A network administrator has recently updated their network devices to ensure redundancy is in
place so that:
A.
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:
A badly drafted question as far as I ca see:
In here a network administrator has recently UPDATED their network devices to ensure redundancy is in place.
Yet, what sort of UPDATE are we talking about?
Updating a router or a switch for example conjures the idea of updating the firmware.
How updating the firmware provide redundancy?
Thankfully, the answers given are so daft that they make reaching to the correct answers easier
Incorrect Answers:
*A- switches can redistribute routes across the network. Route redistribution is when you take a route from one routing protocol and inject it or distribute it into another protocol. This is done by routers and not switches. By default, Routers only advertise and share routes with other routers running the same protocol
*B- Environmental monitoring can be performed. Network devices do not monitor the environment
*D- hot and cold aisles are functioning. Network devices do not monitor the environment. This is done via an HVAC
At the end of the day we are talking about redundancy: Redundancy (engineering), the duplication of critical components or functions of a system with the intention of increasing reliability.
So the only possible answer is : C:- single points of failure are removed.
