Drag and Drop Question Given a file containing ordered number, i.e. "123456789," match each of the following redundant Array of independent Disks (RAID) levels to the corresponding visual representati
The correct answer is RAID 1; RAID 0; RAID 5; RAID 10. Each RAID level has a distinct visual signature: RAID 1 (mirroring) duplicates all data across two drives so both disks contain '123456789'; RAID 0 (striping) splits data across drives with no redundancy so each disk holds alternating segments like '1357' and '2468'; RAID 5 (stri

Explanation
Each RAID level has a distinct visual signature: RAID 1 (mirroring) duplicates all data across two drives so both disks contain '123456789'; RAID 0 (striping) splits data across drives with no redundancy so each disk holds alternating segments like '1357' and '2468'; RAID 5 (striping with distributed parity) spreads data AND rotating parity blocks across three or more drives so each drive has a mix of data segments and P() blocks; RAID 10 (mirror of stripes) combines RAID 0 striping with RAID 1 mirroring, producing pairs of mirrored drives that each hold striped data. Matching these visual patterns correctly requires understanding how each RAID level distributes and protects data across its member disks.
