RAID Recovery Course - RAID Levels Test

What minimum disk number is required for a RAID5?

three
five
four
two

Is it possible to recover data if one of the member disks in a RAID6 failed?

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

Check RAID level utilizing dedicated disk to store parity

RAID5
RAID4
RAID6

Which parity functions are usually used in a RAID6?

XOR and Reed-Solomon
Reed-Solomon and Huffman
Lempel, Ziv, Welch (LZW), and Huffman
XOR and Huffman

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

HP SmartArray
LSI
Promise

RAID6 is

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

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

Check what delayed parity means

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

Which parity function is usually used in a RAID5?

Reed-Solomon
XOR
Lempel, Ziv, Welch
Huffman

RAID10 and RAID01 are the same in RAID recovery

false
true
