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

Check the correct RAID6 layouts

far symmetric/asymmetric
left symmetric/asymmetric
right symmetric/asymmetric
near symmetric/asymmetric

Check RAIDs utilizing mirroring for redundancy

RAID5
RAID6
RAID1E
RAID10

Check all the alternative names for RAID10

RAID0+1
RAID1+0
RAID1E
RAID01

Check the correct statements relating to a hotspare

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

Choose the correct statement relating to RAID5E

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

Choose the correct statement relating to RAID5EE

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

RAID criteria are usually placed in vertices of

RAID triangle
RAID square
RAID pentagon

Is it possible to recover data if more than one member disk in a RAID10 failed?

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

Check RAID levels which may utilize delayed parity

RAID10
RAID6
RAID4
RAID5
