- A
The syslog pattern 'LINK-3-UPDOWN' is incorrect; the correct pattern is 'LINK-5-CHANGED'.
Why wrong: Incorrect because 'LINK-3-UPDOWN' is a valid syslog message for interface state changes.
- B
The EEM applet is not registered with the SNMP agent.
Why wrong: Incorrect because EEM applets do not need to be registered with SNMP; they use the SNMP trap action directly.
- C
The SNMP trap action requires an SNMP community string to be specified in the applet.
Why wrong: Incorrect because the SNMP trap action uses the global SNMP configuration; however, the trap destination must be configured.
- D
The SNMP trap destination is not configured globally.
Correct because the EEM applet's SNMP trap action sends traps to the configured SNMP trap receivers; if none are configured, the trap is not sent.
Quick Answer
The answer is that the SNMP trap destination is not configured globally. This is the most likely cause because the EEM applet’s action snmp-trap command only triggers the sending of a trap, but it relies on the router having a pre-configured SNMP trap receiver—specifically, the snmp-server host command—to know where to send it. Without that global configuration, the router has no target IP address or community string to use, so the trap is generated internally but never transmitted. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding that EEM actions are not self-contained; they depend on underlying infrastructure like SNMP and syslog. A common trap here is assuming the applet alone handles delivery, when in fact you must verify both the event trigger (syslog generation) and the SNMP destination. Memory tip: “EEM fires the gun, but SNMP needs a target.”
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 not sending SNMP traps for a specific interface down event. The engineer has an EEM applet configured to send an SNMP trap when the interface goes down. The applet uses event syslog pattern 'LINK-3-UPDOWN' and action snmp-trap. The interface goes down, but no trap is sent. What is the most likely cause?

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 SNMP trap destination is not configured globally.
The EEM applet is triggered by a syslog message, but the syslog message may not be generated for that specific interface, or the SNMP trap action may require additional configuration such as an SNMP community or target host.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The syslog pattern 'LINK-3-UPDOWN' is incorrect; the correct pattern is 'LINK-5-CHANGED'.
Why it's wrong here
Incorrect because 'LINK-3-UPDOWN' is a valid syslog message for interface state changes.
- ✗
The EEM applet is not registered with the SNMP agent.
Why it's wrong here
Incorrect because EEM applets do not need to be registered with SNMP; they use the SNMP trap action directly.
- ✗

Why it's wrong here
Incorrect because the SNMP trap action uses the global SNMP configuration; however, the trap destination must be configured.
- ✓
The SNMP trap destination is not configured globally.
Why this is correct
Correct because the EEM applet's SNMP trap action sends traps to the configured SNMP trap receivers; if none are configured, the trap is not sent.
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.
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.
