Answer: B
You should investigate the number of collisions to determine
if a customer should switch from a hub environment to a
switched environment. A collision domain is the network area
within which frames that have collided are propagated or
increased. Repeaters and hubs propagate collisions but
switches, bridges, and routers do not. By controlling
collisions, users have more available bandwidth and have
better response time.
