Answer: C
Explanation:
A typical output of a NetFlow command line tool (nfdump in this case) when printing the stored flows may look as follows:
Date flow start Duration Proto Src IP Addr:Port Dst IP Addr:Port Packets Bytes Flows 2010-09-01 00:00:00.459 0.000 UDP 127.0.0.1:24920 -> 192.168.0.1:22126 1 46 1 2010-09-01 00:00:00.363 0.000 UDP 192.168.0.1:22126 -> 127.0.0.1:24920 1 80 1

The Sig ID field points to the IDS log – my guess
The samples output doesn’t match Net Flow v5, doesn’t include bytes or packets, Net flow doesn’t use the Severity field
The syslog field in the Severity field with the value 6 (perhaps Information) but doesn’t include Facility or the typical message
Answer should be A. IDS Log
