure could be completely destroyed, making on-site backups or local redundancies useless. Off-site replication ensures that even if the primary site is lost, a functional copy exists elsewhere, minimizing both downtime and data loss. Generators and UPS provide power continuity but don't protect against physical destruction of equipment. Redundant cold sites offer a recovery location but require significant time to set up and restore operations, leading to substantial downtime. High availability networking focuses on network uptime but doesn't address the physical loss of computing equipment or data.
