Which statement accurately describes NetFlow data collection in NetFlow Traffic Analyzer?

• A. It collects NetFlow and sFlow data from devices
• B. It collects only SNMP data
• C. It collects only ICMP data
• D. It collects NetFlow but not sFlow

Answer: (A)

NetFlow Traffic Analyzer ingests flow-based telemetry to reveal how traffic moves across the network. It collects NetFlow data from routers and switches to show who is talking to whom, which applications are using bandwidth, and where traffic peaks occur. Many devices also support sFlow, and NetFlow Analyzer can ingest those samples as well, enabling visibility for devices that export sFlow instead of NetFlow. This combination—NetFlow data plus sFlow data from capable devices—best describes its data collection capability. SNMP provides device health and interface counters rather than detailed traffic flows, ICMP is just a basic reachability protocol, and limiting to NetFlow alone would miss environments where devices export only sFlow.
