Which of the following settings enables Nessus to detect when it is sending too many packets and the network pipe is approaching capacity?

Netstat WMI Scan is a setting that uses Windows Management Instrumentation to enumerate open ports and active connections on Windows hosts, and has no relation to detecting or managing network congestion caused by the scanner.

Silent Dependencies is a Nessus plugin behavior setting that suppresses execution of plugins whose prerequisite checks have not been satisfied, which is unrelated to controlling scan-induced network congestion.

'Consider unscanned ports as closed' instructs Nessus to treat any port not explicitly scanned as closed when evaluating plugin logic, and provides no mechanism for detecting or responding to network congestion.

This Nessus advanced scan setting enables the scanner to detect TCP congestion signals such as dropped packets or increased round-trip latency and dynamically reduce the number of concurrent connections being opened. By throttling parallel connections in response to congestion cues, Nessus prevents itself from saturating the network pipe and avoids causing false negatives or network disruptions during the scan.
