Mosquito on a Cisco router? What is this, a crossover episode? I'm just going to pick D and hope for the best. At least it'll be more exciting than watching paint dry.

Haha, C is definitely a trap answer. Who uses usernames and passwords these days? I bet the real issue is with the ports. Let's go with B and see if that fixes it.

Nah, I don't think that's it. The question says the connection is being refused, so it's probably a port forwarding issue. Let's go with A and try to map the port directly in the IOS config.

Hmm, I think the answer is D. Seems like the default port for Mosquitto is 1883, so we should update the package.yaml file to reflect that.
