What network management tool monitors packet traffic and reports on sender, destination, and type of packet?

The network management tool that specifically monitors packet traffic and provides detailed reporting on aspects such as sender, destination, and type of packet is best represented by the concept of a network sniffer. A network sniffer captures and analyzes traffic that traverses a network, allowing administrators to inspect packet content and metadata in real-time or in offline analysis. This functionality is essential for diagnosing network issues, understanding network behavior, and improving overall security.

While a packet analyzer and a network scanner might seem similar, their primary functions differ. A packet analyzer focuses on dissecting packets for detailed examination but may not have the broader traffic monitoring capabilities of a network sniffer. A network scanner, on the other hand, is typically used to identify devices and services on a network, rather than deeply inspecting packet traffic.

A network management system (NMS) is a more comprehensive tool that may incorporate various functionality including monitoring, managing, and analyzing different facets of the network, but it does not exclusively focus on packet-level analysis like a network sniffer does. Thus, the correct choice effectively embodies the most specific tool for monitoring and reporting on packet traffic.
