I vaguely recall that the host key is important for secure connections, but I can't remember if it authenticates users or just servers.

I feel like option A is wrong because the client doesn't send the host key; it receives it from the server.

I've got this one! The purpose of an SSH host key is to provide the server's identity information to connecting clients. That way, the client can verify they're connecting to the correct server. The answer is definitely B.

Okay, let me see here. The host key is used to identify the server, right? So I'm thinking the answer is either B or D. I'll go with B since that seems to directly state the purpose.

Hmm, I'm a bit unsure about this one. I know SSH host keys have something to do with verifying the server's identity, but I'm not totally clear on the exact purpose. I'll have to think about this one a bit more.

Hmm, this looks straightforward. I think I'll go with option B - employees[:-5] to exclude the last 5 elements, which should be the management team.

C) doesn't make much sense to me. I've never heard of the SSH host key being a 'root key' for signing user keys. Sounds like something out of a Dan Brown novel.

D) is an interesting one, but I don't think that's quite right. The host key is about verifying the server, not the user. Maybe the exam writers were trying to throw us off with that one.
