Duplexing backup sets sounds like a dance move from the 80s. I can just see the RMAN Shuffle now.

Hmm, this is a tough one. I'm going to go with Options A and C, as they seem the most straightforward. The other options sound a bit too complicated to be true.

This question is tricky! I'm pretty sure Option F is correct, as duplexing would definitely require twice the number of channels. But the other options are a bit unclear to me.

I think Option C is correct, as we can duplex a tape backup to another tape. But I'm not sure about the others, they seem a bit confusing.

I think Option B is also true. You can duplex a non-duplexed backup set written to disk by backing up the backup set that is already on disk.

Option A seems logical, as duplexing would require additional channels. However, I'm not sure about the other options, especially the ones involving disk and tape duplexing.
