Correct answer: C, E

Explanation

The correct answers are C and E. Access control lists configured on each switch port can be used to filter ARP packets based on specific criteria, ensuring that only valid ARP traffic is allowed. Additionally, a DHCP binding database contains the IP-to-MAC address mappings that are essential for validating ARP requests, whereas the other options do not directly relate to ARP validation.
