Been taking certifications exams (Microsoft, then AWS) since early 2000s. Certification centers (eg Prometric) have cameras everywhere, and personnel watches you while you're taking the test, they make you put all your belongings into a locker, including watches. Workstations are locked down to the point that they can only run proprietary testing software.

I honestly prefer it to doing it remotely at home, where you have to show them your entire room (in the beginning and whenever they ask), install their software that wants full control to everything, and it still doesn't work half the time. One time I tried it told me bandwidth is insufficient - well, normally it's sufficient to have 2 or 3 Rokus stream in HD.
