The answer is to use the 'show event manager statistics' command to identify which applets are triggered most often. This is the correct first step because high CPU due to EEM applet is almost always caused by syslog triggers firing too frequently, creating a feedback loop where each event spawns another event. By examining the statistics, you can pinpoint the specific applet that is consuming the most resources, allowing you to either refine its trigger condition or disable it entirely. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your ability to methodically isolate the root cause of performance degradation rather than jumping to a configuration change. A common trap is to immediately delete or modify applets without first gathering data, which can mask the underlying issue. Remember the memory tip: "Stats first, then axe the applet that maxes the stats."
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 is experiencing high CPU utilization. The engineer checks the process list and sees that the 'EEM Server' process is consuming a significant amount of CPU. The engineer reviews the EEM configuration and finds multiple applets that are triggered by syslog events. What should the engineer do first to reduce CPU utilization?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'show event manager statistics' command to see which applets are triggered most often.
High CPU from EEM is often due to excessive syslog triggers. The engineer should first identify which applets are being triggered most frequently and either optimize their conditions or reduce the number of applets.
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.
✗
Disable all EEM applets.
Why it's wrong here
Incorrect because this is too drastic; the engineer should first identify the problematic applet.
✓
Use the 'show event manager statistics' command to see which applets are triggered most often.
Why this is correct
Correct because this command provides per-applet trigger counts, helping pinpoint the culprit.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Increase the router's CPU priority for the EEM process.
Why it's wrong here
Incorrect because this does not address the root cause of excessive triggers.
✗
Change the syslog trigger to use a less frequent pattern.
Why it's wrong here
Incorrect because this is a guess without first identifying which applet is causing the issue.
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.
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.
