Which of the following will be the BEST option for an administrator to bring VMs online at a warm site after a natural disaster has occurred at the primary site?

Initiating a full backup during an active disaster recovery event is counterproductive because the objective is to restore VMs from existing backups, not generate new ones from a site that has already suffered an outage.

Requesting offsite backup tapes is a valid follow-on step but is premature as an initial action if the tape library at the warm site has not yet been verified as functional.

A warm site provides pre-configured hardware and infrastructure but relies on backup media - typically tape - to restore VM data after a primary site failure. The enterprise tape library is the mechanism through which backed-up VM images and data are read and loaded onto the warm site systems. Confirming the tape library is operational is the mandatory prerequisite before any recovery jobs can be initiated, as a non-functional library makes all available backup tapes unusable.

Verifying replication status after a disaster has occurred is too late to be actionable; replication must have been confirmed active before the disaster for it to support any recovery effort at the warm site.
