Which service on the router keeps time synchronized with external time sources?

• A. System Identity
• B. System Clock
• C. NTP Client
• D. System Backup

Answer: (C)

Timekeeping with external references is handled by the NTP Client. It talks to external time servers using the Network Time Protocol, compares the router’s local clock to the reference time, and adjusts the clock to reduce drift. This keeps timestamps in logs, certificates, and scheduled tasks accurate. The System Clock is just the on‑board time value and can drift if not regularly synchronized. The other options relate to names/identifiers or backups, not time synchronization.
