Default SNMP Inform Retransmission Timeout on Cisco IOS
This 300-410 practice question tests your understanding of snmp troubleshooting. 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.
What is the default retransmission timeout for SNMP informs on a Cisco IOS device?
Quick Answer
The answer is 30 seconds. This is the default SNMP inform retransmission timeout on Cisco IOS devices, meaning the agent will wait exactly 30 seconds for an SNMP Response message after sending an inform before it retransmits the inform request. This timeout is defined by the SNMP engine to ensure reliable delivery of informs—unlike traps, informs require acknowledgment, so the agent must wait a specified period for that acknowledgment before attempting a resend. On the Cisco CCNP ENARSI 300-410 exam, this value tests your understanding of SNMP reliability mechanisms and is often contrasted with the default timeout for SNMP gets or sets, which is typically 5 seconds. A common trap is confusing the inform timeout with the get/set timeout, so remember that informs use a longer window because they are event-driven and must account for network delays in delivering critical notifications. To lock it in, think: "Informs wait thirty—traps are dirty."

Correct answer & explanation
✓
30 seconds
The default retransmission timeout for SNMP informs on Cisco IOS devices is 30 seconds, as specified by the Cisco SNMP configuration. This timeout controls how long the device waits for an acknowledgment (inform response) before retransmitting the inform request. Option B is correct because Cisco IOS uses a default timeout of 30 seconds for inform operations, which is distinct from the 5-second default for SNMP get/set requests.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

60 seconds
Why it's wrong here
60 seconds is not the default; it can be configured but is not default.
- ✗
10 seconds
Why it's wrong here
10 seconds is not the default; the default is 30 seconds.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between default timeouts for SNMP informs (30 seconds) versus SNMP get/set requests (5 seconds), leading candidates to mistakenly choose 5 seconds.
Detailed technical explanation
How to think about this question
SNMP informs are confirmed notifications that require an acknowledgment from the NMS, unlike unconfirmed traps. The retransmission timeout is governed by the 'snmp-server inform' command's timeout parameter, defaulting to 30 seconds, and the device will retry up to three times by default (controlled by the 'retries' option). In real-world scenarios, if the NMS is slow or the network has high latency, increasing the timeout beyond 30 seconds can prevent unnecessary retransmissions and reduce network overhead.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
