RAID Recovery Course - RAID Introduction Test

Check the reasonably acceptable RAID block sizes

128 KB
2048 bytes
4094 bytes
512 bytes

How data is distributed to disks in a RAID5

data is divided into blocks of the same size and then blocks are written to the disks
in contiguous streams
data is divided into blocks of different size and then blocks are written to the disks

RAID criteria are usually placed in vertices of

RAID triangle
RAID square
RAID pentagon

NASes only use software RAID

true
false

On which disk or disks is RAID metadata stored?

on one particular member disk
on all member disks
on the first member disk

How data is distributed to disks in a RAID0

data is divided into blocks of the same size and then blocks are written to the disks
data is divided into blocks of different size and then blocks are written to the disks
in contiguous streams

What is start offset?

offset at which RAID user data starts
offset at which RAID metadata starts

Check those which can be RAID parameters

block size
start offset
block pattern
disk order

Is there a RAID meeting all the RAID criteria simultaneously?

yes
no

RAID is short for

Reliable Array of Inexpensive Disks
Reliable Array of Independent Disks
Redundant Array of Independent Disks
Redundant Array of Inexpensive Disks

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
