Explanation

Device Connector sits at the southbound position in network architecture because it communicates downward toward the physical infrastructure - the actual managed devices, hardware, or data plane elements below the controller/management layer.

  • Horizontal connector (A) is wrong because it operates east-west, connecting peer systems at the same layer rather than moving up or down the hierarchy.
  • Cloud connector (B) is wrong because it typically faces upward or outward toward cloud-based services and management platforms - a northbound or external direction.
  • Universal connector (D) is wrong because it implies generalized, multi-directional connectivity rather than a specific directional relationship in the control architecture.

Memory tip: Think of "south" as pointing down to the ground (devices, hardware, infrastructure) - the Device connector goes down to the devices, making it the southbound one. If it touches iron, it's southbound.
