How to tell if your vCenter is managed by VCF.
This is important to note for environmental administration. Since a VCF managed vCenter has to be managed by VCF in order for VCF to work effectively.
If it's a non VCF managed vCenter - there are fewer restrictions since the management of the vCenter is solely managed through vCenter.
vCenter 7.x
vCenter 8.x
The login screen can tell if youre vCenter is managed by VCF.
However sometimes the UI may not be accessible and you may have to verify this through a different method.
If the UI is unavailable, you can check by vCenter CLI
