Question 120/151

A customer's environment includes hosts that support IPv6-only. Several of these hosts must communicate with a public web server that has only IPv4 domain name resolution. Which solution should the customer use in this environment?

A. utilize NAT64 to translate the addresses

B. Implement NAT44 at the edge of the customer network

C. use 6to4 and a tunnel to translate the addresses

D. implement 6PE to resolve hostname resolution

Correct Answer: A

NAT64 is a mechanism for IPv4-to-IPv6 transition and IPv4-IPv6 coexistence. Together with DNS64, the primary purpose of NAT64 is to allow an IPv6-only client to initiate communications to an IPv4-only server.NAT64 can also be used for IPv4-only clients initiating communications with IPv6-only servers using static or manual bindings.
