Which statement is valid when enabling ARP protection features on an HPE Aruba Networking CX switch?

The correct answer is B. Configuring IP to MAC address bindings allows ARP protection for networks without a DHCP. ARP protection relies on validated IP-MAC bindings. When a DHCP server is not present, you can still use ARP protection by manually configuring static IP-to-MAC bindings on the switch. This allows ARP validation without depending on DHCP snooping or lease information.
