Actual exam question for LPI's 201-450 exam

Question #: 9
Topic #: 15

What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)

AOne of the disks in /dev/md0 has failed and a spare disk is used to recreate full redundancy

BThe spare disk /dev/sda1 is used to restore full redundancy after the current recovery

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

DThe device is using version 1.2 metadata to allow LILO and GRUB Legacy to use /dev/md0 as the boot partition. This would not have been necessary with GRUB2

EThe information [3/2] means that 3 RAID disks belong to the array and 2 disks are spare. Together they equal the number of available disks

I thought GRUB2 handled boot partitions differently, interesting!

The [3/2] info is spot on, 3 disks in use and 2 spares!

Wait, is that really how the spare disk works?

Totally agree, that [UU_] means it's not fully redundant.

Looks like one disk in /dev/md0 has failed.

I’m leaning towards option E because I remember that the numbers indicate the count of disks in the array, but I’m not confident about the specifics of the spare disks.

I practiced a similar question where we had to identify RAID statuses, and I feel like option A could be correct since it mentions a spare disk being used.

I remember something about the [UU_] notation indicating redundancy issues, but I can't recall if it specifically means one disk has failed.

I think option C sounds familiar, but I'm not entirely sure if it means the RAID is missing a disk or just that it's in a degraded state.

I've got this! Sealed bids with public bid opening and contract award to the lowest bidder. Competitive undisclosed bids are the key here.

Hmm, let me think this through. I'll need to analyze the project network diagram and calculate the total float for Activity I.
