DRAG DROP (Drag and Drop is not supported)
A security administrator is given the security and availability profiles for servers that are being deployed.
Match each RAID type with the correct configuration and MINIMUM number of drives. Review the server profiles and match them with the appropriate RAID type based on integrity, availability, I/O, storage requirements. Instructions:
All drive definitions can be dragged as many times as necessary Not all placeholders may be filled in the RAID configuration boxes If parity is required, please select the appropriate number of parity checkboxes Server profiles may be dragged only once
If at any time you would like to bring back the initial state of the simulation, please select the Reset button.
When you have completed the simulation, please select the Done button to submit. Once the simulation is submitted, please select the Next button to continue.

See Explanation section for answer.

Answer(s): A

Explanation:

RAID-0 is known as striping. It is not a fault tolerant solution but does improve disk performance for read/write operations. Striping requires a minimum of two disks and does not use parity. RAID-0 can be used where performance is required over fault tolerance, such as a media streaming server.
RAID-1 is known as mirroring because the same data is written to two disks so that the two disks have identical dat a. This is a fault tolerant solution that halves the storage space. A minimum of two disks are used in mirroring and does not use parity. RAID-1 can be used where fault tolerance is required over performance, such as on an authentication server. RAID-5 is a fault tolerant solution that uses parity and striping. A minimum of three disks are required for RAID-5 with one disk's worth of space being used for parity information. However, the parity information is distributed across all the disks. RAID- 5 can recover from a sing disk failure.
RAID-6 is a fault tolerant solution that uses dual parity and striping. A minimum of four disks are required for RAID-6. Dual parity allows RAID-6 to recover from the simultaneous failure of up to two disks. Critical data should be stored on a RAID-6 system. http://www.adaptec.com/en-us/solutions/raid_levels.html
