Question 1

Explanation

Dynamic ARP inspection is an ingress security feature; it does not perform any egress checking.

Question 2

Explanation

Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.
