Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Usually methods like RAID strategies are used in cloud computing to maintain integrity. What RAID stands for?

A	Redundant array of independent disks
B	Redundant arrangements of independent disks
C	Removal of array in independent disks
D	Remove array for integrity dependent

Explanation:

Detailed explanation-1: -What is the full form of RAID? Explanation: The full form of RAID is Redundant array of Independent Disks. This disk organization technique improves performance and reliability.

Detailed explanation-2: -The term RAID redundancy refers to the ability of certain types of RAID arrays to sustain multiple disk failures. RAID redundancy utilizes redundancy techniques such as data mirroring, data striping, and parity to minimize the risk of data loss due to disk failure.

Detailed explanation-3: -A method of mirroring or striping data on clusters of low-end disk drives; data is copied onto multiple drives for faster throughput, error correction, fault tolerance and improved mean time between failures.

Detailed explanation-4: -The most common types are RAID 0 (striping), RAID 1 (mirroring) and its variants, RAID 5 (distributed parity), and RAID 6 (dual parity). Multiple RAID levels can also be combined or nested, for instance RAID 10 (striping of mirrors) or RAID 01 (mirroring stripe sets).
