Show Suggested Answer

Suggested Answer: C

The DHCPv6 Guard feature blocks reply and advertisement messages that come from unauthorized

DHCP servers and relay agents.

Packets are classified into one of the three DHCP type messages. All client messages are always

switched regardless of device role. DHCP server messages are only processed further if the device role

is set to server. Further processing of server messages includes DHCP server advertisements (for

source validation and server preference) and DHCP server replies (for permitted prefixes).

If the device is configured as a DHCP server, all the messages need to be switched, regardless of the

device role configuration.
