Question

A network team currently logs into each of 200 switches individually via SSH to push identical VLAN and ACL changes, a process that takes hours and frequently introduces inconsistent configurations. Management asks for an approach that centralizes configuration intent and pushes it consistently across all devices from a single point. Which characteristic of controller-based networking best addresses this requirement compared to the traditional model?

Accepted Answer

A centralized control plane distributes consistent policy to all devices, reducing per-device manual configuration

Answer

Each device independently runs its own control plane, so changes must still be made box-by-box

Answer

The controller eliminates the need for any data plane on the physical switches

Answer

Spanning tree convergence is accelerated, which removes the need for centralized configuration
