Answer:
Redundant
Step-by-step explanation:
A redundant system is one in which you duplicate functions in order to improve the reliability and availability of a system. The system acts as a backup in case of a failure reducing downtime.This can be seen implemented in a network infrastructure where alternative network paths are available in case the primary route fails An example is the Fibre Distributed Data Interface (FDDI) that has a dual ring configuration, with one of the rings being redundant and used as an alternative connection when the primary ring fails.
