Which data collection methods are used by NetFlow Traffic Analyzer to monitor traffic data?

• A. NetFlow and sFlow
• B. SNMP traps and syslog
• C. SSH based metrics
• D. Email logs

Answer: (A)

NetFlow Traffic Analyzer gathers traffic data by importing flow records from routers and switches. Flow data provides detailed information about each conversation—source and destination IPs, ports, protocol, bytes, packets, and timing—so you can see who is talking to whom and how much data is moving. NetFlow is the traditional method that exports these records from network devices, while sFlow adds scalable visibility on very high-speed links by sampling packets and sending flow samples to the collector. Using both methods lets the analyzer produce accurate, scalable insights into bandwidth usage, top talkers, applications, and traffic patterns. SNMP traps and syslog are about device events and status, not per-flow traffic details; SSH-based metrics and email logs don’t deliver structured traffic flow data for monitoring.
