Give 3 reasons to use a proxy.

• Switch → Selects port based on MAC address; floods only for broadcast, unknown unicast, and default multicast.

• Hub → Floods all traffic to all ports.

• Router → Uses IP destination address for forwarding, not MAC-based flooding.

• Modem → Connects LAN to WAN, not a switching device.
