Which two of the following are advantages of Layer 2 Ethernet switches over hubs? (Choose two.)
A.
To increase the size of broadcast domains
B.
To filter frames according to MAC addresses
C.
To allow simultaneous frame transmissions
D.
To increase the maximum length of UTP cabling between devices
E.
decreasing the number of collision domains
F.
increasing the size of broadcast domains
Explanation:
A hub is a broadcast domain and a collision domain, while a switch is a broadcast domain, each interface is a collision domain. The switch is a device of data link layer, forwards and floods data frames based on the MAC address. The hub adopts the shared bandwidth working mode, while the switch adopts dedicated bandwidth.
