Which of the following statements about Teredo traffic capture is true?

Explanation:
Teredo carries IPv6 traffic over IPv4 networks by wrapping IPv6 datagrams inside IPv4 UDP packets. The outer header is IPv4, the transport is UDP, and the inner payload is IPv6. It uses UDP port 3544 by default to carry this traffic, which is why traffic captures show IPv4/UDP packets on port 3544 with IPv6 data inside. This aligns with the described statement. The other ideas don’t match how Teredo operates: it’s IPv6 over IPv4, not IPv4 over IPv6, it uses UDP (not TCP), and it does rely on UDP at all.
