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.

I'm not sure about option F though. Does a duplexed backup set always use twice as many SBT channels?

I agree with you, Roselle. Option B makes sense for RMAN duplexed backup sets.

I think option B is true because you can duplicate a backup set already on disk.

I'm not sure about option F. I think option C is true because a non-duplexed backup set written to SBT can be duplexed to tape by backing up the backup set that is already on tape.

I agree with you, Noelia. Option F is also true because a duplexed backup set always uses twice as many SBT channels as a non-duplexed backup set for the same number of files.
