What is the advantage of RAID 5 over RAID 1? |
RAID 5 improves performance over RAID 1 - RAID 5 provides both fault tolerance and improve performance. |
|
|
Which RAID configuration level provides increased performance using only two disk? |
RAID 0 - (striping) uses two or more disks and provides an increase in performance but not fault tolerance. |
|

You install two new SATA drives, then use the RAID controller integrated in the motherboard to define a RAID 1 array using them. Windows does not show the logical RAID drive what should you do? |
Install the drivers for the RAID controller -Without the driver, windows will not be able to see the logical drive defined by the array. When you define the array, you configure the BIOS to use RAID as the SATA type. |

|
What is the minimum number of hard disks that can be used to configure RAID 5? |
3 - A RAID 5 array stripes data and parity information across multiple hard disks. |
|
|
Which of the following drive configurations uses striping without fault tolerance? |
RAID 0 - Uses disk striping and offers no fault tolerance. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. |

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID 1 volume uses space on Disk 2 and Disk 3. Disk 2 fails, which RAID is still accessible? |
Data on the RAID 1 ( mirrored) volume is accessible; data on the RAID 0 (striping) volume is not

You want to create a RAID 5 array using three newly-installed SATA disks. When you go to Disk Management, the option to create the RAID 5 array is not available, What should you do? |
Desktop operating systems support creating RAID 0 and RAID 1 array in Disk Management but do not support configuring RAID 5. To use RAID 5 on a client computer, you will need to use a RAID controller installed in an expansion slot or integrated in the motherboard. |
