An IPv6-enabled router interface joins the all-nodes multicast group FF02::1 and the all-routers multicast group FF02::2. FF02::1 is used to reach all IPv6 nodes on the local link. FF02::2 is used to reach IPv6 routers on the local link. The interface also joins a solicited-node multicast group derived from its IPv6 address, but that specific group is not one of the answer choices. 2000::/3 represents global unicast space, FC00::/7 is unique local addressing, and 2002::/5 or similar values are not the required local multicast groups. The "FF" prefix is the key sign that the address is multicast, while the "02" scope means link-local scope. CCNA 200- 301 v1.1 Network Fundamentals expects candidates to identify common IPv6 address types and multicast groups used by Neighbor Discovery and routing functions. Therefore the verified answers are D and E. Reference: Cisco IPv6 multicast addressing and IPv6 interface behavior.
