RAID Recovery Course - Content Analysis Test
Rows in a parity-based RAID are always even
false
true
What does parity analysis calculate?
percent of parity matches in disk set
percent of parity matches in each disk pair
percent of parity matches in each disk
If you see several mirror pairs in mirror map, it points to
RAID1
RAID10
RAID5
Ex-hotspare disk
If in parity analysis you see 0% parity for full disk set and 100% parity with one disk excluded, what the array level is?
RAID5 with a missing disk
RAID5 with a hotspare disk
full regular RAID5
certain type of RAID6
Disks from the same RAID have the same ratio of zeros and average entropy
false
true
What is the first step in RAID recovery?
entropy analysis
parity analysis
content analysis
Look at the picture and choose the possible variant
Disks {4,5,7} belong to one RAID; Disk 6 is a hotspare
Disks {5,6,7} belong to one RAID; Disk 4 is a hotspare
Disks {4,5,6} belong to one RAID; Disk 7 is a hotspare
Look at the picture on the right and guess RAID level
4-disk RAID 5 with one disk missing
RAID0
full 4-disk RAID 5
3-disk RAID 5 with a hotspare
Look at the picture on the right and check the possible RAID level(s)
RAID10
RAID 5 with a missing disk
full RAID5
RAID0
Look at the picture on the right and guess the possible RAID level
RAID 5 with a missing disk
RAID10
full RAID5
full RAID 5 with a hotspare
