You are a technician at Certkiller .com’s main office. You have been sent to a small branch office
to investigate possible upgrades on the network as the users complain about the network being
slow. The branch office network is connected with hubs and have 200 computers on it. Which of
the following would be the BEST upgrade suggestion?

A.
fiber converters

B.
switches

C.
routers

D.
CAT6 cabling

Explanation:
A Ethernet hub forwards all received packets to all ports except the sending port. A switch builds a
table over known MAC addresses and therefore more often only send the packet out the
destination port. This difference makes that switches has a much smaller collision domain and
therefore is much more efficient even if both operate at 100 Mbit/s
