In OT disaster recovery, what does RTO represent?

• A. The maximum allowable downtime.
• B. The maximum tolerable data loss.
• C. The recovery time for software.
• D. The time to recover hardware.

Answer: (A)

RTO is the maximum duration the OT system can be down after a disruption and still allow the organization to operate safely and meet its objectives. In OT environments, downtime can threaten safety systems, regulatory compliance, and production, so the RTO sets the time limit for restoring services and resuming operations. It guides how quickly recovery efforts must work, informs staffing and process priorities, and shapes the overall disaster recovery plan. The other concept, the maximum tolerable data loss, describes how much data you can afford to lose (data loss tolerance), not how long the system can be offline. And treating recovery time as only software or only hardware recovery misses the broader goal of returning the entire operation to an acceptable state, which is what RTO captures.
