You are building a Windows 2000 Advanced Server as the network file server for users. The system has 5 SCSI hard disks and converted to dynamic disk. The five hard disks are configured as follow:

-- Hard disk 0: 30 GB, System and Boot volume.
-- Hard disk 1: 20 GB, unused.
-- Hard disk 2: 30 GB, unused.
-- Hard disk 3: 40 GB, unused.
-- Hard disk 4: 50 GB, unused. You decide to create a RAID-5 volume that includes all unused hard disks using Windows 2000 Disk Management. What is the largest size of the RAID-5 volume?

A) 60 GB.

B) 80 GB.

C) 100 GB.

D) 120 GB.

E) 140 GB.

 

Correct answer is: A​

Explanation:

The equation to determine the amount of space used in the RAID 5 volume is the total number of space in the RAID 5 volume less one volume. The more disks that you have in the RAID-5 volume, the less the cost of the redundant data stripe.

In this question, there are 4 unused hard disks. The maximum size of each slot of the RAID-5 will be based on the smallest hard disk, which is 20 GB.

Available disk space = (4 * 20 GB) - 20 GB = 60 GB
