300-410 Practice Question: Snmp-server community MyCommunity RO…
snmp-server community MyCommunity RO 10\naccess-list 10 permit 192.168.1.0 0.0.0.255
What is the effect of this configuration?
⚠ Common exam trap
Cisco often tests the distinction between 'RO' and 'RW' in the community string command, and candidates may overlook that the access list is applied to the community, not globally, leading them to think access is unrestricted or that the community string is encrypted.
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
✓
SNMP read-only access is allowed only from the 192.168.1.0/24 subnet.
The configuration `snmp-server community MyCommunity RO 10` sets the community string to 'MyCommunity' with read-only (RO) privileges and applies access-list 10. The `access-list 10 permit 192.168.1.0 0.0.0.255` restricts SNMP access to only the 192.168.1.0/24 subnet. Therefore, only hosts in that subnet can query the SNMP agent with read-only access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SNMP read-only access is allowed only from the 192.168.1.0/24 subnet.
Why this is correct
The access-list 10 permits only 192.168.1.0/24, and the snmp-server community command applies that list to the MyCommunity string with RO. SNMP read-only queries using that community are therefore accepted solely from hosts within that subnet.
- ✗
SNMP read-write access is allowed from any host.
Why it's wrong here
The RO keyword grants read-only access, not read-write, and ACL 10 limits sources to 192.168.1.0/24 rather than any host. It is tempting because the RW keyword exists and, without an ACL, would permit read-write queries from any host.
- ✗
SNMP access is allowed from any host, but only read-only.
Why it's wrong here
Access list 10 permits only 192.168.1.0/24, and the community is tied to that ACL, so SNMP queries are restricted to that subnet rather than any host. It is tempting because omitting the ACL number would indeed allow read-only access from any source.
- ✗
The community string is encrypted in the configuration.
Why it's wrong here
The community string MyCommunity is stored in plaintext in the running configuration; Cisco IOS does not encrypt SNMPv1/v2c community strings. It is tempting because SNMPv3 supports authentication and privacy hashing, which would be the correct choice when encrypted credentials are required.
