300-435 Question 106
Single answerYou are tasked with monitoring network devices in a Cisco ACI environment. The goal is to reduce bandwidth consumption and ensure only critical updates are sent to the telemetry system. Which telemetry model should you choose, and why?
- A
Pull-based telemetry model because it requests data on-demand from devices.
- B
Push-based telemetry model because it sends updates only when specific conditions are met.
- C
Pull-based telemetry model because it provides real-time monitoring with minimal overhead.
- D
Push-based telemetry model because it streams periodic updates to the telemetry system without being polled.
Show answer and explanation
Correct answer: B
Explanation
The push-based telemetry model is ideal in this scenario because it ensures only critical updates are sent based on pre-defined conditions or thresholds, reducing unnecessary bandwidth usage. Pull-based telemetry, on the other hand, relies on frequent polling, which increases overhead and does not align with the scenario's requirements.
- A. Incorrect.
Pull-based telemetry involves the telemetry system polling devices for data, which increases bandwidth consumption and does not meet the requirement to reduce overhead.
- B. Correct.
Push-based telemetry sends updates only when specific thresholds or conditions are met, aligning with the requirement to reduce bandwidth and prioritize critical updates.
- C. Incorrect.
Pull-based telemetry does not provide real-time monitoring and incurs significant overhead due to repetitive polling.
- D. Incorrect.
While push-based telemetry does stream periodic updates, this option does not emphasize the conditional updates required in the scenario.
