Actual exam question for Cisco's 300-420 exam

Question #: 109
Topic #: 8

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?

You know, if I were the architect, I'd be tempted to suggest a carrier-grade NAT solution just to see the customer's reaction. But that's probably not the best idea for this scenario.

I see your point, Rex, but I still think stateful NAT64 is the most suitable option for this specific requirement.

Ha! I bet the architect is wishing they had a crystal ball to see the future network needs. Better play it safe and go with the classic stateful NAT64.

I think dynamic NPTv6 could also work well in this situation.

I don't know, guys. Dynamic NAT-PT could give the customer more flexibility if they need to expand the network in the future. But I'm not sure if it's the best fit for this specific requirement.

I believe dynamic NPTv6 could also work, as it allows for prefix translation without changing the addresses.

Dynamic NPTv6 could work too, but it might be overkill for this scenario. The customer wants a simple one-to-one mapping, so static NAT-PT might be the most efficient choice.

Hmm, I think option A is the way to go. Stateful NAT64 seems like the most straightforward solution to connect the IPv6 hosts with the legacy IPv4 devices.
