Which statement about TLS is true when using RESTCONF to write configurations on network devices?
- A. It is used for HTTP and HTTPS requests.
- B. It requires certificates for authentication.
- C. It is provided using NGINX acting as a proxy web server.
- D. It is not supported on Cisco devices.
Explanation: When a device boots up with the startup configuration, the nginx process will be running. NGINX is an internal webserver that acts as a proxy webserver. It provides Transport Layer Security (TLS)-based HTTPS. RESTCONF request sent via HTTPS is first received by the NGINX proxy web server, and the request is transferred to the confd web server for further syntax/semantics check.
