VCP-VCF Administrator 2024 Question 313
Select 3During the VMware Cloud Foundation bring-up process, the deployment fails at the step of deploying the Management Domain. The logs indicate a failure connecting to the NSX Manager, with an error stating 'Cannot establish a connection to NSX Manager API endpoint.' What steps should you take to troubleshoot and resolve this issue?
- A
Verify that the NSX Manager VM is powered on and accessible via its management IP address.
- B
Check the NTP configuration on the VMware Cloud Builder appliance and ensure it is synchronized with the NSX Manager.
- C
Reboot the ESXi hosts in the Management Domain to refresh the environment.
- D
Ensure that the DNS resolution is correctly configured for the NSX Manager FQDN.
- E
Manually reinstall the NSX Manager appliance using the OVF template.
Show answer and explanation
Correct answers: A, B, D
Explanation
The bring-up process relies on proper connectivity between VMware Cloud Builder and NSX Manager. Common issues include network connectivity, DNS resolution, or time synchronization problems. Verifying that the NSX Manager is powered on, checking NTP synchronization, and ensuring proper DNS resolution are critical steps to diagnose and resolve the connectivity failure.
- A. Correct.
The NSX Manager must be powered on and reachable via its management IP address. If the VM is not powered on or there are network connectivity issues, communication will fail.
- B. Correct.
NTP synchronization is critical for VMware solutions to function properly. A time drift between the NSX Manager and the Cloud Builder appliance can cause API communication failures.
- C. Incorrect.
Rebooting the ESXi hosts is not a standard troubleshooting step for this issue and is unlikely to resolve the NSX Manager connectivity problem.
- D. Correct.
DNS resolution issues can prevent the NSX Manager FQDN from being reachable, leading to API endpoint connectivity issues.
- E. Incorrect.
Manually reinstalling the NSX Manager appliance is not recommended at this stage. This is a drastic measure and should only be considered after exhausting all other troubleshooting steps.
