Selected Answer: D

D is correct - first there's basic authentication, then a token is used for follow-up interaction. https://www.cisco.com/c/en/us/td/docs/routers/csr1000/software/restapi/restapi/RESTAPIclient.html

On a second thought, C might be correct too - it describes the same mechanism, I would say C is "more correct" than D

C is the correct response. A post needs to be done to get the token, then it's added in the header To get this token, we need to send the basic auth.

D. From the book: "Authentication is accomplished using typical HTTP authentication models, such as basic authentication, where usernames and passwords are Base64 encoded and transmitted from the client to the server via an Authentication header"
