300-410 Practice Question: The default SNMP trap queue length on Cisco IOS?
What is the default SNMP trap queue length on Cisco IOS?
⚠ Common exam trap
Cisco often tests the default SNMP trap queue length as a specific numeric value, and the trap here is that candidates confuse it with other default SNMP parameters (like the default SNMP community string or default SNMP version) or assume a larger value like 100 is the default due to common practice in production networks.

Correct answer & explanation
✓
10
The default SNMP trap queue length on Cisco IOS is 10. This value defines the maximum number of SNMP traps that can be queued in the trap buffer before they are sent to the configured SNMP trap receivers. If the queue is full and a new trap is generated, the oldest trap is dropped to make room for the new one.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
10
Why this is correct
Cisco IOS caps the SNMP trap queue at 10 traps by default; once full, newly generated traps are discarded until space frees. This default satisfies the question's constraint, which asks specifically for the out-of-the-box queue length rather than a configurable maximum.
- ✗
100
Why it's wrong here
The default SNMP trap queue length on Cisco IOS is 10, not 100. This option is tempting because 100 represents the maximum configurable value for the SNMP trap queue length using the `snmp-server trap-queue` command. While an administrator can manually configure the queue to 100, the question specifically asks for the *default* setting, making 10 the correct answer in that scenario.
- ✗
Unlimited
Why it's wrong here
Cisco IOS caps the SNMP trap queue at a fixed finite value, so traps are dropped once it fills rather than buffering indefinitely. Unlimited sounds appealing because it implies no trap loss during bursts, but no IOS release offers unbounded queueing; the queue is deliberately bounded to protect device memory.
- ✗
5
Why it's wrong here
The default trap queue holds 10 traps, not 5, so this understates the buffer and would mislead capacity planning for trap bursts. It is tempting because small round numbers feel like plausible IOS defaults, yet 5 matches no documented default for this queue.
