What is the function of the "netstat" command?

• A. To display network connections and listening ports
• B. To manage system updates
• C. To encrypt data transmissions
• D. To configure firewall settings

Answer: (A)

The "netstat" command is a network utility that provides a variety of information related to network connections, including active connections, listening ports, and various network statistics. When executed, it displays information about both inbound and outbound connections, along with the status of each connection (e.g., established, listening, closed). This makes it an essential tool for network troubleshooting and monitoring, allowing system administrators to assess the current state of the network and identify any potential issues. The other options provide functions that are not performed by the netstat command. Managing system updates typically involves using package management commands or system update tools, while encrypting data transmissions usually requires protocols or services like SSL/TLS. Configuring firewall settings generally involves commands specific to the firewall software or operating system being used. Therefore, the primary and correct function of the "netstat" command is to display network connections and listening ports.
