300-410 Question 264
Single answerA network administrator is troubleshooting an SNMPv3 configuration issue on a Cisco router. The SNMP Manager is unable to retrieve information from the router. Upon investigation, the administrator finds the following configuration on the router:
snmp-server group MGMT v3 auth snmp-server user ADMIN MGMT v3 auth sha mysecretpassword snmp-server host 192.168.1.100 version 3 auth ADMIN
What could be causing the SNMP communication failure?
- A
The SNMP group 'MGMT' is not configured for 'priv' (privacy) level.
- B
The SNMP user 'ADMIN' does not have the correct password configured.
- C
The SNMP server host IP address is incorrectly configured.
- D
The SNMPv3 user 'ADMIN' is not assigned to the SNMP group 'MGMT'.
Show answer and explanation
Correct answer: A
Explanation
The issue lies in the mismatch between the SNMP group configuration and the expected communication level by the SNMP Manager. The SNMP group 'MGMT' is set to 'auth' level, but if the SNMP Manager requires 'authPriv' (authentication and encryption), the communication will fail. To resolve the issue, the SNMP group should be updated to 'authPriv' level to use both authentication and privacy.
- A. Correct.
The SNMP group 'MGMT' is configured for 'auth' level, but the SNMPv3 user 'ADMIN' requires 'authPriv' (authentication and privacy) configuration if the host expects encrypted communication. This mismatch can cause communication failure.
- B. Incorrect.
The password for the SNMP user 'ADMIN' is correctly configured as 'mysecretpassword' using SHA. Therefore, this is not the issue.
- C. Incorrect.
The SNMP server host IP address (192.168.1.100) is correctly configured, so this is not the problem.
- D. Incorrect.
The SNMPv3 user 'ADMIN' is correctly assigned to the SNMP group 'MGMT' in the configuration, so this is not the issue.
