Question 6
Which two features are foundations of a software-defined network instead of a traditional network? (Choose two.)
control plane and data plane are tightly coupled
build upon a robust software stack
requires device by device-level configurations
automated through expressed intent to a software controller
requires significant physical hardware resources
Correct answer: BD
Explanation:
In traditional networks, control plane and data plane are coupled tightly. It also requires device by device configurations and of course, it uses physical hardware resources to function. Whereas, SDN is based on a software stack. In Cisco SDNs are automated through expressed intent to a software controller.
