Question

A technician manages a server that contains sensitive data. The server currently has two hard drives, one hosting the operating system and other generic files and the second hosting sensitive data. The technician needs to implement a technology that would guard against data loss for only the sensitive data, while adding only one additional hard drive. Which of the following should the technician implement to avoid reformatting any drives?

Options

  • ARAID 0
  • BRAID 1
  • CRAID 3
  • DRAID 5

Why each option

To protect sensitive data from loss using only one additional hard drive without reformatting existing drives, the technician should implement RAID 1 on the drive containing sensitive data.

ARAID 0

RAID 0 (striping) provides no data redundancy and increases the risk of data loss, making it unsuitable for protecting sensitive data.

BRAID 1Correct

RAID 1 (mirroring) duplicates data from one drive to another, providing full redundancy. If the drive containing sensitive data fails, the mirrored drive ensures the data is still available, and many RAID controllers allow for dynamically adding a mirror drive without requiring a full reformat of the original data drive.

CRAID 3

RAID 3 (byte-level striping with a dedicated parity drive) requires at least three drives and typically involves reformatting all drives to create the array.

DRAID 5

RAID 5 (block-level striping with distributed parity) requires a minimum of three drives and typically involves reformatting all drives to create the array.
