CompTIA Linux+ XK0-006 (V8) Practice Question

An application server running Ubuntu 22.04 is experiencing random timeouts when it calls a backend service. CPU, memory, and disk I/O all look normal, but a packet capture shows bursts of TCP retransmissions. The administrator suspects packets are being dropped on the server's primary interface (eth0). Which built-in command will most quickly display live RX/TX error and dropped-packet counters for that interface so the hypothesis can be confirmed?

  • systemctl status NetworkManager.service

  • journalctl -k -f

  • ip -s link show eth0

  • ss -s
