300-410 SNMP Troubleshooting Practice Question

This 300-410 practice question tests your understanding of snmp troubleshooting. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.

Router R10 is configured with SNMP and EEM. An EEM applet is configured to send an SNMP trap when a specific syslog message is generated. The applet uses the 'action snmp-trap' command. However, the NMS receives no trap. The syslog message is generated and logged. The router's show snmp statistics shows TrapsSent: 0. What is the root cause?

Question 1hardmultiple choice

Read the full network assurance explanation →

A
The EEM applet is configured to send a trap, but the 'snmp-server host' command is missing, so the router has no destination for the trap.
Without 'snmp-server host', the router does not know where to send the trap. The EEM action will fail silently.
B
The syslog message is not matching the EEM trigger pattern correctly.
Why wrong: The scenario states the syslog message is generated and logged, so the trigger should work.
C
The EEM applet is not registered due to a syntax error.
Why wrong: If there were a syntax error, the applet would not be registered, and the syslog would not trigger it. But the syslog is generated, so the applet is likely registered.
D
The SNMP community string is not configured with RW privileges.
Why wrong: Traps can be sent with RO community, but the host command is missing, so no destination.

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 is configured to send a trap, but the 'snmp-server host' command is missing, so the router has no destination for the trap.

EEM applets that send SNMP traps require the 'snmp-server enable traps' command to be enabled globally, and also the EEM applet must have the correct privilege level. Additionally, the 'action snmp-trap' command in EEM uses the SNMP community string configured globally. If the community string is not configured or the trap host is not set, the trap is not sent. The correct answer is: 'The EEM applet is configured to send a trap, but the 'snmp-server host' command is missing, so the router has no destination for the trap.'

Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Why this is correct
Without 'snmp-server host', the router does not know where to send the trap. The EEM action will fail silently.
Related concept
Authentication checks who the user is.
✗
The syslog message is not matching the EEM trigger pattern correctly.
Why it's wrong here
The scenario states the syslog message is generated and logged, so the trigger should work.
✗
The EEM applet is not registered due to a syntax error.
Why it's wrong here
If there were a syntax error, the applet would not be registered, and the syslog would not trigger it. But the syslog is generated, so the applet is likely registered.
✗
The SNMP community string is not configured with RW privileges.
Why it's wrong here
Traps can be sent with RO community, but the host command is missing, so no destination.

Common exam traps

Common exam trap: authentication is not authorization

Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.

Trap categories for this question

Command / output trap
Traps can be sent with RO community, but the host command is missing, so no destination.
Scenario analysis trap
The scenario states the syslog message is generated and logged, so the trigger should work.

Detailed technical explanation

How to think about this question

This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.

KKey Concepts to Remember

Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.

TExam Day Tips

Do not assume successful login means full administrative access.
Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
Separate login problems from permission problems before choosing the answer.

Key takeaway

Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

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 to study next

Got this wrong? Here's your next step.

Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related 300-410 questions on access control and AAA configuration.
