300-425 Question 175
Select 3You are managing a Cisco CMX deployment configured with high availability (HA). The primary server is not responding, and the secondary server has not taken over as expected. Which of the following troubleshooting steps should you perform to resolve the issue?
- A
Verify that both the primary and secondary CMX servers have synchronized NTP settings.
- B
Ensure that the secondary CMX server is in the 'Standby-Hot' state.
- C
Check the cluster configuration to ensure that both servers are correctly assigned with their respective roles.
- D
Confirm that the CMX license on the secondary server matches the primary server’s license.
- E
Restart the primary server to force the failover process to the secondary server.
Show answer and explanation
Correct answers: A, B, C
Explanation
In a Cisco CMX high availability setup, proper synchronization of NTP settings, confirmation of the secondary server’s state as 'Standby-Hot,' and ensuring the cluster configuration is correctly established are essential for the HA functionality to work correctly. Troubleshooting these areas will help identify and resolve the issue. Licensing and restarting the server are not relevant to the initial troubleshooting steps for this scenario.
- A. Correct.
NTP synchronization is critical for proper operation and failover in a CMX high availability setup, as time discrepancies can cause HA to fail.
- B. Correct.
The secondary server must be in the 'Standby-Hot' state to be ready to take over when the primary server fails. If it is not in this state, the failover mechanism will not function.
- C. Correct.
The cluster configuration must be correctly set up, with the primary and secondary servers assigned their respective roles. Misconfiguration can prevent the failover process from working.
- D. Incorrect.
While licenses must be valid, the license type on the secondary server does not need to match the primary server for HA functionality to work. This option is irrelevant to the specific issue.
- E. Incorrect.
Restarting the primary server will not resolve the issue if the failover mechanism is not functioning properly. This step should only be done after verifying HA configuration.
