A bank sets its recovery time objective (RTO) for its internet banking platform at 2 hours. What does this mean?
An RTO of 2 hours means the internet banking platform must be restored within two hours of a disruption. It measures acceptable downtime. The acceptable amount of data loss, measured in time, is a separate measure called the recovery point objective.
- AThe maximum acceptable amount of data loss measured in time is 2 hours
- BThe maximum acceptable time within which the service must be restored after disruption is 2 hoursCorrect
- CThe platform must be audited every 2 hours
- DIncidents must be reported to the regulator within 2 hours
Explanation
RTO is the target duration within which a service must be restored after an outage. The maximum tolerable data loss measured in time is the recovery point objective (RPO), which is the first option's meaning. Audit frequency and regulatory reporting are unrelated concepts.
