- A
The 'readonly' group can read all MIB objects because its read view is 'iso'.
The read view 'iso' typically includes the entire MIB tree, allowing read access to all objects.
- B
The 'admin' group requires only authentication, not encryption.
Why wrong: The security level 'authPriv' requires both authentication and privacy (encryption).
- C
The 'readonly' group can send SNMP traps.
Why wrong: The notify view is <none>, so no traps are sent for this group.
- D
Both groups have the same security level.
Why wrong: 'readonly' uses authNoPriv, while 'admin' uses authPriv.

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.
A network engineer runs the following command on Router R1:
R1# show snmp group
group name: readonly security model: v3 security level: authNoPriv context: <none> read view: iso write view: <none> notify view: <none>
Group name: admin security model: v3 security level: authPriv context: <none> read view: iso write view: iso notify view: iso
Based on this output, which statement is correct?
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 'readonly' group can read all MIB objects because its read view is 'iso'.
Option A is correct because the 'readonly' group has a read view set to 'iso', which corresponds to the entire ISO OID tree (1.3.6.1). This means the group can read all MIB objects accessible under that subtree, effectively granting full read access to all standard SNMP MIBs.
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 'readonly' group can read all MIB objects because its read view is 'iso'.
Why this is correct
The read view 'iso' typically includes the entire MIB tree, allowing read access to all objects.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The 'admin' group requires only authentication, not encryption.
Why it's wrong here
The security level 'authPriv' requires both authentication and privacy (encryption).
- ✗
The 'readonly' group can send SNMP traps.
Why it's wrong here
The notify view is <none>, so no traps are sent for this group.
- ✗
Both groups have the same security level.
Why it's wrong here
'readonly' uses authNoPriv, while 'admin' uses authPriv.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between security levels and view configurations, where candidates mistakenly assume 'authNoPriv' includes encryption or that a missing notify view still allows traps.
Detailed technical explanation
How to think about this question
In SNMPv3, the security level defines the combination of authentication and privacy: 'noAuthNoPriv' (none), 'authNoPriv' (authentication only), or 'authPriv' (both). The read, write, and notify views are configured using SNMP views that reference OID subtrees; setting a view to 'iso' (1.3.6.1) includes all standard MIB objects. A notify view of 'none' prevents the group from sending traps or informs, which is a common misconfiguration when troubleshooting SNMP notifications.
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.
