Step by Step Explanation: * RPO (Recovery Point Objective): Specifies the maximum acceptable amount of data loss measured in time. If data loss of more than one hour is unacceptable, the RPO should be set to less than or equal to one hour. * RTO (Recovery Time Objective): Refers to the acceptable duration of system downtime, which is not relevant to the question. * The BCP, DRP, and SLA do not directly address data loss.
