Which of the following tools is used to analyze the files produced by several packet-capture programs such as tcpdump, WinDump, Wireshark, and EtherPeek?

tcptrace reads capture files in formats produced by tcpdump, WinDump, Wireshark, and EtherPeek and performs detailed TCP connection analysis including throughput, RTT, retransmissions, and window sizes - making it purpose-built for post-capture file analysis across those specific formats.

Nessus is a vulnerability assessment scanner that probes live systems for security weaknesses; it does not parse or analyze packet capture files.

OpenVAS is an open-source vulnerability scanner used to identify security issues in network infrastructure; it does not process or analyze packet capture file formats.

tcptraceroute is a traceroute variant that uses TCP SYN packets to trace network paths to a live host; it does not analyze pre-recorded packet capture files.
