Ho do you know your Vagrant specs?

From this https://app.vagrantup.com/boxes/search I installed laravel/homestead.

It doesn't say what it is (linux type, php version, mysql version). Do i have to go manually into system via SSH and get this info for myself? And what info is necessary anyway? If it's Vagrant is newly installed Ubuntu 14.04 with PHP 7.2 is it considered to be same as newly installed Ubuntu 14.04 with PHP 7.2 on the server (if I don't do any changes)? Or do I have to export some config files?

Point of using Vagrant should be matching development/deployment. Yet I can't really find a lot of info about how to implement it in reality. Without using expensive tools.
