Describe IPv6 multicast addressing options, media access control (MAC) address mappings, and multicast address scoping
Describe the dual-stacking approach to integrating IPv6 functionality into an existing IPv4-only environment
Describe tunneling mechanisms for IPv4-to-IPv6 transition, or for supporting IPv4 and IPv6 coexistence
