Question:

Juana is responsible for servers in her company. She is finding a fault-tolerant solution that can handle two drives failing. Which of the following should she select?

A RAID 6.

RAID 6, disk striping with dual parity, uses a minimum of four disks with distributed parity bits. RAID 6 can handle up to two disks failing. RAID 3 is byte-level striping with dedicated parity and cannot tolerate more than a single drive failing. RAID 0 is disk striping, which cannot handle disk failure, and RAID 5, disk striping with distributed parity, can handle only one disk failing.
