300-410 Practice Question: Which THREE symptoms indicate that an Embedded…
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
No custom syslog message appears on the console or in the log buffer when the interface goes down.
Why this is correct
The applet is designed to generate a syslog; its absence suggests the applet did not execute.
- ✓
The 'show event manager history events' output does not include an entry for the interface down event.
Why this is correct
The history events command records triggered events; missing entry indicates the event was not processed by EEM.
- ✓
The 'show event manager policy active' output shows the applet with a non-zero 'fail count' field.
Why this is correct
A non-zero fail count indicates that the applet attempted to execute but encountered an error, preventing successful completion.
- ✗
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
This is normal Cisco IOS behavior and does not indicate EEM failure; the applet is intended to run in addition to default logging.
- ✗
The 'show event manager environment' output shows the variable '_event_type' as 'none'.
Why it's wrong here
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.
