300-410 Practice Question: Which THREE symptoms indicate a problem with SNMP…
Which THREE symptoms indicate a problem with SNMP trap delivery from a Cisco router? (Choose THREE.)
⚠ Common exam trap
Cisco often tests the distinction between SNMP trap delivery issues and general SNMP or network problems, leading candidates to mistakenly select high CPU or ping success as relevant symptoms when they are not specific to trap delivery.
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 NMS does not receive traps, but other SNMP operations (gets) work.
SNMP traps are sent as unsolicited UDP packets from the router to the NMS, while SNMP get operations use a separate request-response mechanism. If gets succeed but traps fail, the issue is typically with trap configuration (e.g., wrong target IP, community string mismatch, or UDP port 162 blocked) rather than general SNMP or network connectivity.
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 NMS does not receive traps, but other SNMP operations (gets) work.
Why this is correct
Indicates a specific issue with trap generation or delivery, not general SNMP connectivity.
- ✓
The 'show snmp' command shows increasing 'SNMP queue overflow' counters.
Why this is correct
Indicates that the router is generating traps faster than they can be sent.
- ✓
Syslog messages show '%SNMP-3-AUTHFAIL' for the trap receiver.
Why this is correct
Authentication failures prevent traps from being accepted by the NMS.
- ✗
The router CPU utilization is consistently above 90%.
Why it's wrong here
High CPU can cause many issues, but is not a direct symptom of trap delivery problems.
- ✗
The NMS can ping the router successfully.
Why it's wrong here
Ping only verifies IP connectivity, not SNMP trap delivery.
