2V0-41.24 Question 447
Select 2A network administrator is attempting to deploy NSX-T Data Center in their environment but encounters an issue where the NSX Manager appliance fails to successfully boot. Upon reviewing the deployment logs, the administrator notices that the appliance fails to connect to the configured NTP server and reports time synchronization issues. What steps should the administrator take to troubleshoot this issue?
- A
Verify that the NTP server is reachable from the NSX Manager appliance.
- B
Ensure that DNS resolution is correctly configured for the NSX Manager appliance.
- C
Check whether the NSX Manager appliance has the correct firewall rules to communicate with the NTP server.
- D
Re-deploy the NSX Manager appliance with default settings.
- E
Manually adjust the system time of the NSX Manager appliance to match the NTP server.
Show answer and explanation
Correct answers: A, C
Explanation
When troubleshooting NTP connectivity issues during the NSX Manager deployment, it is critical to verify network connectivity to the NTP server and ensure that appropriate firewall rules are in place to allow communication. These steps help isolate and address the root cause of the problem without resorting to unnecessary actions like re-deploying the appliance or manually adjusting the system time.
- A. Correct.
The NTP server must be reachable from the NSX Manager appliance to allow time synchronization. Network connectivity should be tested as part of troubleshooting.
- B. Incorrect.
While DNS resolution is important for general NSX Manager functionality, it is not directly related to NTP connectivity issues.
- C. Correct.
The NSX Manager appliance must have the appropriate firewall rules to allow communication with the NTP server on port 123 (UDP). Ensuring correct firewall configuration is crucial.
- D. Incorrect.
Re-deploying the NSX Manager appliance is a last resort and is not the first step when troubleshooting NTP connectivity issues.
- E. Incorrect.
Manually adjusting the system time is not a recommended troubleshooting step. Time synchronization should be automated via NTP to ensure consistency across the environment.
