300-420 Exam Question 56
Refer to the exhibit.

An architect must design an IPv6 migration solution for an enterprise customer to support these requirements:
* Clients will transition to the new IPv6 network, which provides NAT64 and IPv6 DNS resolution services, using the same DNS name that points to the IPv4 address.
* The service provider will create a client-facing IPv6 interface with a new IPv6 virtual address that points to the same IPv4 DNS server.
* The service provider will support clients that use global IPv6 addresses and encapsulate IPv4 packets into IPv6 tunnels.
Which two migration solutions must the architect choose? (Choose two.)
