A corporation's network administrator is seeking measures to defend the internal network against attacks that involve malicious interception or alteration of address resolution communications. The administrator is looking for a switch feature that inspects and verifies network packets associated with the resolution of network layer addresses to link layer addresses, against a trusted database before these packets are allowed to update the local cache. Which security mechanism should be enabled to provide this level of packet validation?
Port security
Enabling DHCP snooping
Applying Access Control Lists (ACLs)
Dynamic ARP inspection
