HPE7-A08 · Question #23

You recently enabled ARP protection on your CX switches, but many users now complain that they can no longer access the network. What do you need to configure to resolve the issue?

The correct answer is C. DHCP snooping. Enabling DHCP snooping allows the switch to validate ARP messages against trusted DHCP bindings, preventing legitimate users from being blocked by ARP protection while maintaining network security.
