A hot site should be implemented as a recovery strategy when the:

A.
disaster tolerance is low.

B.
recovery point objective (RPO) is high.

C.
recovery time objective (RTO) is high.

D.
disaster tolerance is high.

Explanation:
Disaster tolerance is the time gap during which the business can accept nonavailability of IT facilities. If this time gap is low, recovery strategies that can be implemented within a short period of time, such as a hot site, should be used. The RPO is the earliest point in time at which it is acceptable to recover the datA . A high RPO means that the process can wait for a longer time. In such cases, other recovery alternatives, such as warm or cold sites, should be considered. A high RTO means that additional time would be available for the recovery strategy, thus making other recovery alternatives-such as warm or cold sites-viable alternatives.
