It's worth noting that these are Proctorio's (https://proctorio.com/) restrictions; they're just a third-party company that Amazon is using to administer the test. I've used a couple of similar systems (e.g. ProctorU - https://www.proctoru.com/, where a human will actually watch you via webcam(!), or ProctorTrack - http://www.proctortrack.com/), and "monitoring" of this sort is pretty much par for the course (no pun intended).
These companies are typically used in settings where some level of rigor is expected (e.g. administering an exam for an accredited university). In that context, I think these restrictions make sense in order to ensure some degree of validity in the test results (especially since you're only expected to run the software for the duration of the test).
