RAID Recovery Course - RAID Levels Test

In a RAID6, Q-parity function is always calculated over data blocks and P-parity block in a row

true
false

Is it possible to recover data if two member disks in a RAID6 failed?

yes, all data is recoverable
yes, but it depends on which disks failed
no

Check RAID level utilizing dedicated disk to store parity

RAID6
RAID4
RAID5

What is hotspare?

disk storing a copy of parity data
disk storing a copy of RAID data
blank disk already installed in a RAID in anticipation of a member disk failure

Check the correct statements relating to a hotspare

hotspare is always integrated into a RAID
hotspare can be either a standalone hard drive or be integrated into a RAID
hotspare drive may contain non-zero data
hotspare is always a standalone hard drive

Choose the correct statement relating to RAID5E

hotspare blocks are integrated in the end of RAID
hotspare blocks are evenly spread across array member disks
hotspare blocks are reserved on a standalone hard drive

How data is distributed to disks in a RAID1

data is written to the first disk until it is full, then to the next disk
two copies of data are stored on two disks

Check what delayed parity means

parity blocks are delayed within one of the member disks
parity blocks are larger than data blocks
data blocks are larger than parity blocks

Is it possible to recover data if one of the member disks in a RAID1E failed?

yes, but only part of the data is recoverable
depends on which disk failed
yes, all data is recoverable
no

What RAIDs utilize parity for redundancy?

RAID1+0
RAID1
RAID4
RAID5
