Question
An architect is designing a network solution for a customer. The network is IPv6-only with 1000 hosts. The design must provide external access to up to 10 concurrent IPv6 hosts to allow communication with legacy IPv4 devices on an adjacent network. The customer set aside 10 IPv4 addresses to allow for one-to-one communication between hosts. Which solution must the architect select?
Options
- Astatic NAT-PT
- Bdynamic NPTv6

Explanation
Stateful NAT64 is the appropriate solution in an IPv6-only network to allow IPv6 hosts to communicate with IPv4 devices. It provides translation between IPv6 and IPv4 addresses, enabling seamless communication. The "stateful" aspect of NAT64 allows multiple IPv6 hosts to share a limited pool of IPv4 addresses (in this case, 10 IPv4 addresses), which matches the customer's requirement of supporting up to 10 concurrent IPv6 hosts for external communication. This ensures efficient use of the allocated IPv4 addresses while maintaining compatibility with the legacy IPv4 network.
