A. B. C. D.D.
The correct metric that relates to the specified requirement of the data available at the disaster recovery site not being more than 24 hours old is RPO (Recovery Point Objective).
RPO is the maximum duration of time within which the data loss should not exceed. It specifies the amount of data loss that an organization can tolerate in the event of a disaster or disruption.
In this case, the business requirement of having data not more than 24 hours old means that the organization can tolerate a maximum data loss of 24 hours. Therefore, the RPO is 24 hours, which is the acceptable maximum limit of data loss.
RTO (Recovery Time Objective) refers to the duration of time within which the systems and applications should be restored after a disaster or disruption. It is the maximum acceptable downtime for a system or application. While RTO is important for determining how quickly the systems should be restored, it is not directly related to the data loss or the age of the data.
MTBF (Mean Time Between Failures) is a metric that calculates the average time between the failures of a system or component. It is useful in predicting the reliability of a system or component and planning maintenance activities. However, it is not directly related to data loss or the age of the data.
MTTR (Mean Time to Repair) is the average time taken to repair a failed system or component. It is used to measure the efficiency of the IT support team in resolving issues. Again, it is not directly related to data loss or the age of the data.
Therefore, the correct metric that relates to the specified requirement is RPO.
