- A
The router supports monitoring of configuration changes via SNMP.
CISCO-CONFIG-MAN-MIB provides objects to monitor configuration changes.
- B
The router does not support the IF-MIB.
Why wrong: IF-MIB is listed, so it is supported.
- C
The router only supports Cisco proprietary MIBs.
Why wrong: Standard MIBs like IF-MIB, SNMPv2-MIB, and IP-MIB are also supported.
- D
The ENTITY-MIB is used for entity authentication.
Why wrong: ENTITY-MIB provides information about physical entities (chassis, modules), not authentication.
Question 999 of 2,152
Show SNMP MIB — Identifying Supported MIBs
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.
A network engineer runs the following command on Router R1:
R1# show snmp mib
MIB: IF-MIB MIB: SNMPv2-MIB MIB: IP-MIB MIB: CISCO-CONFIG-MAN-MIB MIB: ENTITY-MIB
Based on this output, which statement is correct?
Quick Answer
The correct answer is that the router supports monitoring of configuration changes via SNMP, because the output of the show snmp mib command lists CISCO-CONFIG-MAN-MIB among the supported MIBs. This MIB specifically provides objects for tracking configuration events, such as when a running configuration is saved or modified, enabling SNMP-based configuration change monitoring. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to interpret which MIBs are loaded on a device and what functionality they imply; a common trap is to assume that any MIB listed, like IF-MIB or IP-MIB, indicates advanced features, but only the presence of CISCO-CONFIG-MAN-MIB directly confirms configuration management support. When you see show snmp mib supported MIBs output, focus on the vendor-specific MIBs for specialized capabilities. Memory tip: “CISCO-CONFIG-MAN” equals “change tracking,” so if you see it, think configuration monitoring.
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 router supports monitoring of configuration changes via SNMP.
The output of 'show snmp mib' lists the MIBs that the router supports. The presence of CISCO-CONFIG-MAN-MIB indicates that the router supports the Cisco Configuration Management MIB, which allows SNMP to monitor and manage configuration changes, such as when a configuration is saved or modified. Therefore, option A is correct.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 router supports monitoring of configuration changes via SNMP.
Why this is correct
CISCO-CONFIG-MAN-MIB provides objects to monitor configuration changes.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The router does not support the IF-MIB.
Why it's wrong here
IF-MIB is listed, so it is supported.
- ✗
The router only supports Cisco proprietary MIBs.
Why it's wrong here
Standard MIBs like IF-MIB, SNMPv2-MIB, and IP-MIB are also supported.
- ✗
The ENTITY-MIB is used for entity authentication.
Why it's wrong here
ENTITY-MIB provides information about physical entities (chassis, modules), not authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that 'show snmp mib' lists only Cisco proprietary MIBs, but the output includes standard MIBs like IF-MIB and SNMPv2-MIB, so candidates must recognize that both standard and proprietary MIBs can be supported.
Detailed technical explanation
How to think about this question
The CISCO-CONFIG-MAN-MIB (CISCO-CONFIG-MAN-MIB.my) provides objects for monitoring configuration events, such as ccmHistoryRunningLastChanged and ccmHistoryRunningLastSaved, which can trigger SNMP notifications (traps) when the running configuration is modified. In real-world scenarios, this MIB is critical for compliance and auditing, allowing NMS platforms like SolarWinds or PRTG to detect unauthorized configuration changes without relying on CLI logs.
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.
