Exam 350-701 topic 1 question 134 discussion

SNMP polling can often be in the order of 5-10 minutes, CLIs are unstructured and prone to change which can often break scripts. The traditional use of the pull model, where the client requests data from the network does not scale when what you want is near real-time data. Moreover, in some use cases, there is the need to be notified only when some data changes, like interfaces status, protocol neighbors change etc. Model-Driven Telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics https://developer.cisco.com/docs/ios-xe/#!streaming-telemetry-quick-start-guide/streaming-telemetry

The benefit of using telemetry over SNMP to configure new routers for monitoring purposes is that telemetry uses a push method, which makes it faster than SNMP. SNMP (Simple Network Management Protocol) is a widely used protocol for network monitoring and management. SNMP uses a pull model where the management system sends a request to the device to retrieve information. The device responds to the request with the requested data. This can result in a delay between when a change occurs and when the monitoring system is made aware of it. Telemetry, on the other hand, uses a push model where the device sends data to the management system in near real-time. This makes telemetry faster than SNMP and can reduce the time between when a change occurs and when the monitoring system is made aware of it. Therefore, the answer is C: Telemetry uses a push method, which makes it faster than SNMP.

Pull model, such as SNMP, does not scale when what you want is near real-time data.
