Which two functions are completely independent when implementing NAT64 over NAT-PT? (Choose two.)
A. DNS
B. NAT
C. port redirection
D. stateless translation
E. session handling

Correct Answer: AB

Explanation:
Work Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication between IPv6-only and IPv4-only hosts and networks (whether in a transit, an access, or an edge network). This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneously handling IPv4 address depletion. The DnS64 and NAT64 functions are completely separated, which is essential to the superiority of NAT64 over NAT-PT.
