LPI 201-450 Exam - Topic 14 Question 89 Discussion

What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)
A) One of the disks in /dev/md0 has failed and a spare disk is used to recreate full redundancy
B) The spare disk /dev/sda1 is used to restore full redundancy after the current recovery
C) The information [UU_] means, that the raid is missing one disk and is not fully redundant
D) The 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
E) The 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

Isn't it weird that GRUB Legacy needs that version 1.2 metadata?

Wait, are we sure about the spare disk being /dev/sda1?

I definitely recall that version 1.2 metadata is relevant for booting, so option D seems plausible, but I need to double-check that against what I studied.

I’m a bit confused about option E; I thought the numbers indicated the total disks and how many were in use, but I can't recall the specifics.

I remember practicing a question about RAID configurations, and I feel like option A might be correct since it mentions a disk failure and using a spare.

I think option C sounds familiar, but I'm not entirely sure if it means the RAID is missing a disk or just not fully redundant.

This is a good example of why it's important to really understand how RAID works. I'm going to carefully analyze each option and the information provided in the image to determine the correct answers.

I think options A and B are the most likely answers here. The image seems to show a RAID array with a spare disk being used to restore redundancy, which matches those choices.

[UU_] looks like it might indicate a missing disk, so option C could be correct. But I'm not sure about the other options - I'll need to double-check the details in the image.

Okay, the image shows some RAID-related information, so I'm guessing the answer has to do with RAID configuration or status. Let me think this through step-by-step.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and the image to figure out what information is actually contained in the /proc/mdstat excerpt.

Ugh, I'm not too familiar with Tropo, so this question is a bit of a challenge for me. I'll have to make an educated guess here. Maybe the scripts are saved in .xml format since that's a common markup language for web applications? Or possibly .js since Tropo apps are likely built with JavaScript? I'm not sure, but I'll give it my best shot.

Okay, I've got this. The question is asking how many variables are incorrectly identified, so I just need to compare the list to what I know about Altman's Model. I think I can figure this out.

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.
