Which command displays the statistics for Ethernet network interfaces?

• A. ifconfig
• B. ifstat
• C. sysconfig
• D. sysstat

Answer: (B)

To see live statistics for Ethernet interfaces, you want a tool that reports per-interface data in real time. ifstat does exactly that by showing per-interface receive and transmit statistics (throughput, packets, errors, etc.) and updating at your chosen interval. This makes it the best fit for monitoring how much traffic each NIC is handling right now. Other options serve different purposes: ifconfig is mainly for configuring interfaces and can show basic status but not continuous per-second statistics; sysconfig handles system configuration; sysstat is a collection of tools for overall performance data (like iostat, sar) and isn’t focused on real-time per-interface traffic. So ifstat provides the targeted, ongoing Ethernet interface statistics you’re looking for.
