How does RAID provide different levels of fault tolerance?

By using data mirroring and parity.

By using data compression and encryption.

By using data fragmentation and defragmentation.

By using data backup and restore.

By configuring multiple hard drives into an array

By using external storage devices

What is the purpose of different RAID levels?

To provide different methods of storing and protecting data

To increase the speed of the internet

To reduce the size of the hard drives

To improve the graphics quality

What is the primary purpose of using parity in RAID?

To provide fault tolerance without full data duplication

To increase data storage capacity

What does parity involve the use of in RAID systems?

An additional bit or block of data

What is the role of parity information in RAID?

To reconstruct data in the event of a disk failure

To increase the speed of data retrieval

How does parity work in RAID systems?

By calculating a value based on the data stored across multiple disks

By duplicating all data across multiple disks

By storing data in a single disk

What is the configuration of Single Parity (Used in RAID 5)?

Data and parity information are striped across multiple disks.

Data and two sets of parity information are striped across multiple disks.

Data is written to a single disk.

Parity information is not used.

What is the fault tolerance of Single Parity (Used in RAID 5)?

Can tolerate the failure of one disk.

Can tolerate the failure of two disks.

Can tolerate the failure of three disks.

Cannot tolerate any disk failure.

How does RAID 0 (Striping) work?

Data is split into blocks and each block is written to a separate disk drive.

Data is mirrored across multiple disks.

Data is written to a single disk drive.

Data is compressed before being written to disk.

When is RAID 0 typically used?

When performance is a priority and reliability is not.

When data redundancy is a priority.

When storage capacity is a priority.

When data compression is required.

How does RAID 1 (Mirroring) work?

Data is duplicated and stored on two or more disk drives.

Data is split and stored on multiple disks.

Data is compressed and stored on a single disk.

Data is encrypted and stored on multiple disks.

What is the primary goal of RAID 1?

To increase data processing speed.

For what type of storage is RAID 1 typically used?

Mission-critical storage that requires a minimal risk of data loss.

How does RAID 5 work?

Data and parity information are striped across three or more disks.

Data is mirrored across all disks.

Data is stored on a single disk.

Data is striped across two disks without parity.

What is one of the main advantages of RAID 5?

Good balance of performance, storage efficiency, and data redundancy

What is a disadvantage of RAID 5?

Parity calculation can slow down write operations

What happens if more than one disk fails in a RAID 5 array?

Data is mirrored to another disk

What makes RAID 5 a cost-effective solution?

It provides continuous data access as a priority

How does RAID 10 work?

Data is mirrored and then striped across multiple disks.

Data is striped and then mirrored across multiple disks.

Data is stored on a single disk.

Data is compressed and then stored.

What is one of the main advantages of RAID 10?

It provides high performance and redundancy.

It is the most cost-effective RAID level.

It has the fastest write speed.

What is a disadvantage of RAID 10?

It requires at least four disks and has higher cost due to duplication of data.

It has slow read and write times.

It does not support high volumes of data.

For what purposes is RAID 10 commonly used?

Storing high volumes of data, fast read and write times, and high fault tolerance.

Storing low volumes of data with slow read and write times.

Storing compressed data with low fault tolerance.

Why do small businesses use RAID?

For data protection and to maximize storage efficiency

To enhance graphics performance

What is one of the uses of RAID for home users?

For data backup and media storage
