300-445 Question 82
Single answerAn enterprise network operations team is tasked with implementing a network assurance solution to monitor and analyze network performance. They need to collect telemetry data from all network devices in real-time for anomaly detection and troubleshooting. Which data collection method should they implement to achieve this goal?
- A
SNMP polling with periodic intervals
- B
NetFlow for flow-based traffic monitoring
- C
Streaming telemetry using gRPC or NETCONF
- D
Syslog collection for logging device events
Show answer and explanation
Correct answer: C
Explanation
Streaming telemetry is a modern approach to data collection that allows for real-time monitoring by pushing data from network devices to a central collector without the need for periodic polling. This method is highly efficient, scalable, and ideal for enterprise network assurance use cases such as anomaly detection, troubleshooting, and performance analysis. Unlike SNMP polling or NetFlow, it provides continuous, granular telemetry data, making it the best choice for this scenario.
- A. Incorrect.
SNMP polling with periodic intervals is not ideal for real-time data collection because it relies on pulling data at predefined intervals, which may introduce delays and is less scalable for real-time anomaly detection.
- B. Incorrect.
NetFlow provides flow-based traffic data but does not provide continuous real-time telemetry at the granular level required for performance monitoring and troubleshooting.
- C. Correct.
Streaming telemetry using gRPC or NETCONF is the correct choice because it enables real-time, scalable, and high-frequency data collection directly from network devices, which is essential for anomaly detection and troubleshooting.
- D. Incorrect.
Syslog collection is useful for capturing log messages and event-based data, but it does not provide continuous performance metrics or real-time telemetry data.
