D) The no ip arp inspection trust command is applied on all user host interfaces
A) DHCP snooping has not been enabled on all VLANs.
B) The ip arp inspection limit command is applied on all interfaces and is blocking the traffic of all users.

Suggested Answer: D

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.

I feel like B could be the issue. The limit command might be too strict.

I think it's option A. Without DHCP snooping, ARP packets get dropped.

Wait, how can all users lose communication just like that? Sounds weird!

No way, it has to be D) with that trust command messing things up.

I vaguely recall that if the trust command is not applied, it could cause issues. So maybe option D is the right answer?

I feel like I came across a similar question where enabling DAI on all VLANs was crucial. Could it be option C?

I’m not entirely sure, but I think if the ip arp inspection limit is set too low, it could block traffic. That might be option B?

I remember studying that Dynamic ARP Inspection relies on DHCP snooping to function properly, so maybe it's option A?
