This 200-301 practice question tests your understanding of ai and network operations. 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.
Exhibit
R1#show running-config | include ntp|logging
ntp server 203.0.113.5
logging host 192.0.2.20

R1#show ntp status

R1#show ip interface brief | include Loopback0
Loopback0 10.0.0.1 YES manual up up
R1#
You are connected to R1. Configure NTP client so that R1 synchronizes with the NTP server at 198.51.100.10, using its Loopback0 (10.0.0.1/32) as the source interface. Also configure syslog to send messages of severity 5 (notifications) and above to 192.0.2.20. The current configuration shows a misconfigured NTP server address and an incorrect logging trap level. Verify with 'show ntp status' (stratum should not be 16) and 'show logging'.

A
ntp server 198.51.100.10 source Loopback0
logging trap notifications
This correctly sets the NTP server to 198.51.100.10 with Loopback0 as the source interface, and sets the syslog trap level to notifications (severity 5), which sends messages of severity 5 and above.
B
ntp server 198.51.100.10 source Loopback0
logging trap 4
Why wrong: This is incorrect because 'logging trap 5' uses the numeric severity level, but the question expects the keyword 'notifications' for severity 5. While both are technically valid, the question specifies 'severity 5 (notifications)', and the correct answer uses the keyword.
C
ntp server 198.51.100.10
logging trap notifications
Why wrong: This is incorrect because it omits the 'source Loopback0' parameter. Without specifying the source interface, the NTP client will use the outgoing interface IP, which may not be Loopback0, potentially causing reachability or authentication issues.
D
ntp server 203.0.113.5 source Loopback0
logging trap 7
Why wrong: This is incorrect because it uses the wrong NTP server address (203.0.113.5 instead of 198.51.100.10) and sets the logging trap level to debugging (7), which sends all messages instead of only notifications (5) and above.

Correct answer & explanation
✓
ntp server 198.51.100.10 source Loopback0
logging trap notifications
The misconfigured NTP server address (203.0.113.5) and the debug-level logging trap (7) must be corrected to meet requirements. The correct commands are 'ntp server 198.51.100.10 source Loopback0' to use the specified server and Loopback0 as source, and 'logging trap notifications' (severity 5) to send only notifications and more severe messages. Option B is wrong because 'logging trap 4' sets the trap level to warning, which would not forward notifications. Option C misses the source interface, and Option D uses the wrong NTP server and an overly verbose trap level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

This is incorrect because 'logging trap 5' uses the numeric severity level, but the question expects the keyword 'notifications' for severity 5. While both are technically valid, the question specifies 'severity 5 (notifications)', and the correct answer uses the keyword.

This is incorrect because it uses the wrong NTP server address (203.0.113.5 instead of 198.51.100.10) and sets the logging trap level to debugging (7), which sends all messages instead of only notifications (5) and above.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓ntp server 198.51.100.10 source Loopback0
logging trap notificationsCorrect answer▾
Why this is correct
This correctly sets the NTP server to 198.51.100.10 with Loopback0 as the source interface, and sets the syslog trap level to notifications (severity 5), which sends messages of severity 5 and above.
✗ntp server 198.51.100.10 source Loopback0
logging trap 4Wrong answer — click to see why▾
Why this is wrong here
logging trap 4 sets the trap level to warning (severity 4), missing severity 5 notifications, so it fails to send messages of severity 5 and above.
Why candidates choose this
Candidates might think that using the numeric value is acceptable, but the question explicitly mentions the keyword, so the answer using the keyword is more precise.
✗ntp server 198.51.100.10
logging trap notificationsWrong answer — click to see why▾
Why this is wrong here
The NTP source interface must be explicitly configured to use Loopback0; otherwise, the NTP packets will use the IP of the egress interface.
Why candidates choose this
Candidates may forget to specify the source interface, especially if they assume the router will automatically use the loopback interface.
✗ntp server 203.0.113.5 source Loopback0
logging trap 7Wrong answer — click to see why▾
Why this is wrong here
The NTP server address is incorrect, and the logging trap level is set to debugging (7), which is too permissive and does not match the requirement of severity 5 (notifications).
Why candidates choose this
This option reflects the misconfigured state mentioned in the question, so candidates might think it is the correct fix, but it actually perpetuates the errors.

Common exam traps
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.
Trap categories for this question
Keyword trap
This is incorrect because 'logging trap 5' uses the numeric severity level, but the question expects the keyword 'notifications' for severity 5. While both are technically valid, the question specifies 'severity 5 (notifications)', and the correct answer uses the keyword.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-301 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.
