Both dual-IP-layer and dual-stack architecture require IPv6-over-IPv4 tunneling to be effective as a transition mechanism.

Question

Quizplus · Accepted Answer

Dual-stack architecture does not require IPv6-over-IPv4 tunneling to be effective as a transition mechanism; it involves running IPv4 and IPv6 simultaneously on the same devices, allowing for direct communication over both protocols without the need for tunneling.
