Question

Which mitigation technique would prevent rogue servers from providing false ip configuration parameters to clients?

Answer 1

The answer is DHCP snooping

DHCP snooping acts like a firewall between DHCP servers and untrusted hosts. It differentiates untrusted interfaces connected to the end user and trusted interfaces connected to a switch or DHCP.
