A company recently experienced data loss when a server crashed due to a midday power outage.
Which of the following should be used to prevent this from occurring again?
Redundancy refers to systems that either are duplicated or fail over to other systems in the event of a
malfunction (in this case a power outage). Failover refers to the process of reconstructing a system or switching
over to other systems when a failure is detected. In the case of a server, the server switches to a redundant
server when a fault is detected. This strategy allows service to continue uninterrupted until the primary server
can be restored.
