Options

• BLog files

Explanation

The question asks what ntop uses as its primary method for data collection.

Common mistakes.

• B. While ntop may produce log files, it does not primarily collect network data by reading system or application log files.
• C. Frame Relay is a wide area network (WAN) technology, not a data collection method that ntop directly uses for its input; ntop monitors traffic over interfaces, including those connected to WANs.
• D. SNMP (Simple Network Management Protocol) is used for querying network device statistics, but ntop's core functionality involves deep packet inspection, which is distinct from SNMP's summary data collection.
