A company has an external SDN application that works with an HP VAN SDN Controller. The application
programmer has tried testing several RESTful API calls but receives authentication errors. What does thenetwork administrator need to explain to the programmer?

A.
Every RESTful API call must include an X-Auth token. The token must be created by a valid certification
authority (CA) and installed on both the controller and external application in advance.

B.
Every RESTful API call must include a valid username and password. The only exception is when the
AuthRequired parameter is set to false in restful.сonf file.

C.
The application must be installed with a certificate that is signed by the same certification authority (CA)
that signed the VAN SDN Controller certificate.

D.
Every RESTful API call must include an X-Auth token. The token can be obtained by sending a call with
valid credentials to https://Controller_IP:8443/sdn/v2.0/auth.
