300-435 Question 105
Single answerYou are tasked with setting up network telemetry in an enterprise environment. The goal is to minimize bandwidth usage while ensuring telemetry data is available in near real-time for analysis. Which telemetry model is most suitable for this scenario?
- A
Pull-based telemetry model
- B
Push-based telemetry model
- C
SNMP polling model
- D
Syslog-based telemetry model
Show answer and explanation
Correct answer: B
Explanation
The push-based telemetry model is ideal for scenarios where near real-time data is required with minimal bandwidth usage. It enables devices to send updates only when relevant changes occur, rather than requiring periodic polling, making it efficient and scalable for modern enterprise environments.
- A. Incorrect.
A pull-based telemetry model requires the collector to request data periodically from devices. This can cause delays and unnecessary bandwidth usage, making it less suitable for near real-time data collection.
- B. Correct.
A push-based telemetry model allows devices to send data proactively to collectors when configured, minimizing latency and reducing unnecessary polling traffic, which aligns well with the scenario's requirements.
- C. Incorrect.
SNMP polling is similar to the pull-based model, where the network management system queries data from devices periodically. It is not efficient for near real-time telemetry and can consume more bandwidth.
- D. Incorrect.
Syslog is used for logging events and messages from devices but is not designed for structured telemetry data or near real-time updates. It is more suited for event logging rather than telemetry collection.
