Show Suggested Answer

Suggested Answer: A

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.

The https-based protocol-RESTCONF (RFC 8040), which is a stateless protocol, uses secure HTTP

methods to provide CREATE, READ, UPDATE and DELETE (CRUD) operations on a conceptual

datastore containing YANG-defined data -> RESTCONF only uses HTTPs.
