Which sequence ensures the router's time is synchronized with an external NTP server and verifies the current time?

• A. /system ntp client enable=yes; /system ntp client set primary-ntp=pool.ntp.org; /system clock print
• B. /system ntp client enable=no; /system clock print; /system ntp client set primary-ntp=pool.ntp.org
• C. /system ntp client enable=yes; /system clock print; /system ntp client set primary-ntp=pool.ntp.org
• D. /system ntp client enable=yes; /system clock print; /system ntp client set primary-ntp=pool.ntp.org

Answer: (B)

To keep the router’s time in sync with an external NTP server and verify it, you must first enable the NTP client so the device will contact NTP servers, then specify which NTP server to use, and finally print the clock to confirm the current time. If the NTP client is disabled, synchronization won’t happen at all. If you print the clock before configuring the server, you’ll just see the local or previous time, not the synchronized time. So the sequence that enables the client, sets the primary NTP server, and then checks the clock is the one that ensures synchronization and verification.
