B is the correct answer. “API-Based SDN implementation” D is a true statement but
the wrong answer to the question.
Answer is D
Where the Control and forwarding Plane is still in the legacy device not separated and management can be centralized
Based on JCF, there are 3 plans (or 4, with service plane on top of management plane)
Management Plane
Control Plane
Data Plane (or Forwarding Plane)
SDN via API only separate mgmt plane. So D is correct.
Correct answer is D not A nor B
Wrong. The controle plane still on the device itself. It only adds Management Plane, where the SDN Controller (via API) manages all devices.
Correct is D
DSN via API is the only one that does not separate control plane and forwarding plane and it still uses centralized management. The answer is A
