300-410 Practice Question: Runs the following command to troubleshoot SNMP…
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?
⚠ Common exam trap
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.
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 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.
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 'show snmp community' output lists two configured community strings: 'public' mapped to read-only access and 'private' mapped to read-write access. Both use the default v1default view, so the distinction is purely the permitted operation level.
- ✗
The router only allows SNMP writes with the 'public' community.
Why it's wrong here
The output shows 'public' with read-only access and 'private' with read-write, so writes require the 'private' community, not 'public'. The option is tempting because 'public' is the first community listed, yet the Access line explicitly states read-only, contradicting any write capability.
- ✗
The router is not configured for SNMP because no community strings are shown.
Why it's wrong here
Two community strings are plainly displayed with their access levels, so SNMP is configured. The option is tempting because an empty output would indicate no SNMP configuration, but here 'public' and 'private' both exist, meaning the router is actively configured for SNMPv1/v2c access.
- ✗
The router uses SNMPv3 and these communities are for backward compatibility.
Why it's wrong here
The output lists SNMPv1/v2c community strings with Storage-Type nonvolatile; no SNMPv3 user, group or engineID information appears, so these are active v1/v2c credentials rather than compatibility entries. It is tempting because v3 coexistence is common, but v3 configuration would show under show snmp user.
