Understanding Data Storage and RAID

What does RAID stand for in data storage systems?

• Random Access Integrated Device

• Redundant Array of Independent Disks

• Rapid Access Information Database

• Reliable Automated Information Drive

Which RAID level is known for mirroring data across multiple disks?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

What is the primary purpose of using RAID in data storage systems?

• To increase the speed of data processing

• To provide data redundancy and improve performance

• To reduce the cost of storage

• To simplify data management

Which RAID level offers both striping and parity for data protection?

• RAID 0

• RAID 1

• RAID 5

• RAID 6

In a RAID 0 configuration, what happens if one disk fails?

• Data is automatically recovered

• All data is lost

• Only the data on the failed disk is lost

• Data is mirrored to another disk

Which of the following is a disadvantage of using RAID 5?

• High cost of implementation

• Slow read performance

• Slow write performance

• No data redundancy

What is the minimum number of disks required for a RAID 6 configuration?

• 2

• 3

• 4

• 5

Which RAID level is often used for applications requiring high read and write speeds?

• RAID 0

• RAID 1

• RAID 5

• RAID 10

In data recovery, what is the process of restoring data from a backup called?

• Data replication

• Data restoration

• Data migration

• Data synchronisation

Which of the following is NOT a benefit of using RAID?

• Increased data security

• Improved data access speed

• Reduced storage capacity

• Fault tolerance
