Haha, you know someone's going to choose the 'one distribution port down' option just because it sounds the most complicated. But really, that's not going to cause a split-brain, just a potential performance impact.

Yeah, I'm with you guys on this one. C) VSL is down is the correct answer. I wonder how many people will get tripped up by the other options, though. They seem a bit too straightforward.

I agree with Lavonna. The VSL is the critical link that keeps the WLC pair in sync, so if that goes down, it can definitely lead to a split-brain situation. The other options don't seem as likely to cause that specific problem.

Hmm, this is an interesting question. I think the answer is C) VSL is down. When the Virtual Switch Link (VSL) between the two WLCs is down, it can cause a split-brain scenario where both WLCs think they are the active controller.

B: That makes sense. Without the VSL, the WLCs can't communicate with each other.
