switches can redistribute routes across the network.

B.
environmental monitoring can be performed.

C.
single points of failure are removed.

D.
hot and cold aisles are functioning.

Explanation:
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

Incorrect Answers:
A: Redistribution of routes is not the purpose of redundancy.
