______________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.
A.
Maximum Tolerable Downtime
B.
Recovery Time Objective
C.
Recovery Point Objective
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.
Isn’t this MTD?
No. RTO is the amount of time to bring up an individual system without it being ready for production. WRT is the amount of time it takes for the aforementioned system to be configured to be ready for production (perhaps you need to restore backups to it and furthermore bring it up to date with data since the last backup.). WRT+RTO=MTD.
