RAID Recovery Course - RAID Introduction Test

Is there a special single standard for RAID metadata?

yes
no

Speed improvement is achieved due to the fact that:

data on a RAID is not fragmented
two data blocks on two disks can be read in one operation
each member disk in RAID is faster than a regular hard drive

Can block size be 1 sector?

no
yes

In the list, mark block-based RAIDs

RAID5
RAID1
RAID0
JBOD

Should start offset be equal to block size?

no
yes

On which disk or disks is RAID metadata stored?

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

Check the reasonably acceptable RAID block sizes

2048 bytes
512 bytes
128 KB
4094 bytes

Where is RAID metadata stored?

at the beginning of the member disk
at the end of the member disk
anywhere, depending on the implementation specifics

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

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

Is it obligatory to use identical disks to create a RAID?

yes
no
