A. B. C. D.B
The correct answer is B. tcpdump.
When using the "monitor traffic" command on Junos devices, the device captures packets on the specified interface and then displays them on the console. The captured packets can be filtered using various options, such as source or destination IP address, port number, protocol, and so on.
The "monitor traffic" command uses the tcpdump utility, which is a powerful command-line tool used to capture and analyze network traffic. Tcpdump runs on most Unix-based operating systems, including Linux, macOS, and Junos.
Tcpdump works by capturing packets from a network interface and then displaying them on the console or saving them to a file. The captured packets can be filtered using various options, such as port number, protocol, source or destination IP address, and so on.
When the "monitor traffic" command is executed on a Junos device, tcpdump is invoked with the appropriate options to capture the specified traffic on the specified interface. The captured packets are then displayed on the console in real-time.
In summary, the "monitor traffic" command on Junos devices uses the tcpdump utility to capture and display network traffic on the console.
