A department was moved from one floor to another. When the department was on the old
floor, the users connected through a mixture of 10 Mb hubs and 10/100 Mb switches.
When the department was moved all the hubs were replaced by 10/100 Mb switches.
Two of the users are reporting that the network is much slower on the new floor even
though the hubs were replaced. You discover that the switch ports these users connect to

PCs were connected to the switch and were manually configured for 100 Mb full-duplex.
What could have been done to avoid this issue?
