What two mechanisms are used by Dynamic ARP inspection to validate ARP packets for IP addresses that are dynamically assigned or IP addresses that are static? (Choose two.)

  • MAC-address-to-IP-address bindings
  • RARP
  • ARP ACLs
  • IP ACLs
  • Source Guard

Explanation: Two methods can be used by Dynamic ARP Inspection (DAI) to determine the validity of MAC-address-to-IP-address bindings. One is a bindings database built by DHCP snooping. The other method is through the use of user-configured ARP ACLs.
