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

false
true

What ensures redundancy in a RAID6?

calculating a special function over data blocks
there is no redundancy in a RAID6
calculating two special functions over data blocks
storing two copies of data

Check RAID level utilizing dedicated disk to store parity

RAID6
RAID4
RAID5

What controllers use delayed parity?

HP SmartArray
LSI
Promise

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

Choose the correct statement relating to RAID5EE

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

Check what delayed parity means

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

Check how data can be distributed in a RAID?

discretely – data is cut into blocks, blocks are written to all the disks in a certain pattern
contiguously over arrays member disks one by one
discretely – data is cut into blocks, blocks are written to all the disks randomly

Check RAID levels which may utilize delayed parity

RAID5
RAID6
RAID10
RAID4
