What term describes a recovery site with complete duplication of original site resources, ensuring the fastest disaster recovery?

• A. Hot Site Recovery
• B. Cold Site Recovery
• C. Warm Site Recovery
• D. Backup Site Recovery

Answer: (A)

Hot site recovery refers to having a fully provisioned duplicate of the production environment at a separate location, ready to take over with little to no downtime. This means every key resource—the servers, storage, network connections, and current data—exists at the secondary site, so operations can resume almost immediately after a disruption. Because the replica is kept up to date and ready to go, the time to recover (RTO) and the amount of data you’re willing to lose (RPO) are kept to a minimum, delivering the fastest disaster recovery option. Think of what cold sites offer: empty facilities with space to house equipment, which means days or weeks to restore service as hardware is brought in and configured and data is restored from backups. A warm site has some preinstalled infrastructure but isn’t fully prepared to go live without additional setup, so the recovery time is longer than a hot site. A backup site relies on data backups rather than live mirrors, which also slows recovery and can introduce data loss between backups.
