| Question 402 |
Which level of RAID refers to disk mirroring with block striping?
| RAID level 1 | |
| RAID level 2 | |
| RAID level 0 | |
| RAID level 3 |
Question 402 Explanation:
● The standard RAID levels comprise a basic set of RAID (redundant array of independent disks) configurations that employ the techniques of striping, mirroring, or parity to create
large reliable data stores from multiple general-purpose computer hard disk drives (HDDs).
●RAID 0: Stripping
● RAID 1: Mirroring
● RAID 2: Hamming code for error detection
● RAID 3: Byte-level striping with a dedicated parity disk
● RAID 4: Block-level striping with block-level striping with two parity blocks parity
● RAID 5: Block-level striping with distributed parity
● RAID 6: Block-level striping with double distributed parity.
