CISM · Question #952

Which of the following is the BEST way for the organization to ensure server backups at a warm site are properly maintained and usable during a disaster?

The correct answer is D. Use the equipment at the warm site facility to read the backups. The best assurance that backups are properly maintained and usable is to actually validate readability using the warm-site equipment (i.e., perform restore/read tests). Inspections and reviews don’t confirm the backups can be successfully accessed and restored during a disaster.
