The automation engineer must replace device configuration using RESTCONF. How is this configured using the Python Library Requests?

The `delete()` method is used to remove an existing resource, not to replace it with new configuration.

The `post()` method is typically used to create a new resource or perform an action, rather than replacing an entire configuration.

The HTTP PUT method is used to entirely replace a resource at a specified URI; therefore, `put()` in the Requests library is the appropriate choice for replacing existing device configuration via RESTCONF.

The `patch()` method is used for partial updates to an existing resource, not for a complete replacement of the configuration.
