Dynamic ARP Inspection (DAI) is a security feature that validates Address Resolution Protocol (ARP) packets in a network. DAI allows a network administrator to intercept, log, and discard ARP packets with invalid MAC address to IP address bindings.

Selected Answer: A
Untrusted Ports: ARP packets received on untrusted ports are subject to DAI inspection. DAI checks each ARP packet against the binding table to verify the source IP-MAC binding. If a packet fails the check, it is considered potentially malicious, and DAI can take actions to mitigate the threat.
