A water utility wants access ports to forward only traffic sourced from IP addresses learned via legitimate DHCP for that port. Which feature depends on the DHCP snooping binding table to enforce that?
Select an answer to reveal the explanation.
Short Explanation
IP Source Guard checks each packet’s source against the DHCP snooping guest list for that port. Spoofed IPs that never got a real lease get shown the door.
Full Explanation
IP Source Guard filters client traffic using the DHCP snooping binding table (optionally with static bindings) so only authorized source IP/MAC combinations leave the port. Without snooping bindings, IPSG cannot dynamically learn legitimate leases. NetFlow, MST names, and LLDP-MED do not enforce DHCP-derived source validity.
