  Answers Explanation & Hints: The effect of entering the ip arp inspection vlan 10 configuration command on a switch is that it enables Dynamic ARP Inspection (DAI) on all switch interfaces in VLAN 10, which are previously configured with DHCP snooping. Dynamic ARP Inspection (DAI) is a security feature used to validate ARP packets in a network. It allows the switch to intercept and verify ARP packets before forwarding them. The ip arp inspection vlan 10 command enables DAI on all switch interfaces in VLAN 10 and ensures that only valid ARP packets are forwarded.
