RAID Recovery Course - RAID Introduction Test

What is a minimum number of disks required to create a RAID?

3 disks
1 disk
2 disks

Which of the following is the JBOD parameter set?

start offset, block size
block size, disk order
start offset, disk order

Which of these sets of criteria are commonly applied to RAID arrays?

speed, size, and fault-tolerance
speed, size, and endurance
member disk count, speed, and fault-tolerance

RAID is short for

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

What type of the device can implement exotic RAIDs?

high-end hardware
low-end hardware
software

Can block size be 1 sector?

no
yes

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

Check the reasonably acceptable RAID block sizes

2048 bytes
4094 bytes
128 KB
512 bytes

How data is distributed to disks in a RAID0

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

In the list, mark block-based RAIDs

RAID5
RAID1
JBOD
RAID0

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