RAID Recovery Course - RAID Levels Test
Check the correct statement relating to a symmetric RAID5
in a row, data blocks always start on the first disk
in a row, data blocks always start after parity block
What RAID type is shown on the right?
JBOD
RAID0
RAID5
RAID1
RAID10 and RAID01 are the same in RAID recovery
true
false
RAID criteria are usually placed in vertices of
RAID pentagon
RAID square
RAID triangle
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 drive may contain non-zero data
hotspare is always a standalone hard drive
Check technique(s) ensuring redundancy in RAIDs
parity
mirroring
disturbing data in blocks over member disks (striping)
Is it possible to recover data if half of the RAID10 member disks failed?
depends on which disks failed
yes, all data is recoverable
no
RAID5 is
non-redundant non-block array
non-redundant block array
redundant non-block array
redundant block array
What minimum disk number is required for a RAID1E?
four
five
three
two
Check the correct RAID6 layouts
far symmetric/asymmetric
left symmetric/asymmetric
right symmetric/asymmetric
near symmetric/asymmetric
