View Answer

Answer: C

Explanation:

NetFlow provides a more efficient way of recording and analyzing network traffic patterns over an extended period of time compared to syslog messages, full packet capture, or firewall event logs. It collects metadata about traffic flows traversing the network devices which can be used for understanding normal baseline behavior as well as identifying anomalies.
