The command that the technician should use to determine which ports are being utilized for TCP listening on a Windows OS is "netstat."
Netstat (network statistics) is a command-line tool used for monitoring network connections and network statistics. It displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, and IPv4/IPv6 statistics.
To use the netstat command to determine which ports are being utilized for TCP listening, the technician can follow these steps:
Open the command prompt: Press the Windows key + R on your keyboard, type "cmd" in the Run box, and press Enter.
Type "netstat -an | find /i "listening"" and press Enter.
This command will display a list of all the ports that are currently in use and listening for incoming connections.
The "-an" option displays all active connections and listening ports. The "find /i "listening"" option filters the results to show only the ports that are currently listening.
Therefore, the correct answer is A. netstat.
