The --dns-forward-reverse-health command option in the SoS utility checks both forward and reverse DNS resolution, including PTR records. This command provides a comprehensive check of DNS health by verifying that both forward (A records) and reverse (PTR records) lookups are correctly configured for the components in the VMware Cloud Foundation environment. This is essential for ensuring proper connectivity and functionality across VCF components.

In VMware Cloud Foundation (VCF), licenses for vSphere and vSAN are managed through SDDC Manager. When adding a new cluster to an existing VI Workload Domain, the administrator should specify the required licenses in SDDC Manager, which centrally manages and applies the licenses to ensure compliance and compatibility across the environment.

In a VMware Cloud Foundation (VCF) environment with NSX federation across two sites, it is important to follow a specific upgrade sequence to maintain consistency and ensure the integrity of the NSX federation setup.

1. First, the NSX Local Managers at both sites need to be upgraded manually. This step ensures that local managers are updated before global managers, maintaining compatibility within the site-specific NSX environments.

2. Next, the active NSX Global Manager is upgraded using SDDC Manager. Upgrading the active Global Manager first ensures that the primary NSX control plane remains compatible with the updated Local Managers.

3. Finally, the standby NSX Global Managers are upgraded via SDDC Manager, completing the federation upgrade process while preserving global control plane redundancy.

This order avoids disruption in NSX federation functionality and aligns with VMware's best practices for NSX upgrades in federated environments.
