Which command provides basic information about network connections?

• A. ifstat -a
• B. netdiag -n
• C. netstat -i
• D. sysstat 1

Answer: (C)

Focusing on the basics of how network interfaces are doing, netstat with the -i option provides a concise snapshot of each interface and its traffic counters. This shows per-interface statistics like RX and TX packets and any errors or drops, giving you the essential view of how connections are established and performing at the interface level. The other options serve different purposes: one would display real-time bandwidth usage per interface, another runs diagnostics, and the last isn’t a valid or relevant command here. So, netstat -i is the straightforward way to obtain basic information about network connections.
