Which UDP port is used by DHCPv6 for client messages?

Explanation:
DHCPv6 relies on UDP, and the client messages originate from UDP port 546. The server listens on port 547, and communications between client and server involve the client sending from 546 to the server’s 547, with responses coming back from 547 to 546. So the port used by DHCPv6 client messages is 546 UDP. The other options aren’t correct because 547 UDP is the server’s destination port, not the client’s source port, and DHCPv6 uses UDP (not TCP), so TCP ports aren’t applicable.
