I thought spikes were more about power surges, not EMI?

A is definitely EMI, electrical line noise is a classic example.

I practiced a similar question where they asked about types of interference, and I think electrical line noise was mentioned there too.

I feel like brownouts are more about power supply issues, not really EMI. I might lean towards electrical line noise for this one.

I think EMI is related to electrical line noise, but I'm not completely sure if that's the right term for it.

I'm a little confused by this question. I know we covered Distribution modes, but I can't quite recall the specifics. I'll try to eliminate the options that don't sound right, and then make an educated guess.

Creep sounds familiar as a possible damage type, but I feel like that might be more related to high temperature over time rather than condensate.

I remember something about the connection between bridge groups and routing modes, but I'm not entirely sure if it was in routed or transparent mode.

Definitely Hybrid. I remember learning about this technique in class, and it's a common way to crack passwords.
