A failure of the primary data center has occurred. A warm site is available for use. Which of the following should be done FIRST to bring the critical applications online?

Running cabling and power is characteristic of a cold site; a warm site already has infrastructure in place.

A warm site typically has pre-installed hardware and network connectivity, but it requires data to be restored to the equipment before applications can function. Restoring data is the most critical first step to make applications functional after the physical site is ready.

While data tapes might be involved, the primary action is to restore the data to the systems at the warm site, assuming the tapes have already been transported or data is available via other means.

Testing with least critical applications is an important step, but it cannot be done until after data has been restored and applications have been configured on the systems.
