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 RAID1E?

storing two copies of data
there is no redundancy in a RAID1E
calculating a special function over data blocks

Check RAID level utilizing dedicated disk to store parity

RAID5
RAID6
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

What ensures redundancy in a RAID6?

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

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

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