I’m a bit confused about the device profiles; I don’t recall them being a common issue, so I’m leaning away from option C.

This question feels similar to one we practiced where the certificate setup caused issues. I think both A and D could be the right answers.

I'm not entirely sure, but I think self-signed certificates with the same CN could create problems, which makes option D seem plausible.

I remember something about FQDN issues causing registration failures, so option A might be a strong candidate.
