Suggested answer: C

Explanation:

Definition of RPO:

Recovery Point Objective (RPO) is a disaster recovery metric that describes the maximum acceptable amount of data loss measured in time. It indicates the point in time to which data must be recovered to resume normal operations after a disaster.

For example, if the RPO is set to 24 hours, then the business could tolerate losing up to 24 hours' worth of data in the event of a disruption.

Why RPO is Important:

RPO is critical for determining backup frequency and helps businesses decide how often they need to back up their data. A lower RPO means more frequent backups and less potential data loss.

Comparison with Other Metrics:

MTTR (Mean Time to Repair): Refers to the average time required to repair a system or component and return it to normal operation.

RTO (Recovery Time Objective): The maximum acceptable length of time that a computer, system, network, or application can be down after a failure or disaster occurs.

MTBF (Mean Time Between Failures): The predicted elapsed time between inherent failures of a system during operation.

How RPO is Used in Disaster Recovery:

Organizations establish RPOs to ensure that they can recover data within a timeframe that is acceptable to business operations. This involves creating a backup plan that meets the RPO requirements.
