What are two features of stateful NAT64? (Choose two.)

Stateful NAT64 typically implements Network Address Port Translation (NAPT64), which involves address overloading. This allows many IPv6 private addresses to share a smaller pool of IPv4 public addresses by using different source port numbers.

Due to address overloading, stateful NAT64 provides 1:N translations, meaning one IPv4 address can be used by multiple IPv6 endpoints simultaneously, thus supporting a large number of endpoints even with a limited IPv4 address pool.

While IPv6-translatable IPv6 address assignments (using prefixes like `64:ff9b::/96`) are a fundamental part of the NAT64 architecture for IPv6 hosts to reach IPv4 destinations, this is more of an addressing prerequisite for the IPv6 clients and destination mapping, rather than a direct feature of the stateful translation process itself.

Stateful NAT64 does not dictate how IPv6 hosts obtain their addresses; hosts can use SLAAC, DHCPv6, or manual configuration independently of the NAT64 mechanism.

Stateful NAT64 primarily provides 1:N translations (overloading) to conserve IPv4 addresses. 1:1 translation is characteristic of stateless NAT64 or basic stateful NAT without overloading, which is not the common or primary feature of stateful NAT64 deployments.
