Which software collects traffic data, converts it into a usable format, and presents it via a web-based interface for monitoring network traffic?

• A. virus scanner
• B. DNSChanger
• C. API Monitor
• D. NetFlow Traffic Analyzer

Answer: (D)

NetFlow Traffic Analyzer focuses on monitoring network traffic by collecting flow records from routers and switches that support NetFlow. These devices export summarized traffic data—who talked to whom, what protocol, how much data, and when—rather than raw packets. The software gathers these flow records, converts them into usable metrics (throughput, top talkers, application usage, traffic trends), and presents everything through a web-based interface with dashboards and reports. This setup lets you monitor current usage, spot congestion, and plan capacity all in one place. The other options don’t fit this pattern: a virus scanner analyzes files on endpoints for malware, DNSChanger is a malware family that alters DNS settings, and API Monitor tracks software API calls rather than network traffic.
