What command should you run to resume monitoring after stopping with CTRL+C during log viewing?

• A. restart the ns.log service
• B. tail -f ns.log
• C. tail -n 100 ns.log
• D. cat ns.log

Answer: (B)

Real-time log monitoring relies on following the file as it grows. The command tail -f ns.log continues to display new entries appended to the log, so after you press CTRL+C you can resume viewing updates by running tail -f ns.log again. The other options don’t provide ongoing updates: restarting the log service is a broader action that may affect logging itself rather than simply viewing the file; tail -n 100 shows only the last 100 lines and stops, not live updates; and cat ns.log prints the file once without following new content.
