YANG-push telemetry data offers several benefits over traditional data collection methods such as SNMP polling. One significant advantage is that it uses less bandwidth because it sends updates only when there’s a change in subscribed data, rather than repeatedly polling all devices at regular intervals regardless of changes. This makes it more efficient and reduces unnecessary network traffic. Additionally, YANG-push telemetry scales better than SNMP because it can handle more frequent updates from a large number of devices without overwhelming the network or management systems. References := ( Automating Cisco Enterprise Solutions Official Cert Guide )

Being stateless means that each request from client to server must contain all of the information needed to understand and complete the request; there is no session state stored on the server. Implemented over HTTP indicates that REST APIs use standard web protocols for communication. References: Automating Cisco Enterprise Solutions Official Cert Guide
