Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
Which statement best compares a traditional device-by-device network with a controller-based network?
- Traditional networks have no control plane; controller-based networks add the first control plane
- Traditional networks require APIs, while controller-based networks can be managed only through console cables
- Controller-based networks eliminate forwarding tables from switches and routers
- Traditional networks distribute configuration across devices; controller-based networks centralize policy and expose abstractions for consistent automation
Traditional networks have no control plane; controller-based networks add the first control plane — Traditional routers and switches have control-plane functions.
Traditional networks require APIs, while controller-based networks can be managed only through console cables — The management comparison is reversed and both designs can support multiple access methods.
Controller-based networks eliminate forwarding tables from switches and routers — Managed devices still need forwarding state to move traffic.
Traditional networks distribute configuration across devices; controller-based networks centralize policy and expose abstractions for consistent automation — Correct. Controller-based designs centralize policy and intent while managed devices still perform forwarding; traditional designs are configured more directly per device.
