Organizational Tolerance for Downtime

A.

The specified parameter in the given scenario is the Recovery Time Objective (RTO).

RTO refers to the maximum time duration within which an organization must recover its systems and resume normal operations after a disruption or outage occurs. In other words, it is the time limit that an organization has determined it can tolerate for its systems to be offline before the impact becomes unacceptable.

In this case, the organization has specified a maximum tolerable downtime of three hours. Therefore, it implies that the organization's RTO is three hours or less.

The other options given in the question are:

• Recovery Point Objective (RPO): It refers to the maximum tolerable data loss that an organization can sustain after a disruption. RPO is concerned with restoring data to a point in time before the disruption occurred.
• Mean Time Between Failures (MTBF): It is a metric that calculates the average time duration between two successive system failures. It is used to predict the reliability of a system.
• Mean Time to Repair (MTTR): It is a metric that measures the average time duration required to repair a system after a failure has occurred.

None of these options are related to the specified time limit for downtime, which is the Recovery Time Objective (RTO).
