Wait, I didn't know you needed a traversal zone for that!

Definitely B, that's the right setup for unknown domains.

I’m leaning towards option A, but I’m not confident. I remember something about SIP trunks, but it feels a bit vague now.

I keep mixing up the options, but I think option D sounds familiar. Didn't we discuss neighbor zones in relation to call routing?

I'm not entirely sure, but I feel like option C could be right since it mentions a DNS zone. We had a similar practice question about DNS configurations.

I think it might be option B, the traversal zone to a public DNS address. I remember something about that in the study materials.

This is a tough one, but I think I can figure it out. I'm going to read through the options slowly and try to visualize how each one would work for routing to an unknown domain.

Okay, I've got a good feeling about this. The question is specifically asking about routing to an unknown domain, so I'm guessing the answer has to do with some kind of DNS configuration. I'll carefully consider each option.

Hmm, I'm a bit confused on this one. I'm not sure what the difference is between a SIP trunk, traversal zone, and neighbor zone. I'll have to think it through carefully.

This one seems tricky, but I think I've got a strategy. I'll focus on the key phrase "route calls to an unknown domain" and try to eliminate the options that don't seem relevant.

Neighbor zone to the other business? Sounds like a great way to make some new friends.
