Why each option
The Recovery Time Objective (RTO) is the maximum acceptable period a system can be unavailable after a failure. To ensure services are not down for more than two hours, the administrator must confirm the cloud provider's SLA guarantees an RTO of two hours or less.
Mean Time Between Failures (MTBF) measures the predicted elapsed time between inherent failures of a system during operation and does not directly relate to the time it takes to restore service after a failure.
Recovery Time Objective (RTO) explicitly defines the maximum acceptable duration of service downtime after an incident. An administrator seeking to ensure services are not down for more than two hours must verify that the cloud provider's SLA specifies an RTO equal to or less than two hours.
Recovery Point Objective (RPO) defines the maximum acceptable amount of data that can be lost from a service due to a major incident and does not relate to the duration of service downtime.
Mean Time To Failure (MTTF) is a measure of reliability for systems that are not repaired, indicating the average time until the first failure, and does not relate to recovery time.
