Benefits of YANG-push Telemetry Data

BC.

YANG-push telemetry data is a mechanism for collecting and transmitting network telemetry data. Here are the benefits of YANG-push telemetry data over traditional data collection methods:

1. Precisely defined data subscriptions: YANG-push telemetry data allows for precise definition of data subscriptions, enabling the collection of specific data rather than entire sets of data. With traditional methods such as SNMP polls, the entire set of data is collected regardless of whether it is needed or not. This can result in a waste of network resources and an increase in processing overhead.

2. Scalability: YANG-push telemetry data is designed to scale better than SNMP, especially in large-scale network deployments. It uses a publish/subscribe model, where the data is pushed to subscribers, rather than the traditional polling model used by SNMP. This reduces the amount of network traffic and minimizes the processing overhead required to collect the data.

In contrast, SNMP polls each device on a network at a fixed interval, regardless of whether or not there has been a change in data. This can result in significant network overhead and processing power consumption, particularly in large-scale networks.

Therefore, options C and D are the correct answers, as they highlight the benefits of YANG-push telemetry data over traditional data collection methods. Option A is incorrect because it is not always true that subscription requests use less bandwidth than SNMP polls, it depends on the specific use case. Option B is incorrect because YANG-push telemetry data can use either UDP or TCP, and the choice of transport protocol depends on the specific use case. Option E is incorrect because SNMP is supported on more devices than YANG-push telemetry data, but this is changing as more devices begin to support YANG models.
