Which UDP port is used by DHCPv6 for server messages?

Explanation:
DHCPv6 uses UDP with distinct ports for client and server communication. Clients send from port 546 to the server on port 547, and the server replies back to the client (from 547 to 546). So, the server-side port involved in DHCPv6 server messages is 547 UDP. The other options either refer to the client port (546), or use TCP (DHCPv6 runs over UDP, not TCP).
