CNX-001 · Question #82
A network engineer suspects high latency in traffic between edge routers and cloud gateways during business hours. Which tools or techniques should be used to validate the issue? (Choose two.)
The correct answer is A. NetFlow collector D. Latency heatmaps from monitoring tools. NetFlow (or sFlow/IPFIX) provides visibility into traffic flows, volume, and patterns. A collector can help correlate latency issues with traffic spikes or congestion during business hours. Monitoring platforms (e.g., ThousandEyes, SolarWinds, Datadog, or native cloud…

Explanation
NetFlow (or sFlow/IPFIX) provides visibility into traffic flows, volume, and patterns. A collector can help correlate latency issues with traffic spikes or congestion during business hours. Monitoring platforms (e.g., ThousandEyes, SolarWinds, Datadog, or native cloud monitoring tools) can generate latency heatmaps that visualize delay trends between sites and cloud gateways, making it easier to validate time-based issues.
