Implementing 802.1X for authentication sounds familiar, but I can't quite remember how it works in this context.

I'm not entirely sure about PAP; I think it might not be secure enough for our needs, but I recall it being mentioned in a practice question.

I remember we discussed VLANs in class, and creating a separate management VLAN seems like a solid option to isolate the devices.
