Which two types of data does Orion NetFlow Traffic Analyzer collect from network devices?

• A. NetFlow and sFlow
• B. SNMP traps and syslog
• C. NetFlow only
• D. IPFIX and NetFlow

Answer: (A)

Orion NetFlow Traffic Analyzer is built to ingest flow data from network devices, focusing on two formats that describe traffic flows: NetFlow data and sFlow data. NetFlow provides detailed per-flow information such as who talked to whom, which ports and protocols were used, and how much data was transmitted, giving precise visibility into traffic patterns. sFlow, on the other hand, uses sampling to capture packet information from many points in the network, offering scalable visibility in high‑speed environments. By supporting both NetFlow and sFlow, Orion NTA can analyze traffic from devices that implement Cisco NetFlow as well as those that use the more scalable, sampled sFlow approach. The other options involve event logs (SNMP traps and syslog) or only a single data type, or mention IPFIX as a separate category; the two data types specifically collected for flow analysis are NetFlow and sFlow.
