Exhibit
Configured command: ntp server 192.0.2.20 Operations note: Authoritative NTP server = 192.0.2.200 Ping from router to 192.0.2.200 succeeds.
A router is configured as an NTP client, but its time never synchronizes. Based on the exhibit, what is the most likely issue?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
The router should use ntp master instead of ntp server.
ntp master is for acting as a time source, not for syncing to an external server.
B
Best answer
The configured NTP server IP is wrong.
The router points to 192.0.2.20 instead of 192.0.2.200.
C
Distractor review
NTP requires DHCP relay to function.
NTP does not depend on DHCP relay.
D
Distractor review
NTP can work only over TCP, not UDP.
NTP uses UDP, typically port 123.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this 200-301 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: The configured NTP server IP is wrong. — The device is pointed to the wrong NTP server address. Reachability matters for NTP, but the exhibit already tells you the intended server IP and shows a mismatch in configuration. Fixing the server address is the direct corrective step.
What should I do if I get this 200-301 question wrong?
Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
