Answer 1

The additional command required to enable DAI is 'ip arp inspection validate src-mac'.

Step-by-step explanation:

The command ip arp inspection vlan 11 is used to enable Address Resolution Protocol (ARP) inspection on VLAN 11. ARP inspection is a security feature that validates the source MAC address in ARP packets to prevent ARP spoofing attacks. To enable Dynamic ARP Inspection (DAI), you need to add the command ip arp inspection validate src-mac to the configuration.
