I have two designs for the call center in China. The option A is prefer. The option B is suggested by someone.
Which one is better and why?
For the option B, I need to connect two uplink cables to core switch. if "swicth A" is down, the uplink between "switch A" to another floors are down. That's why I need to connect second uplink to "switch B".
However, I do not know the option B to be the "normal design" or not.
