Which statement about the NPTv6 protocol is true?
A. It is used to translate IPv4 prefixes to IPv6 prefixes.
B. It is used to translate an IPv6 address prefix to another IPv6 prefix.
C. It is used to translate IPv6 prefixes to IPv4 subnets with appropriate masks.
D. It is used to translate IPv4 addresses to IPv6 link-local addresses.
Correct Answer: B

Explanation:
NPT stands for Network Prefix Translation.

IPv6-to-IPv6 Network Prefix Translation (NPTv6) performs a stateless, static translation of one IPv6 prefix to
another IPv6 prefix thereby allowing private Unique Local Addresses (ULA) to be able to access the Internet, by translating it to Global Routable Addresses

NPTv6 does not do a port translation, hence, the ports remain the same for incoming and outgoing packets.
