The video has many inaccuracies.
While the gist of it is correct, and physical OSI layers separation is indeed better for control (there is a valid reasons for "hardware" firewalls to exist), a lot of what she says is vastly extrapolated at best, or arguably wrong at worst.
And then, yes, regardless of the content, I'm pretty sure YouTube videos will be downvoted here.
Also, not even correct... Apparently, VPNs are magical solutions that cannot spy on your traffic, while using the hotspot of someone you know, and can ask questions to, is potentially exposing you to "malicious" operators; and also cloudflare is somehow "trustworthy"... ๐ฎโ๐จ
Edit: I checked the company behind that quiz website, and they are quite obviously marketing and UI oriented, so with that in mind, the quality of the quiz and of the offered "advice" is less surprising. I know that "privacy" and "security" are pretty trendy those days, but pretending to offer a training when you don't have the knowledge yourself is doing more harm than good... I wish they would humble themselves, take a step back, and reconsider.
