CCIE Data Center (legacy) — Question 41

Which two statements about the Cisco Open SDN Controller are true? (Choose two.)

Answer options

• A. It is a commercial distribution based on the OpenFlow controller.
• B. Your own, new network service functions can be added via Java APIs.
• C. Security is enforced by using the Open Services Gateway Initiative framework.
• D. It can be used in multivendor environments.
• E. The controller is available as an appliance only.

Correct answer: A, B

Explanation

Options A and B are correct because the Cisco Open SDN Controller is indeed a commercial version based on the OpenFlow controller and allows the addition of new network service functions via Java APIs. Options C and E are incorrect as security is not solely managed by the OSGI framework, and the controller is not limited to being available only as an appliance; it can also be deployed in other forms. Option D, while plausible, does not specifically represent a true statement about the controller's capabilities.
