On Linux, which combination of commands provides the same information as Windows netstat -na and arp -a?

• A. netstat -natu and arp -a
• B. ifconfig -a
• C. ss -lptn
• D. lsof -i

Answer: (A)

To get the same kind of networking visibility on Linux as Windows netstat -na and arp -a, you’d use two commands: one to list all sockets and another to view the ARP table. The Linux equivalent for the socket view is netstat -natu. Here, -n shows numeric addresses, -a lists all sockets, and -t and -u cover TCP and UDP respectively, giving you a complete, numeric snapshot of open ports and connections similar to Windows netstat -na. For the ARP entries, arp -a prints the ARP cache just like Windows arp -a.

Other options don’t provide both pieces of information in one view. Ifconfig -a shows network interface configuration rather than the current socket state. ss -lptn can reveal listening sockets with process information but doesn’t include the full ARP table. lsof -i can list open network files and connections, but it doesn’t display ARP entries.
