You want to provide complete redundancy for all data stored on your hardware RAID 5 array. You install second h/w Raid 5. You want to create a mirror set of the original array. However when you right click the free space on new array you see no option to create a new volume or mirrrored volume. What should you do?

A

Convert both to dynamic disks

B

Create an empty extended partition on new disk

C

Create a single unformatted primary partition on new array

D

Format new disk array as a single NTFS primary partition

E

Format the new disk array as a single NTFS logical drive in an extended partition.

Your Windows 2000 Server computer contains a stripe set with parity on a four-disk array. You convert the stripe set with parity to a dynamic RAID-5 volume. Six months later, users report that disk access on the server is slower than it had been on the previous day, You use Disk Management and discover that the status of the third disk in the array is Missing. You want to recover the failed RAID-5 volume. What should you do first?

A

Replace the third disk and restart the server. Use disk Management to repair the volume

B

Ensure that the third disk is attached to the server and has power. Use Disk Management to reactivate the disk

C

Ensure that the third disk is attached to the server and has power. Use Disk Management to repair the volume

D

Install a new disk and create a single extended partition on the new disk. Restart the computer and allow Windows 2000 to automatically repair the volume on the extended partition

E

None of above
