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.)
A. Use dual-stack lite from the MPLS network to the IGR.
B. Use IPv6 tunneling from the devices to the core MPLS network.
C. Use dual-stack lite from the devices to the core MPLS network.
D. Use NAT44/64 from the MPLS network to the IGR
E. Use NAT44/64 from the devices to the core MPLS network.
