9. Which of the following RAID can be created by Windows 2000 Server and are described correctly?

A. RAID0- This technique has striping but no redundancy of data. It offers the best
performance but no fault-tolerance

B. RAID1 - This type is also known as disk mirroring and consists of two
drives that duplicate the storage of data

C. RAID2 - This type uses striping across disks with some disks storing error checking and correcting (ECC) information

D. RAID3 - This type uses striping and dedicates one drive to storing parity information

E. RAID5 - This type includes a rotating parity array and has excellent read performance.

Windows 2000 Server can create RAID0, RAID1, and RAID5 volume and the above descriptions are all correct. RAID2 and RAID3 are described correctly but cannot be created by Windows 2000 Server so are not the answer.

Answer, A,B,E

15. Your Windows 2000 Server has two Hardware RAID 5 array installed, as that Windows 2000 server is running several mission critical applications, you decided to setup a mirror volume using that two Hardware RAID 5 array. While you open the disk management and right click on the second hardware RAID 5, you cannot locate the option to create a new volume or mirrored volume. Why can't you create a mirror volume?

A. Because your hard disk is already a RAID 5 volume, hence cannot be used to create a mirror set again.
B. Because your hard disks are not configure as dynamic disks.
C. Because your hard disks are not configure as basic disks.
D. Mirrored volume is not supported in Windows 2000 Server.
E. The tools to create mirror volume are not installed.

You can create mirror volume in Windows 2000 Server only if your hard disk is configured as dynamic disks. Hardware RAID is transparent to Operating system, hence the operating system will use the RAID as a single disk and can further configure several of the hardware RAID to work as software RAID in Windows 2000 Server.

Answer: B

19. Your Windows 2000 Server is upgraded from a Windows NT 4.0 Server that has a Mirror sets that consists of two IDE Hard disks. Few months after the upgrade, one of the disks failed. How can you repair the failed hard disk?

A. Replace the failed hard disk with a disk configured as basic disk, and then repair the mirror volumes using Disk management using the new disk.
B. Replace the failed hard disk with a disk configure as dynamic disks, and then repair the mirror sets using Disk management.
C. Replace the failed hard disk with a disk configure as basic disk, and then copy all the files from the working hard disk to the replacement hard disk.

Since your Windows 2000 Server is upgraded from a NT 4.0 Server that has mirror sets, your hard disks are configured as basic disks. To repair the mirror sets without changing them to mirror volume (mirror volume is for Windows 2000 only and require dynamic disks) you need to add a basic disk and then use the disk management to repair the mirror sets. Note that if you replace the failed disk with a dynamic disk, you won't be able to see the repair option. Read below to understand how a mirror sets can be repaired:

From Microsoft Documentation:

=====================================================================================
To repair a basic mirrored volume (mirror set)

Open Disk Management
Right-click the mirrored volume you want to repair, click Repair Volume, and then follow the instructions on your screen.
The mirrored volume's status should change to Regenerating, then Healthy. If the volume does not return to the Healthy status, right-click the volume and then click Resynchronize Mirror.

Note
· You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
· To open Disk Management, click Start, point to Settings, click Control Panel, double-click Administrative Tools, and then double-click Computer Management. In the console tree under Storage, click Disk Management.
· If a basic disk containing part of a mirrored volume is disconnected or fails, the mirrored volume's status becomes Failed Redundancy and the disk's status remains Online. If this happens, you can try to repair the volume.
· When you repair a mirrored volume on a basic disk, Disk Management creates a new mirror on a healthy disk and then resynchronizes the new mirror.
· Repairing a mirrored volume on a basic disk requires an additional basic disk with sufficient free space for the new mirror. If an additional disk is not available, the Repair Volume option is unavailable and you cannot repair the volume.
· You must use a basic disk to repair a basic mirrored volume (mirror set). You cannot use a dynamic disk.

22. You create a RAID-5 volume in your Windows 2000 Server using 3 hard disks. Few months later, one of the disks failed and the disk access are slowing down. While you investigate the failed hard disk, you found that the status of the failed hard disk is missing. How can you recover the RAID-5 volume?

A. Make sure that the failed disk is attach to the controller properly and has the power turn on, then Right-click the Missing or Offline disk, and then click Reactivate Disk.
B. Replace the failed disk with a new hard disk, then reactivate the disk.
C. Make sure that the failed disk is attach to the controller properly and has the power turn on then use Disk management to repair the failed volume.
D. Replace the failed disk with a new hard disk, then repair the volume.

To answer this question, you have to know few important facts, one of them is the different between RAID-5 volume and the stripe sets with parity, basically if the volume is RAID-5 then it is using dynamic disks and is used only by Windows 2000 but not NT 4.0 Server. If it is stripe sets with parity, then it is upgraded from NT 4.0 Server. Repairing a RAID-5 and a stripe sets with parity is not the same, for RAID-5 you need to reactivate the disk, whereas stripe sets with parity use repair rather than reactivate. Also, for each status, there are a solution that associate with it, for this case, the status is missing, and the solution that you should use is Make sure that the failed disk is attach to the controller properly and has the power turn on, then Right-click the Missing or Offline disk, and then click Reactivate Disk. The reason is that, when the disk is missing, it could be due to the power supply for the disk is not on or the cable is no longer attached to the hard disk or the hard disk controller properly. Read below for further information.

From Microsoft documentation:

=================================================================================
Repairing a dynamic RAID-5 volume
In Disk Management, when a RAID-5 volume's status is Failed Redundancy, the volume is no longer fault tolerant To avoid data loss, you should attempt to repair the volume as soon as possible.

See Reconnect the disk and repair the RAID-5 volume if the RAID-5 volume's status is Failed Redundancy and one of the disk's status is Offline. The disk's name may be Missing. An icon (X) appears in the graphical view of the Missing or Offline disk.

See Reactivate the disk if the RAID-5 volume's status is Failed Redundancy and the disk's status is Online (Errors). An icon (!) appears in the graphical view of the partially failed disk.

To reconnect the disk and repair the RAID-5 volume

A disk containing part of a RAID-5 volume has been disconnected. Try to reconnect and reactivate the disk.

Make sure that the physical disk is turned on, plugged in, and attached to the computer. If necessary, turn on or reattach the physical disk.
Open Disk Management
Right-click the Missing or Offline disk, and then click Reactivate Disk.
See Replace a disk region in the RAID-5 volume if the disk containing part of the RAID-5 volume did not return to the Healthy status
