CThe information [UU_] means, that the raid is missing one disk and is not fully redundant

Hmm, this question is a bit tricky. I'm going to go with C and E, as the [UU_] status seems to indicate a missing disk, and the [3/2] status looks like it's showing the number of disks and spares.

I think the answer is B and D. The spare disk /dev/sda1 is being used to restore full redundancy, and the version 1.2 metadata is for legacy bootloaders.

I'm pretty sure the answer is A and E. A failed disk and a spare disk being used to restore redundancy, and the [3/2] status showing the number of disks in the array and spares.

The correct answers are C and D. The [UU_] status indicates that the RAID is missing one disk and is not fully redundant, and the version 1.2 metadata is for legacy bootloaders like LILO and GRUB Legacy.
