Section: Compliance and Operational Security

Redundancy refers to systems that either are duplicated or fail over to other systems in the event of a malfunction. The best way to remove an SPOF from your environment is to add redundancy.

Incorrect Answers:
A: Redistribution of routes is not the purpose of redundancy.
B: Environmental monitoring is concerned with water and flood damage as well as fire suppression and redundancy is concerned with availability of resources.
D: Hot and cold aisles in server rooms are concerned with cooling the servers and equipment in the server room.
