- A
The IP SLA operation is missing the 'ip sla reaction-configuration' command to trigger SNMP traps when the threshold is exceeded.
IP SLA traps require a reaction configuration that specifies the threshold and action (e.g., 'ip sla reaction-configuration 1 react timeout threshold 100 action trapOnly'). Without it, no traps are sent.
- B
The NMS is not configured to receive IP SLA traps.
Why wrong: The NMS receives all traps, but the router is not generating them.
- C
The SNMP community string is incorrect for trap sending.
Why wrong: The community string is configured globally, and the NMS can poll, so community is fine.
- D
The IP SLA operation is not scheduled correctly.
Why wrong: The operation shows 'Over threshold', so it is running and detecting threshold crossings.
Quick Answer
The answer is that the IP SLA operation is missing the `ip sla reaction-configuration` command to trigger SNMP traps when the threshold is exceeded. This is correct because while `snmp-server enable traps ip sla` globally enables trap generation for IP SLA, each individual operation must also be explicitly told which condition—such as a threshold crossing—should trigger a trap. Without the `reaction-configuration` command, the router knows the threshold has been crossed (as shown in `show ip sla statistics`), but it has no instruction to send a trap to the NMS. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your understanding of the two-part trap configuration: global enablement plus per-operation reaction. A common trap here is assuming the global command alone is sufficient. Remember the memory tip: “Global enables the gun, reaction pulls the trigger.”
300-410 SNMP Troubleshooting Practice Question
This 300-410 practice question tests your understanding of snmp troubleshooting. 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.
Router R8 is configured with SNMP and IP SLA. The IP SLA operation sends SNMP traps to the NMS when a threshold is crossed. The configuration includes: ip sla 1, icmp-echo 192.168.1.1, threshold 100, timeout 1000, frequency 10, ip sla schedule 1 life forever start-time now, snmp-server enable traps ip sla. However, the NMS receives no traps when the threshold is crossed. The IP SLA operation shows 'Over threshold' in show ip sla statistics. What is the root cause?
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
The IP SLA operation is missing the 'ip sla reaction-configuration' command to trigger SNMP traps when the threshold is exceeded.
IP SLA traps require the 'snmp-server enable traps ip sla' command, but also the IP SLA operation must be configured to send traps via the 'ip sla reaction-configuration' command. Without a reaction configuration, no traps are generated even if the threshold is crossed. The correct answer is: 'The IP SLA operation is missing the 'ip sla reaction-configuration' command to trigger SNMP traps when the threshold is exceeded.'
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 300-410 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.
