Which component of the SDN architecture automatically ensures that application traffic is routed according to policies established by network administrators?

Answer options

• A. SDN controller
• B. packet forwarding engine
• C. southbound API
• D. northbound API

Correct answer: A

The packet forwarding engine is responsible for the actual data transfer, while the southbound and northbound APIs are interfaces for communication between various components, but they do not enforce traffic routing policies.
