HPE Aruba Certified Professional (ACP) – SD-WAN — Question 124

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?

Answer options

• A. IGMP snooping
• B. Dynamic IP lockdown
• C. DHCP reservations
• D. DHCP snooping

Correct answer: D

Explanation

The correct choice is D, DHCP snooping, as it helps validate DHCP messages and prevents rogue DHCP servers from distributing incorrect IP addresses. The other options do not directly address the issues arising from ARP protection and would not resolve the network access problems users are experiencing.
