A company requires an application recovery time under one hour after regional loss but can tolerate several minutes of data loss. It cannot fund a fully active duplicate. Which strategy should be evaluated first?

1. Pilot light or warm standby sized and tested against the actual RTO and RPO.
2. No alternate Region because Multi-AZ alone covers an entire regional outage.
3. Backup and restore with no timed test and an assumed five-minute recovery.
4. A full active-active copy regardless of cost and application write semantics.
