The answer is that the EEM applet fails after reload due to the wrong event trigger, specifically because the applet runs before the router is fully booted. The event syslog pattern 'SYS-5-RESTART' fires too early in the boot sequence, before the router’s control plane and CLI parser are ready to accept configuration commands, causing the action cli command 'configure terminal' to silently fail. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your understanding of EEM event timing and the boot process—a common trap is assuming any syslog event is safe to use for post-reload automation. Instead, you should use 'event none' with a manual trigger or an 'event timer' with a sufficient delay to ensure the router is fully operational. Memory tip: think "SYS-5-RESTART is too early to start; delay the art of the CLI part."
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.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: Incorrect because EEM is enabled by default; the issue is with the trigger timing.
B
The syslog pattern 'SYS-5-RESTART' is misspelled.
Why wrong: Incorrect because the pattern is correct, but the timing of the event may be the issue.
C
The EEM applet runs before the router is fully booted, so the CLI commands fail.
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.
D
The EEM applet requires a 'event manager directory user' command to be configured.
Why wrong: Incorrect because that command is for specifying script directories, not for boot-time applets.
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.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
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.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Incorrect because that command is for specifying script directories, not for boot-time applets.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What is the correct answer to this question?
The correct answer is: 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.
