• A. Hot Spare
• B. Cold Site
• C. Warm Site
• D. Hot Site

Answer: (D)

Failover readiness in disaster recovery planning determines how quickly services resume after a failure. A fully operational duplicate of the production environment that can take over within minutes is known as a hot site. It means the site is already configured with hardware, software, and data, and is kept synchronized with the primary system so the switch over causes minimal downtime. This setup delivers near-immediate continuity because everything needed to run is up and running at the backup location. By contrast, a hot spare is a redundant component or device rather than a complete duplicate environment to be used at a separate site. A warm site has the right facilities and some equipment but lacks current data or fully configured software, requiring additional steps to restore services. A cold site provides only space and basic infrastructure, with no active systems until you bring them online.
