Explanation

In an overlay software-defined networking (SDN) solution, overlay tunnels play a critical role in abstracting the underlying physical network (underlay) from the virtualized network (overlay). Option D: Overlay tunnels encapsulate traffic between endpoints (e.g., VMs, containers) and hide the complexity of the underlay network. This abstraction allows the overlay network to operate independently of the physical network topology, enabling flexibility and scalability.
