Resolution

1. Log in to ESXi host using vSphere Client
2. Navigate to Networking > Virtual Switches > vSwitch0.
3. Verify the number of physical NICs (uplinks) connected.
4. Remove one of the uplinks so that only a single physical NIC remains connected to vSwitch0.
5. Save the configuration.
   
   Example:
   If vmnic0 and vmnic1 are both connected, remove vmnic1.
   
   
6. Re-run the VCF Installer validation
