300-435 Question 123
Select 3A network operations team has deployed model-driven telemetry (MDT) in their Cisco enterprise network to proactively monitor network performance. During a sudden increase in latency across the network, they need to identify the root cause quickly. What are the benefits of using telemetry data in this troubleshooting scenario?
- A
Telemetry data delivers near real-time insights into network performance, allowing the team to detect issues faster.
- B
Telemetry data provides detailed historical logs of configuration changes for better root cause analysis.
- C
Telemetry data minimizes the need for manual polling by streaming data continuously from network devices.
- D
Telemetry data provides a guaranteed resolution to network issues by automating configuration changes.
- E
Telemetry data enables correlation of metrics across multiple network devices for comprehensive analysis.
Show answer and explanation
Correct answers: A, C, E
Explanation
Telemetry data is highly beneficial in troubleshooting because it streams near real-time data, eliminating manual polling, and enables correlation of metrics across devices. These capabilities help network engineers quickly identify and address the root cause of performance issues. However, it does not inherently include historical logs or automate issue resolution, which require other tools and processes.
- A. Correct.
Telemetry data provides near real-time insights by streaming data directly from network devices, helping the team detect performance issues as they occur.
- B. Incorrect.
While telemetry provides operational data, it does not inherently include historical logs of configuration changes. This requires separate configuration management tools.
- C. Correct.
Telemetry eliminates the need for manual polling by streaming continuous data, making it a more efficient method for monitoring network performance.
- D. Incorrect.
Telemetry data itself does not automate configuration changes or guarantee issue resolution. It provides information that can be used for manual or automated troubleshooting.
- E. Correct.
Telemetry allows network operators to correlate metrics across multiple devices, which is essential for identifying root causes of issues affecting the network as a whole.
