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
were used to connect to the hubs and are manually configured for 10Mb half-duplex. The
PCs were connected to the switch and were manually configured for 100 Mb full-duplex.
What could have been done to avoid this issue?
A. Auto-negotiation only needed to be enabled on the switch.
B. Auto-negotiation should have been enabled on the switch ports and on the PCs.
C. Auto-sensing only needed to be enabled on the switch.
D. Auto-sensing should have been enabled on the switch ports and on the PCs.
