I've taken some tech certifications in the past and had the option of taking it at home (PSI) or at a test center (Pearson). The amount of intrusive demands the at home tests required and the absurd amount of monitoring made sure I never take a at home exam. Test centers I just bring my ID, leave my phone an keys in a locker and go to the assigned PC.

One memorable instance, I have a 37" 4K screen. In full screen mode the questions are in the top left and the multi choice answers are bottom right. The test proctor kept interrupting my exam because they assume I was looking away from the screen. I had to remind them repeatedly I'm using a large screen.
