300-410 Practice Question: Is troubleshooting a router that fails to apply a…
A network engineer is troubleshooting a router that fails to apply a specific configuration change after a reload. The engineer has an EEM applet that runs at boot time to apply a set of commands. After a reload, the engineer checks the configuration and finds that the commands were not applied. The applet is configured with event syslog pattern 'SYS-5-RESTART' and action cli command 'configure terminal'. What is the most likely cause of the failure?
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 EEM applet runs before the router is fully booted, so the CLI commands fail.
The EEM applet uses the wrong event trigger. The 'SYS-5-RESTART' syslog message may not be generated or may be generated too early before the router is fully ready for configuration commands. The engineer should use 'event none' with a manual trigger or use 'event timer' to delay execution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The EEM applet is not enabled globally.
Why it's wrong here
Incorrect because EEM is enabled by default; the issue is with the trigger timing.
- ✗
The syslog pattern 'SYS-5-RESTART' is misspelled.
Why it's wrong here
Incorrect because the pattern is correct, but the timing of the event may be the issue.
- ✓
The EEM applet runs before the router is fully booted, so the CLI commands fail.
Why this is correct
Correct because the syslog message may be generated early in the boot process, and the router may not be ready to accept configuration commands at that point.
- ✗
The EEM applet requires a 'event manager directory user' command to be configured.
Why it's wrong here
Incorrect because that command is for specifying script directories, not for boot-time applets.
