Quick Answer
The answer is the `show ntp associations` command, which is the correct choice because it provides detailed NTP peer information including delay, offset, and jitter—the exact metrics needed for NTP synchronization monitoring. This command lists every configured NTP peer along with their current state, allowing you to analyze clock accuracy and stability by examining the offset (time difference) and jitter (variation in delay) between your Junos device and its time sources. On the JNCIA-Junos exam, this question tests your ability to recall the specific operational command for NTP troubleshooting, often appearing alongside traps like `show ntp status` (which shows local clock status but not peer details) or `show configuration system ntp` (which only displays configuration). A common memory tip is to remember that "associations" means relationships with other servers, so you need that word to see the peer-level metrics. Think of it this way: associations equals offset and jitter details.
This JNCIA-JUNOS practice question tests your understanding of operational monitoring and maintenance. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer needs to analyze NTP synchronization status and offset. Which command provides detailed NTP peer information including delay, offset, and jitter?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
show ntp statistics
Why wrong: Shows statistics but limited per-peer info.
show ntp associations
Displays peer address, delay, offset, jitter, and stratum.
show ntp status
Why wrong: Shows synchronization status but not per-peer details.
show ntp peer
Why wrong: Not a valid Junos command.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
show ntp associations
The 'show ntp associations' command displays detailed NTP peer information, including delay, offset, and jitter, which are essential for analyzing synchronization status. This command lists all configured NTP peers and their current state, providing the specific metrics needed to assess clock accuracy and stability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
show ntp statistics
Why it's wrong here
Shows statistics but limited per-peer info.
show ntp associations
Why this is correct
Displays peer address, delay, offset, jitter, and stratum.
Clue confirmation
The clue word "which command" in the question point toward this answer.

show ntp status
Why it's wrong here
Shows synchronization status but not per-peer details.
show ntp peer
Why it's wrong here
Not a valid Junos command.
Common exam traps
The trap here is that candidates familiar with Cisco IOS may expect 'show ntp peer' to work, but Junos uses 'show ntp associations' for the same detailed peer information, while 'show ntp peer' is not a valid command.
Trap categories for this question
Command / output trap
Shows statistics but limited per-peer info.
Detailed technical explanation
NTP uses a hierarchical stratum system, where each peer exchange includes timestamps for calculating round-trip delay and clock offset via the NTP algorithm (RFC 5905). Jitter is derived from the variance of offset samples over time, which 'show ntp associations' reports as 'dispersion' in Junos. In real-world scenarios, high jitter or delay can indicate network congestion or asymmetric paths, affecting synchronization accuracy.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the JNCIA-JUNOS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
