300-435 Question 119
Select 3A network engineer is troubleshooting intermittent latency issues in a Cisco SD-WAN deployment. The engineer decides to use telemetry data for the investigation. Which benefits does telemetry data provide in this scenario?
- A
Provides real-time streaming of network performance metrics
- B
Enables proactive detection of network anomalies
- C
Offers detailed historical network configurations
- D
Reduces the need for manual polling of device statistics
- E
Automatically resolves network issues without human intervention
Show answer and explanation
Correct answers: A, B, D
Explanation
Telemetry data is a critical tool for troubleshooting because it provides real-time and proactive visibility into network performance. It eliminates the inefficiencies of traditional manual polling methods and helps engineers quickly identify and address issues. However, it does not include historical configurations or provide automated resolutions, making options 1, 2, and 4 the correct answers.
- A. Correct.
Telemetry data provides real-time streaming of performance metrics, allowing engineers to monitor the network in near real-time and capture issues as they occur.
- B. Correct.
Telemetry data enables proactive detection of anomalies by continuously monitoring the network and flagging deviations from normal behavior.
- C. Incorrect.
Telemetry data generally does not include historical network configurations. Instead, it focuses on live and recent performance metrics.
- D. Correct.
Telemetry reduces the need for manual polling by automatically sending data to monitoring systems, improving efficiency and scalability.
- E. Incorrect.
Telemetry data itself does not automatically resolve network issues. It is used for monitoring and analysis, while resolution still typically requires human intervention or automation scripts.
