D.
Recovery Tolerable Downtime
Explanation:
The Recovery Time Objective (RTO) defines the maximum amount of time
that a system resource can remain unavailable before there is an unacceptable impact
on other system resources, supported mission/business functions, and the MTD.
Determining the information system resource RTO is important for selecting
appropriate technologies that are best suited for meeting the MTD.
I DISAGREE!!!
The maximum tolerable downtime (MTD), sometimes also known as maximum tolerable outage (MTO). The MTD is the maximum length of time a business function can be inoperable without causing irreparable harm to the business. The MTD provides valuable information when you’re performing both BCP and DRP planning.
This leads to another metric, the recovery time objective (RTO), for each business function. This is the amount of time in which you think you can feasibly recover the function in the event of a disruption.
