#1
What does RAID stand for in the context of data storage?
Redundant Array of Independent Disks
ExplanationRedundant storage technique combining multiple disks for data reliability.
#2
Which RAID level offers improved performance through data striping across multiple disks?
RAID 0
ExplanationStriping data across disks for enhanced performance, but no redundancy.
#3
What is the primary purpose of RAID 0?
Data striping
ExplanationRAID 0 primarily focuses on striping data for enhanced performance.
#4
What is the primary purpose of RAID 1?
Data Mirroring
ExplanationMaintains identical copies of data on separate disks for redundancy.
#5
Which RAID level provides both data striping and mirroring?
RAID 10
ExplanationCombines RAID 0 and RAID 1 for both performance and redundancy.
#6
What is the purpose of parity in RAID?
To provide fault tolerance
ExplanationParity information used to reconstruct data in case of disk failure.
#7
Which RAID level offers fault tolerance through distributed parity?
RAID 5
ExplanationRAID 5 provides fault tolerance by distributing parity across disks.
#8
In RAID 5, how many minimum disks are required for the array?
3
ExplanationAt least 3 disks required for RAID 5 array.
#9
What happens if a disk fails in a RAID 1 configuration?
Data remains accessible from mirrored disk
ExplanationData remains accessible from the mirrored disk.
#10
Which RAID level offers both fault tolerance and improved performance?
RAID 10
ExplanationRAID 10 combines fault tolerance and performance benefits.
#11
What is the minimum number of disks required for RAID 10?
4
ExplanationMinimum of 4 disks needed for RAID 10 implementation.
