The Pilot Light strategy is correct because it involves having a minimal version of an environment always running in the cloud. This strategy allows a company to rapidly scale up this environment to handle full production load in the event of a disaster, ensuring minimum data loss and rapid recovery. The Warm Standby strategy is more costly as it involves a scaled-down but fully functional version of the environment. Both the Backup and Restore and Active-Active strategies do not fit the criteria as well as Pilot Light; Backup and Restore can involve more extensive data loss and longer recovery times, while Active-Active requires full production-scale environments in two locations, significantly increasing cost.
