- A
The router has two SNMP communities: 'public' for read-only and 'private' for read-write access.
The output clearly shows 'public' with read-only and 'private' with read-write access.
- B
The router only allows SNMP writes with the 'public' community.
Why wrong: 'public' has read-only access, so writes are not allowed.
- C
The router is not configured for SNMP because no community strings are shown.
Why wrong: Two community strings are displayed, so SNMP is configured.
- D
The router uses SNMPv3 and these communities are for backward compatibility.
Why wrong: Community strings are used in SNMPv1/v2c, not SNMPv3.

300-410 SNMP Troubleshooting Practice Question
This 300-410 practice question tests your understanding of snmp troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 to troubleshoot SNMP access:
R1# show snmp community
Community name: public Community Index: public Storage-Type: nonvolatile Access: read-only View: v1default
Community name: private Community Index: private Storage-Type: nonvolatile Access: read-write View: v1default
What does this output indicate?

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 has two SNMP communities: 'public' for read-only and 'private' for read-write access.
The output shows two SNMP community strings configured on the router: 'public' with read-only access and 'private' with read-write access. This is a standard SNMPv1/v2c configuration where the community string acts as a password for access control, and the 'Access' field explicitly defines the permissions. Therefore, option A correctly interprets the output.
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 has two SNMP communities: 'public' for read-only and 'private' for read-write access.
Why this is correct
The output clearly shows 'public' with read-only and 'private' with read-write access.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The router only allows SNMP writes with the 'public' community.
Why it's wrong here
'public' has read-only access, so writes are not allowed.
- ✗
The router is not configured for SNMP because no community strings are shown.
Why it's wrong here
Two community strings are displayed, so SNMP is configured.
- ✗
The router uses SNMPv3 and these communities are for backward compatibility.
Why it's wrong here
Community strings are used in SNMPv1/v2c, not SNMPv3.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between SNMPv1/v2c community strings and SNMPv3 user-based security, so candidates may mistakenly assume that any community output implies SNMPv3 backward compatibility.
Detailed technical explanation
How to think about this question
In SNMPv1/v2c, the community string is transmitted in cleartext and matched against the configured strings for access control. The 'View' field (e.g., 'v1default') defines the MIB objects accessible to that community, which is typically the entire MIB tree by default. In real-world scenarios, using read-write communities like 'private' is a security risk, and best practices recommend using SNMPv3 with authentication and encryption or restricting access via ACLs.
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.
