I thought RMSE was the best option for everything, but maybe not here?

Wait, can a confusion matrix even help here? Seems off.

RMSE is useful, but it won't tell you the direction of the error.

Totally agree, residual plots show the bias clearly.

Ah, I remember this from the lecture. Added and conversion functions are the ones that are counted for the FP count. I'll select that option and move on.

I'm a little confused by the wording of this question. Is it asking about the main divisions or just the primary division? I'll have to think it through step-by-step to make sure I don't miss anything.

Yes, and I think the other requirement is the IP address or FQDN of the Cisco UCM servers, since they are part of the networking configuration.
