Question 26/49
A network administrator configures Dynamic ARP Inspection on a switch. After Dynamic ARP Inspection is applied, all users on that switch are unable to communicate with any destination. The network administrator checks the interface status of all interfaces, and there is no err-disabled interface. What is causing this problem?

Answer is B. DIA uses DHCP snooping or an ARP ACL to perform inspection. no ip arp inspection trust command will only make a port untrusted. By default all the ports are untrusted when DIA is configured. As no port is in the err disabled state, it means there has been no DIA violation or no rate limit violation.
