9.    You are newly hired as a network administrator for a workgroup. The

workgroup server has two 6GB disks. The first has 3GB used and the

second has 2GB used.

Required Results: Without reformatting the hard disks, implement a fault-tolerant partition.

Optional Results: Provide for the highest level of fault tolerance without buying another hard disk. Use the maximum amount of space that will work with your RAID solution.

Proposed Solution: Purchase two RAID 1 duplexing controllers. Implement duplexing. Use all the available free space on both hard disks to create a 3GB duplexed partition.

A.    The proposed solution meets the required results.

B.    The proposed solution meets the required results and one of the optional results.
