    Which RAID level provides block-level striping with dedicated parity?

    ক)
    RAID 0
    খ)
    RAID 1
    গ)
    RAID 5
    ঘ)
    RAID 10

    Explanation

    RAID 5 stripes data blocks across drives and stores distributed parity (not dedicated to one disk). It tolerates a single drive failure with rebuild. Writes incur read-modify-write overhead due to parity updates. It balances capacity, performance, and redundancy.
