300-430 Question 179
Select 4An organization is using Cisco CMX with a high availability (HA) pair to ensure continuous location-based services. After a maintenance window, the secondary CMX server does not sync with the primary CMX server. Which of the following steps should be taken to troubleshoot this issue?
- A
Verify that both primary and secondary CMX servers have matching software versions.
- B
Check for proper configuration of the NTP server on both CMX servers.
- C
Ensure that the primary CMX server has the 'HA Primary' role properly configured.
- D
Test the network connectivity between the primary and secondary CMX servers.
- E
Verify that the secondary CMX server has a higher priority in the HA configuration.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
To troubleshoot CMX high availability synchronization issues, it is essential to ensure that both servers are running the same software version, have proper NTP configuration, and are correctly assigned their roles ('HA Primary' and 'HA Secondary'). Additionally, network connectivity between the servers must be verified. The priority setting, while important in determining failover behavior, does not directly address synchronization problems.
- A. Correct.
Matching software versions are required for proper synchronization between the primary and secondary CMX servers. A mismatch can cause the secondary server to fail to sync.
- B. Correct.
Accurate time synchronization is critical for the HA pair to function correctly. Misconfigured or unreachable NTP servers can lead to synchronization issues.
- C. Correct.
The primary CMX server must be properly configured with the 'HA Primary' role to establish the HA relationship and allow synchronization.
- D. Correct.
Network connectivity issues between the primary and secondary servers can prevent synchronization. Testing the connectivity ensures that the two servers can communicate.
- E. Incorrect.
The priority settings in the HA configuration determine which server is primary and which is secondary, but a higher priority on the secondary server will not resolve the sync issue in this scenario.
