You are installing a computer for a user. The user's specification calls for a RAID 1 volume.
What is the minimum system configuration that will support RAID 1?
1. A computer with two hard disks and Windows Server 2003.
2. A computer with three hard disks and Windows Server 2003.
3. >>A computer with two hard disks and Windows XP Professional.
4. A computer with three hard disks and Windows XP Professional.
Explanation : A Redundant Array of Inexpensive Disks (RAID) 1 configuration is a disk mirroring volume. It requires exactly two hard disks. One hard disk will act as a mirror to the other. It also requires Windows Server 2003 (or Windows 2000 Server, or Windows NT).
Windows XP Professional does not support any fault tolerance configurations, including RAID 1. Windows XP Professional does support RAID-0 (disk striping), however.
A RAID 1 configuration cannot use three hard disks. A RAID-5 (disk striping with parity) configuration requires at least three hard disks.
