- A
Disable syslog logging for interface state changes.
Why wrong: Incorrect because this would affect other monitoring; the issue is redundant EEM applets.
- B
Remove one of the duplicate EEM applets.
Correct because removing one applet eliminates the duplicate trap generation.
- C
Change the SNMP trap destination to a different host for one applet.
Why wrong: Incorrect because this would still send two traps to different hosts, not resolve the duplication.
- D
Increase the SNMP trap queue size.
Why wrong: Incorrect because this does not address the root cause of duplicate traps.

Resolving Duplicate SNMP Traps from EEM Applets
This 300-410 practice question tests your understanding of embedded event manager (eem). The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is troubleshooting a router that is sending duplicate SNMP traps for interface state changes. The engineer finds two EEM applets that both trigger on the same syslog pattern 'LINK-3-UPDOWN' and both send SNMP traps. What should the engineer do to resolve the duplicate traps?
Quick Answer
The answer is to remove one of the duplicate EEM applets. This resolves the issue because two separate Embedded Event Manager applets are both configured to trigger on the same syslog pattern, 'LINK-3-UPDOWN', and each independently sends an SNMP trap for the same interface state change, resulting in duplicate SNMP traps from the EEM applet. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your understanding of EEM applet configuration and event correlation—specifically that multiple applets reacting to the same event will each execute their action independently, leading to redundant notifications. A common trap is to overcomplicate the fix by adjusting SNMP timers or debounce intervals, but the direct solution is simply to eliminate the redundancy by removing one applet or merging them into a single, consolidated applet. Memory tip: "One event, one action—duplicate applets mean duplicate traps."
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
✓
Remove one of the duplicate EEM applets.
The duplicate traps are caused by two applets performing the same action. The engineer should remove one of the applets or combine them into one.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
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.
