John needs to provide fault tolerance on his computer running Windows 7 Home Premium. He wants to make sure it boots even if a disk fails. He has two disks on the computer and unallocated space on his second disk. Which of the following should he do?
Explanation
Answer - C - John should create a RAID-1 volume to provide fault tolerance on his computer running Windows 7 Home Premium.
Key Takeaway: Windows 7 enables you to expand and contract volumes without data loss and without requiring a reboot. You can create simple volumes, spanned volumes, striped volumes, mirrored volumes, and striped volumes with parity on dynamic disks. A mirrored or RAID-1 volume provides availability and fault tolerance, but does not improve performance. It uses two disks that are the same size. Any changes made to the first disk of a mirror set are also made to its mirror disk. If the first disk fails, the mirror is broken and the second disk is used until the first is repaired or replaced.
