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

Which controller uses non-typical RAID6 layout – wide pace?

LSI
HP SmartArray
Promise

Check RAID level utilizing dedicated disk to store parity

RAID6
RAID5
RAID4

What is hotspare?

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

Check the correct statements relating to a hotspare

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

Choose the correct statement relating to RAID5E

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

Choose the correct statement relating to RAID5EE

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

Check what delayed parity means

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

What controllers use delayed parity?

Promise
LSI
HP SmartArray
