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 output clearly shows 'public' with read-only and 'private' with read-write access.
- ✗
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.
