I'm just gonna go with B - the primary. It's the big boss, the one in charge, the one that everyone looks to for guidance. Surely that's the one that's only used during an election, right?

Hmm, I think it's C - the hidden node. It's like the secret agent of the cluster, lurking in the shadows until it's time to save the day!

I'm pretty sure it's D - the secondary node. That's the one that just stands by, waiting to take over if the primary kicks the bucket, right?

So, the secondary node is like the backup plan in case something goes wrong with the primary.

That's right. It's there to take over if the primary fails.

I'm not sure, but I think it could also be C) hidden node because it is not visible to clients.

Ooh, I know this one! It's gotta be A - the arbiter, right? That's the one that steps in when the primary and secondary can't agree on something.

I agree with Meghan, because an arbiter is used during elections to break ties.

Wait, isn't an arbiter like the referee in a soccer game? I'm so confused!
