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

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

LSI
HP SmartArray
Promise

Check RAID level utilizing dedicated disk to store parity

RAID4
RAID5
RAID6

What is hotspare?

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

Check the correct statements relating to a hotspare

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

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

Is it possible to recover data if one of the member disks in a RAID10 failed?

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

Which parity function is usually used in a RAID5?

Lempel, Ziv, Welch
XOR
Huffman
Reed-Solomon

What controllers use delayed parity?

LSI
Promise
HP SmartArray

Check RAID levels which may utilize delayed parity

RAID10
RAID5
RAID6
RAID4
