An organization recently had a disaster and the data center failed over to the backup site. The original data center has been restored and the administrator needs to migrate the organization back to the primary data center. What process is the administrator performing?
A. Failover
B. Failback
C. DRP
D. RTO
Answer: B
Failback is the process of restoring operations to a primary machine or facility after they have been shifted to a secondary machine or facility during failover. During a site-wide failover, I/O (input/output) and its processes are shifted from a primary location to a temporary disaster recovery (DR) location.
(DRP). Disaster recovery planning is a subset of a larger process known as business continuity planning and includes planning for resumption of applications, data, hardware, electronic communications (such as networking) and other IT infrastructure.
The recovery time objective (RTO) is the targeted duration of time and a service level within which a business process must be restored after a disaster (or disruption) in order to avoid unacceptable consequences associated with a break in business continuity.
