A company’s corporate policy has been updated to require that stateless, 1-to-1, and IPv6 to IPv6 translations at the Internet edge are performed.
What is the best solution to ensure compliance with this new policy?
A. NAT64
B. NAT44
C. NATv6
D. NPTv4
E. NPTv6

Correct Answer: E

Explanation:
NPTv6 provides a mechanism to translate the private internal organization prefixes to public globally reachable addresses. The translation mechanism is stateless and provides a 1:1 relationship between the internal addresses and external addresses. The use cases for NPTv6 outlined in the RFC include peering with partner networks, multi homing, and redundancy and load sharing.
