- A
Configure 'event snmp oid 1.3.6.1.4.1.9.9.117.1.1.2.1.1 get-type exact' within the applet.
This defines the SNMP event trigger, specifying the OID to monitor and the type of access (exact match) that will fire the applet.
- B
Ensure the 'snmp-server enable traps' command is configured globally.
SNMP must be enabled on the device for the EEM SNMP detector to function; otherwise, the event will not be recognized.
- C
Configure 'event syslog pattern "SNMP"' to capture the SNMP poll.
Why wrong: This would trigger on a syslog message containing 'SNMP', not on an actual SNMP OID poll; it is not the correct way to monitor OID polling.
- D
Configure an SNMP community string with read-write access inside the applet using 'action snmp-community'.
Why wrong: EEM does not require an SNMP community within the applet; SNMP communities are configured globally and are not part of EEM applet configuration.
- E
Configure 'event cli command "snmpwalk" sync yes' to trigger on SNMP walks.
Why wrong: This would trigger on a CLI command 'snmpwalk' being entered, not on an actual SNMP OID poll; it is a different event type.
Quick Answer
The answer is to ensure the 'snmp-server enable traps' command is configured globally. This is required because an EEM applet triggered by an SNMP OID poll relies on the device’s SNMP agent being active and authorized to send notifications; without this global command, the trap generated by the applet’s action will never be transmitted. The second step is configuring the 'event snmp oid' command within the applet itself, which defines the specific OID that, when polled, fires the event. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding of EEM event detectors and the prerequisite SNMP infrastructure—a common trap is confusing the applet’s event trigger with unrelated commands like 'event syslog' or 'event cli'. Remember the memory tip: “Enable traps first, then event the OID”—the global SNMP trap enable is the foundation, and the OID event is the trigger.
300-410 Embedded Event Manager (EEM) Practice Question
This 300-410 practice question tests your understanding of embedded event manager (eem). This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO configuration steps are required to enable an Embedded Event Manager (EEM) applet that sends an SNMP trap when a specific OID is polled? (Choose TWO.)
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
Configure 'event snmp oid 1.3.6.1.4.1.9.9.117.1.1.2.1.1 get-type exact' within the applet.
To trigger an EEM applet on an SNMP OID poll, you must configure the 'event snmp oid' command and ensure SNMP is enabled globally. The other options are either unnecessary (like configuring a community for the applet itself) or incorrect (like using 'event syslog' or 'event cli').
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.
- ✓
Configure 'event snmp oid 1.3.6.1.4.1.9.9.117.1.1.2.1.1 get-type exact' within the applet.
- ✓
Ensure the 'snmp-server enable traps' command is configured globally.
- ✗
Configure 'event syslog pattern "SNMP"' to capture the SNMP poll.
- ✗
Configure an SNMP community string with read-write access inside the applet using 'action snmp-community'.
Why it's wrong here
EEM does not require an SNMP community within the applet; SNMP communities are configured globally and are not part of EEM applet configuration.
- ✗
Configure 'event cli command "snmpwalk" sync yes' to trigger on SNMP walks.
Why it's wrong here
This would trigger on a CLI command 'snmpwalk' being entered, not on an actual SNMP OID poll; it is a different event type.
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.

Command / output trap
This would trigger on a CLI command 'snmpwalk' being entered, not on an actual SNMP OID poll; it is a different event type.
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.
