Ok. this is driving me nuts

So we get a handout to study for an exam on Monday, right? It's all Ethernet fundamentals, and I can deal with it, but one question is driving me bonkers, I can't find it anywhere in the curriculum or in the book. To paraphrase, it wants to know what three standards Ethernet employs that will limit network service interruption. Now, maybe it's just a poorly worded question, but I have no idea what they're really asking for. Anyone help me out?
