Which RESTCONF HTTP method corresponds to NETCONF `<edit-config>` operation="create"?

The correct answer is POST. In RESTCONF, the HTTP POST method is used to create new resources (data objects) within a collection. This directly maps to the NETCONF <edit-config operation="create" which is used to create new configuration elements. PUT is incorrect because, while it can create a resource if it doesn't exist, its primary use is to replace an existing resource or create a resource at a specified URI if it doesn't exist. It's more akin to NETCONF operation="replace" or operation="merge" when the target doesn't exist. CREATE is incorrect because it is not a standard HTTP method. GET is incorrect because it is used to retrieve (read) information, not to create it. This maps to NETCONF <get or <get-config.
