Which statement correctly defines RPO and RTO in disaster recovery planning?

• A. RPO is the maximum tolerable data loss measured in time; RTO is the maximum acceptable downtime before business continuity is restored.
• B. RPO is the maximum acceptable downtime; RTO is the maximum tolerable data loss.
• C. RPO is the total amount of data stored in backups; RTO is the time to restore from backups.
• D. RPO and RTO refer to network latency targets.

Answer: (A)

RPO and RTO describe how much disruption a business can tolerate in a disaster scenario: how much data you can afford to lose (data loss tolerance) and how quickly you must be back online (downtime tolerance). The correct statement matches this: RPO is the maximum tolerable data loss measured in time, and RTO is the maximum acceptable downtime before business continuity is restored. Understanding this helps shape backup frequency and recovery strategies. If the RPO is 1 hour, you need data protection that ensures you won’t lose more than an hour’s worth of data, so backups or replication should occur at least hourly. If the RTO is 2 hours, your recovery plan must restore services within two hours of an outage, guiding the choice of failover approaches, redundancy, and tested recovery procedures. The other options don’t fit because they swap the concepts, describe different things (like total backup size or restore time), or point to unrelated metrics such as network latency.
