The simple answer is Yes. Now, you might be wondering why anyone would want to put themselves through the pain without setting up proper DNS and NTP?
Well, not all environments have the luxury of having either outbound connectivity and/or access to basic infrastructure services like DNS and NTP. This may come as a surprise to some, but there are customers out there that need to operate in very unique and constrained environments. One such example of this is typically from customers that need to deploy vSphere in a "dark site" where local infrastructure services like DNS and NTP are not available.
I recently re-validated this deployment model using the latest vSphere 7.0 Update 3 release running on an Intel NUC 11 which had no outbound connectivity and it was only connected to my laptop, which also had no outbound connectivity or access to DNS or NTP. Since this question recently came up from a customer who was looking to automate this, so I ran through the deployment workflow using the VCSA CLI Installer but this should also be possible with VCSA UI Installer as the same options are supported.
OK, so how do you make this work?
