300-420 Question 302
Single answerAn enterprise network has recently implemented model-driven telemetry for network monitoring. The network engineer reports reduced delays in troubleshooting and improved anomaly detection. What is one key reason why model-driven telemetry has this impact on the network?
- A
It uses a subscription-based model to push real-time data from the network devices to collectors.
- B
It relies on SNMP polling to retrieve data periodically from network devices.
- C
It reduces the need for network engineers to configure devices manually.
- D
It replaces all traditional monitoring protocols with a single unified protocol.
Show answer and explanation
Correct answer: A
Explanation
Model-driven telemetry leverages a subscription-based model to push real-time data from network devices to external collectors. This reduces delays associated with periodic polling methods (such as SNMP) and ensures that anomalies and issues are detected more efficiently. By streaming telemetry data continuously, it enables quicker troubleshooting and better decision-making in enterprise networks.
- A. Correct.
Model-driven telemetry uses a subscription-based model where real-time data is pushed from devices to collectors, enabling faster and more efficient monitoring.
- B. Incorrect.
SNMP polling is not a part of model-driven telemetry. SNMP relies on periodic polling, which can introduce delays and is less efficient compared to telemetry's real-time capabilities.
- C. Incorrect.
While model-driven telemetry improves network visibility, it does not directly eliminate the need for manual configurations by engineers.
- D. Incorrect.
Model-driven telemetry does not replace all traditional protocols but rather complements existing methods to provide enhanced real-time data collection.
