RAID Recovery Course - RAID Levels Test

Synchronous RAID is the same as symmetric RAID

false
true

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

LSI
HP SmartArray
Promise

What minimum disk number is required for a RAID1E?

four
five
two
three

What is hotspare?

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

Check those RAID criteria RAID5 meets

large capacity and fault-tolerance
fault-tolerance and speed
speed and large capacity
speed improvement only

What ensures redundancy in a RAID5?

calculating a special function over data blocks
storing two copies of data
there is no redundancy in a RAID5

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

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

RAID0 is

redundant block array
redundant non-block array
non-redundant block array
non-redundant non-block array

Check how data can be distributed in a RAID?

discretely – data is cut into blocks, blocks are written to all the disks randomly
contiguously over arrays member disks one by one
discretely – data is cut into blocks, blocks are written to all the disks in a certain pattern
