An organization plans to temporarily connect its IPv4 infrastructure to a new, IPv6-based service provider. Which of the following options facilitates communication between the new provider's IPv6 network and the organization's existing IPv4 system without altering client or server configurations?
NAT64 is the correct choice for transitioning from IPv4 to IPv6 by translating IPv6 addresses to IPv4 addresses and vice versa, allowing IPv4 clients to access IPv6 services transparently. Dual-stack architecture implies running both IPv4 and IPv6 on every device, which changes the set-up on clients. A Tunnel broker mainly creates a tunnel for IPv6 traffic over an IPv4 network, rather than facilitating communication between IPv4 clients and IPv6 services. DHCP relay is used to forward DHCP messages between clients and servers on different networks, but does not translate between IP versions.
