• Question 211:

  Users report accessing a volume on the server is very slow. The server is located in a department break room. A network administrator checks the problem and determines one of the hard drives from the RAID 5 array has been stolen, and the array contains PII data. The Chief Executive Officer (CEO) wants to know which data is likely to be available to the thief. Which of the following should be the network administrator's response?

  A. Since a RAID 5 array uses parity, all the data on the drive could be recovered.
  B. Since the drive contains RAW data from a broken array, some data could be recovered with difficulty.
  C. Since the drive contains a duplicate of the other drives, all the data on the array will be available.
  D. Since a RAID 5 array stripes the data evenly over all the drives, no information could be recovered.
  D. Since a RAID 5 array stripes the data evenly over all the drives, no information could be recovered.

• Question 212:
