Partition Recovery Course - md-raid Test

The superblock part describing a particular disk is

the same only on adjacent disks
the same on all array member disks
different on each array member disk

The superblock part describing an array is

the same on all array member disks
different on each array member disk
the same only on first and the last disks

In what devices md-raid is commonly used?

DASes
Windows Servers
NASes

If you know that array member disks, say in RAID 5, are all of the same size, then

md superblocks are located at the same offset in the end of the disks
md superblocks are located at the same offset either in the beginning or in the end of the disks depending on superblock version
md superblocks are located at the same offset in the beginning of the disks
the disks will use the same partition layout

The main component of md metadata is

i-node
GPT or MBR table
superblock
header

Superblock includes two significantly different parts; one describes a RAID and other – a specific disk

true
false

Superblock is always located before data

true
false

How the number of a disk in the array is called in md-raid?

disk function
role
disk identifier

md-raid can consist of other mad-raid arrays

true
false

Where are copies of superblock stored?

on each array disk either in the beginning of the disk or in the end
only on the first member disk in the end
on each array disk always in the beginning
only on the first member disk in the beginning
