Which mitigation technique would prevent rogue servers from providing false IPv6 configuration parameters to clients?

  • enabling DHCPv6 Guard
  • enabling RA Guard
  • implementing port security on edge ports
  • disabling CDP on edge ports

Explanation: DHCPv6 Guard is a feature designed to ensure that rogue DHCPv6 servers are not able to hand out addresses to clients, redirect client traffic, or starve out the DHCPv6 server and cause a DoS attack. DHCPv6 Guard requires a policy to be configured in DHCP Guard configuration mode, and DHCPv6 Guard is enabled on an interface-by-interface basis.
