300-410 Practice Question: Which THREE commands can be used to verify the…
Which THREE commands can be used to verify the current NTP synchronization status and configuration on a Cisco IOS router? (Choose THREE.)
⚠ Common exam trap
Cisco often tests the distinction between commands that show NTP-specific details (like 'show ntp status' and 'show ntp associations') versus general clock commands (like 'show clock detail'), and includes a nonexistent command ('show ntp packets') to trap candidates who memorize command names without verifying their validity.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show ntp status
The 'show ntp status' command displays the NTP synchronization status, including whether the router is synchronized to an NTP server, the stratum level, and the reference clock ID. This directly verifies the current synchronization state of the NTP process on the Cisco IOS router.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show ntp status
Why this is correct
Correct. This command displays the NTP synchronization status, including whether the clock is synchronized, the stratum level, and the reference clock.
- ✓
show ntp associations
Why this is correct
Correct. This command shows all configured NTP associations (servers/peers), their reachability, delay, offset, and jitter.
- ✗
show ntp packets
Why it's wrong here
Incorrect. There is no 'show ntp packets' command in Cisco IOS. The correct command for packet statistics is 'show ntp statistics'.
- ✓
show ntp statistics
Why this is correct
Correct. This command displays NTP packet statistics, including packets sent, received, and dropped.
- ✗
show clock detail
Why it's wrong here
Incorrect. 'show clock detail' shows the calendar time and time source (e.g., user, NTP), but it does not provide the detailed NTP synchronization status or associations like the other commands.
