Full-interruption--A

Explanation:  The Full-interruption is one of the major steps for  a Disaster Recovery Plan, DRP which ensures businesses are not disrupted by saving valuable resources during a disaster like a data breach from fire or flood.

Although expensive and very risky especially in its simulation of a disruption, this thorough  plan ensures that when a disaster occurs, the  operations are shut down at the primary site and are transferred to the recovery site allowing Individuals follow every procedure, ranging from the interruption of service to the restoration of data from backups, also with the notification of appropriate individuals.
