- A
No custom syslog message appears on the console or in the log buffer when the interface goes down.
The applet is designed to generate a syslog; its absence suggests the applet did not execute.
- B
The 'show event manager history events' output does not include an entry for the interface down event.
The history events command records triggered events; missing entry indicates the event was not processed by EEM.
- C
The 'show event manager policy active' output shows the applet with a non-zero 'fail count' field.
A non-zero fail count indicates that the applet attempted to execute but encountered an error, preventing successful completion.
- D
The interface goes down and the router generates a default syslog message like '%LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down'.
Why wrong: This is normal Cisco IOS behavior and does not indicate EEM failure; the applet is intended to run in addition to default logging.
- E
The 'show event manager environment' output shows the variable '_event_type' as 'none'.
Why wrong: The environment variables are set during applet execution; this output would not be visible if the applet failed, and 'none' is not a typical value for a triggered event.
Quick Answer
The answer is three specific symptoms: no custom syslog generated, the trigger event missing from 'show event manager history events', and a non-zero 'fail count' in 'show event manager policy active'. These symptoms directly indicate that the EEM applet failed to execute because a successful applet would produce the configured syslog, log the trigger event, and show a zero failure count. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to differentiate between a policy that is registered but malfunctioning versus one that never triggered—a common trap is assuming a policy listed in 'show event manager policy active' is working correctly. Remember, a non-zero fail count is the smoking gun; the history events will also be empty for that trigger, and no custom syslog will appear in the logs. For a memory tip, think "No log, no history, fail count not zero" to quickly recall the three failure indicators.
300-410 Embedded Event Manager (EEM) Practice Question
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.
Which THREE symptoms indicate that an Embedded Event Manager (EEM) applet configured to send a syslog message upon interface down has failed to execute? (Choose THREE.)
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
No custom syslog message appears on the console or in the log buffer when the interface goes down.
If the applet fails, no custom syslog is generated, the 'show event manager history events' will not show the trigger, and the 'show event manager policy active' may show the policy but with a non-zero failure count. The other options either describe normal behavior or unrelated issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

The interface goes down and the router generates a default syslog message like '%LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down'.
Why it's wrong here

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.
