Which of the following is a component of a data center disaster recovery plan beyond power and cooling?

• A. Clear RTO/RPO targets, contact lists, backups, alternate site plans, and testing schedules.
• B. Redundant cooling system maintenance calendar.
• C. Facility security policy only.
• D. Electrical wiring schematics.

Answer: (A)

Disaster recovery planning centers on getting operations back online after an outage, not just keeping power and cooling up. A solid DR plan defines clear recovery time and recovery point objectives so teams know how quickly to restore services and how recent data must be, includes current contact lists to coordinate response, specifies how data backups will be restored, lays out alternate site plans for where to run systems if the primary site is unavailable, and schedules regular testing to verify the plan works and to train staff. This combination makes the plan actionable and testable, covering procedures, data protection, and communication in addition to physical infrastructure. The other choices focus narrowly on a single physical or policy aspect, such as a maintenance calendar for cooling, a security policy only, or wiring schematics, which do not provide the full set of recovery procedures and readiness activities.
