Refer to the exhibit. An engineer must connect the IPv6 island to the IPv4-only network to provide IPv6 hosts access to file servers and DNS services in the IPv4 network. Which NAT should the…

Stateless NAT66 is a mechanism for translating between IPv6 addresses (e.g., for renumbering), but it does not perform protocol translation between IPv6 and IPv4.

Stateful NAT66 is similar to stateless NAT66 in that it translates between IPv6 addresses and maintains state, but it does not perform protocol translation between IPv6 and IPv4.

Dynamic NAT-PT (Network Address Translation - Protocol Translation) is the correct choice to connect an IPv6 island to an IPv4-only network for outbound connections from IPv6 hosts to IPv4 services. It dynamically translates IPv6 source addresses to IPv4 source addresses from a pool on demand, allowing multiple IPv6 hosts to share a limited number of IPv4 addresses for accessing the IPv4 network.

Static NAT-PT provides a one-to-one, fixed mapping between an IPv6 address and an IPv4 address, which is inefficient and quickly exhausts IPv4 address space when many IPv6 hosts need to access IPv4 services, as each host would require a dedicated IPv4 address.
