The Certkiller .com network has 200 computers that are connected with hubs. An upgrade should
be suggested to improve network performance. Which of the following would be your choice?
A.
Wireless network adapters
B.
switches
C.
routers
D.
bridges
Explanation:
Hubs works without knowing what IP address is where, and therefore forwards all IP packets to all
ports except the receiving port. Switches builds a table over hosts on ports and sends directed IP
packets to single ports, unless the address does not exist in the table, then it will broadcast the
packet. This way switches reduce the size of the collision domains and therefore produces a more
efficient network.
