I'm pretty confident that the arbiter is the correct answer since it doesn't hold data, just votes during elections.

I feel like the hidden node might have some role in elections too, but I can't recall the specifics.

I remember practicing a similar question, and I think the primary node is involved in more than just elections.

I think the key here is to focus on the specific wording of the question - it asks which node would "only" be used during an election. That suggests the answer is a node type that has a singular purpose in the election process.

Based on my understanding, the answer is C. Hidden nodes are not involved in the election process, so they would be the only node type not used during an election.

I'm pretty sure the answer is A. Arbiter nodes are only used during elections to help determine the new primary node.

Hmm, I'm a bit confused on this one. I know arbiter nodes play a role in elections, but I'm not sure if they are the only node type used exclusively during elections.

Hmm, I'm not totally sure about this one. It could be a social engineering threat, but it also seems like it could be an organizational threat if the caller is claiming to be from a large tech company. I'll have to think this through carefully.

I'm a bit confused by this question. Isn't a vulnerability scan just an automated tool, while a penetration test involves a human tester actively trying to exploit the system? I'm not sure if one is inherently more thorough.

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?

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?
