VCP-VCF Administrator 2024 Question 27
Select 3During the deployment of the VMware Cloud Foundation management domain using VMware Cloud Builder, the deployment fails at the NSX-T Manager configuration step. Upon reviewing the logs, you notice that the NSX-T Manager appliance was unable to establish a connection with the SDDC Manager. What steps should you take to troubleshoot and resolve the issue?
- A
Verify that the DNS records for the NSX-T Manager and SDDC Manager are properly configured and resolvable.
- B
Check the network configuration and ensure that all required ports between NSX-T Manager and SDDC Manager are open.
- C
Re-deploy the NSX-T Manager appliance from scratch without reviewing the existing configuration.
- D
Verify that the NSX-T Manager appliance has sufficient resources (CPU, memory, and storage) as per the VMware Cloud Foundation documentation.
- E
Ensure that the VMware Cloud Builder appliance is running the latest supported version.
Show answer and explanation
Correct answers: A, B, D
Explanation
The failure at the NSX-T Manager configuration step during the deployment of the management domain can be caused by DNS resolution issues, blocked ports, or insufficient resources on the NSX-T Manager appliance. By verifying DNS records, network connectivity, and resource requirements, these common issues can be identified and resolved, allowing the deployment to proceed successfully. Re-deployment without troubleshooting or focusing on unrelated components like Cloud Builder is not an effective solution.
- A. Correct.
DNS resolution is critical for VMware Cloud Foundation components to communicate properly. Misconfigured or missing DNS records can cause deployment failures.
- B. Correct.
Network connectivity, including the availability of required ports, is essential for the communication between NSX-T Manager and SDDC Manager. If ports are blocked, the connection will fail.
- C. Incorrect.
Re-deploying the NSX-T Manager appliance without understanding the root cause of the issue may result in the same error occurring again.
- D. Correct.
Resource requirements for NSX-T Manager must be met to ensure proper operation. Insufficient resources can lead to deployment failures.
- E. Incorrect.
While ensuring the Cloud Builder appliance is up to date is a good practice, it is not directly relevant to resolving this specific issue.
