B is just normal usage, not a config issue.

D seems off, but I'm not sure if it breaks the rules.

I think C shows the rules are wrong too.

A is definitely a sign of misconfiguration.

I recall that if the rules are set up right, we shouldn't be able to send mail from inside to outside without going through the designated server. So, option C definitely seems wrong.

I practiced a similar question where the focus was on unauthorized access. I feel like option A could be a sign of issues too, but I'm not confident about that.

I'm not entirely sure, but I remember something about how SMTP should only allow traffic from specific IPs. Maybe option D could also indicate a problem?

I think option C might show a misconfiguration since it mentions delivering mail directly to an external contact, which shouldn't happen if the rules are set correctly.

I'm pretty sure Cisco was the first to provide commercial multiprotocol routers, so I'll go with option C.

Hmm, I'm a bit unsure about this one. I know a quota restricts imports, but I can't quite remember if that means the price goes up or down. I'll have to think this through carefully.

Okay, I've got this. The key is to create an authorization rule denying guest access. That will shut down the guest accounts and prevent any further unauthorized access.
