Which of the following types of disaster recovery sites will have the highest MTTR if needed for operations during an outage?

A warm site has partially configured hardware and recent backups, so recovery takes hours to days - less time than a cold site, resulting in a lower MTTR.

A geoclustered site maintains active or standby nodes in geographically separate locations with near-real-time data sync, providing very low MTTR through near-instant failover.

A redundant site (equivalent to a hot site) mirrors the production environment fully and can assume operations almost immediately, resulting in the lowest possible MTTR.

A cold site offers only the physical space, power, and connectivity - no servers, storage, or network equipment is pre-staged. When activated during an outage, staff must procure, ship, rack, configure, and restore all systems from scratch, resulting in recovery times measured in days to weeks, the highest MTTR of any DR site type.
