Final answer:
The Hot Site approach to disaster recovery provides the shortest RTO by maintaining a fully operational, duplicate environment that is always on standby, ensuring near-zero data loss and downtime.
Step-by-step explanation:
The disaster recovery approach with the shortest recovery time objective (RTO) is known as Hot Site. This strategy entails maintaining a duplicate, fully operational environment that can take over operations almost immediately after a disaster occurs. Compared to other methods such as Warm Sites or Cold Sites, which require more time to become fully operational, a Hot Site is always on standby, with data continuously mirrored or replicated from the primary site.
With a Hot Site, organizations can achieve near-zero data loss and downtime, as systems and data are kept in sync. In essence, it provides the fastest path to recovery and resumption of business activities post-disaster. Therefore, a Hot Site is considered the superior option for organizations requiring high availability and minimal disruption.
