Section 5.8 RAID

Which of the following drive configurations uses striping without fault tolerance?

a. RAID 0
b. RAID 5
c. RAID 1
d. Expanded volume set

RAID 0

You have an existing computer running Windows 7 Enterprise. You want to configure a RAID1 array in the computer. You install two new SATA drives, then use the RAID controller integrated into the motherboard to define a RAID1 array using them. When you boot the computer, Windows does not show the logical RAID drive you just created. What should you do?

a. In the BIOS, change the SATA disk mode to ACHI.
b. In the BIOS, change the SATA disk mode to RAID.
c. Install the drivers for the RAID controller.
d. Set the jumpers on the drives to use SATA I mode.

Install the drivers for the RAID controller.

You are configuring a new system and want to use RAID 0 array for the operating system using SATA disks and the RAID functionality built into the motherboard. Which of the following actions will you take as part of the configuration?

a. Set master/slave jumpers on the hard drives.
b. Set the disk mode to ACHI in the BIOS.
c. Set the disk mode to IDE in the BIOS.
d. Load the RAID drivers during operating system installation.

Load the RAID drivers during operating system installation.

You have been asked to implement a RAID 5 solution for an engineer’s desktop workstation. What is the minimum number of hard disks that can be used to configure RAID 5?

a. 2
b. 5
c. 6
d. 3
e. 4

3

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?

a. Data on both volumes is still accessible.
b. Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not.
c. Data on both volumes is not accessible.
d. Data on the RAID 0 volume is accessible; data on the RAID 1 volume is not.

Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not.

Which RAID configuration level provides increased performance using only two disks?

a. RAID 1
b. RAID 2
c. RAID 5
d. RAID 0

RAID 0 (Striping)

What is an advantage of RAID 5 over RAID 1?

a. RAID 5 provides redundancy; RAID 1 does not.
b. RAID 5 provides redundancy for the disk controller.
c. RAID 5 continues to operate with a failure in two disks; RAID 1 can only operate with a failure of one disk.
d. RAID 5 improves performance over RAID 1.

RAID 5 improves performance over RAID 1.

Your computer currently runs Windows 7 Enterprise edition. You want to create a RAID5 array using the newly-installed SATA disks. When you go to Disk Management, the option to create the RAID5 array is not available. what should you do?

a. Install an add-on RAID controller.
b. Upgrade the disks to dynamic disks.
c. Create a simple volume first, then add the remaining disks to the volume.
d. Upgrade to Windows 7 Ultimate edition.

Install an add-on RAID controller.
