Explanation

Explanation: A RAID-1 volume (also known as mirrored volumes) consists of two identical copies of a simple volume, each on a separate hard disk. Mirrored volumes provide fault tolerance in the event that one physical disk fails. This will not result in a slowdown in the event of disk failure. Incorrect answers: A: RAID-0 (also known as a striped volume) combines areas of free space from multiple hard disks into one logical volume. Unlike a spanned volume, however, data is written to all physical disks in the volume at the same rate. Because multiple spindles are in use, read and write performance is increased almost geometrically as additional physical disks are added to the stripe. But like extended simple volumes and spanned volumes, if a disk in a striped volume fails, the data in the entire volume is lost. B: Mirrored volumes (RAID-1) and RAID-5 volumes provide different levels of fault tolerance. Deciding which option to implement depends on the level of protection you require and the cost of hardware. The major differences between mirrored volumes and RAID-5 volumes are performance and cost. D: With this option there will be a definite slowdown in the event of disk failure.
