C. A Service Token has been submitted to the controller via the Token field in RSDoc.
D. An Auth Token has not been submitted to the controller via the Token field in RSDoc.
Correct Answer: D
Explanation/Reference:
Explanation: This is an AuthenticationException.
Note: The SDN controller relies on token-based authentication to authenticate its REST APIs. In other words, all REST APIs except the /auth and /rsdoc APIs require an authentication token embedded in an "X-Auth-Token" header to be included with each REST request. The /auth API allows you to obtain a token, while the /rsdoc API provides live REST API documentation information about the controller’s REST API.
