Which IPv6 security feature blocks all traffic from an IPv6 host when initially connecting to a switch port except for traffic to gain an IPv6 address and discover IPv6 neighbors?
A is the right one, its literally the definition of ipv6 source guard. Its the only one that can block all traffic until the device IPV6 address its verified.
Should be C "Destination guard is a feature that works with IPv6 neighbor discovery to ensure that a device performs address resolution only for those addresses that are known to be active on the link.
It uses what is known as address glean functionality. Address gleaning involves snooping Neighbor Discovery Protocol (NDP) and DHCP messages on the link to populate the binding table. When a packet reaches the device and there is not yet an adjacency for the destination or for the next hop, the NDP consults the device binding table to verify that the destination or the next hop has been previously gleaned. If the destination is not found in the binding table, the packet is dropped. Otherwise, neighbor discovery resolution is performed."
