Zach, a technician, discovers a switch is not communicating with the other switches in a stack.
Which of the following is the MOST likely cause?
A.
Both T568A and T568B standards are being used.
B.
STP is disabled.
C.
The cable is not a crossover.
D.
The port is not trunked.
This is just an example of the progress of time and the evolution of networking equipment. Back in the day it used to be mandatory to use a crossover cable between switches and routers and between some servers and hubs, but modern equipment can autosense the connection type and change it’s mdx configuration on a per port basis. Therefore newer training materials will list a standard cable as the proper connection.
An older piece of equipment that may require a cross over cable type of connection.
