JNCIA-Cloud: Juniper Networks Certified Associate – Cloud (2021) — Question 12

Which statement is correct about SDN?

Answer options

• A. The SDN controller has a centralized view of the network.
• B. The SDN controller must provide a manual method for configuration.
• C. SDN simplifies the network by combining the control and forwarding planes into a single controller.
• D. The configuration and management of an SDN solution should be distributed to the edge of the network.

Correct answer: A

Explanation

Option A is correct because the SDN controller indeed provides a centralized view of the network, allowing for easier management and control. Options B and D are incorrect as they suggest manual configuration and distributed management, which contradict the principles of SDN that emphasize automation and centralization. Option C is misleading since it suggests a combination of planes, but does not highlight the centralized control aspect.
