I think B is a bit off, you don't need DBS for DMS archiving.

I believe backup data can indeed be stored in OSS, but I wonder if that applies to all types of backups or just specific ones.

I vaguely recall something about user roles needing to be 'administrator' or 'DBA' for certain operations, but I'm not completely confident about that.

I remember studying DMS features, but I'm not entirely sure if DBS is mandatory for archiving. It seems like it could be, but I need to double-check.

Okay, let me think this through step-by-step. The question is asking which statement about the DMS archiving feature is not correct. I'll need to analyze each option closely to determine the one that is incorrect.

Hmm, I'm not entirely sure about this one. I'll need to think it through and consider the implications of having an anonymous reporting channel for security policy violations.

I'm stumped on this one. Maybe I should just ask my cat for the answer. They're probably better at database management than I am.

Haha, D is obviously the wrong answer. Who do they think we are, database administrators? I'm just a lowly user trying to improve my query performance!
