When configuring IPv6 on an interface, which two IPv6 multicast groups are joined? (Choose two)
A . 2000::/3
B . 2002::5
C . FC00::/7
D . FF02::1
E . FF02::2
Answer: D E
Explanation:
When an interface is configured with IPv6 address, it automatically joins the all nodes (FF02::1) and solicited-node (FF02::1:FFxx:xxxx) multicast groups. The all-node group is used to communicate with all interfaces on the local link, and the solicited-nodes multicast group is required for link-layer address resolution. Routers also join a third multicast group, the all-routers group (FF02::2).
