Answer

To simplify disk management

Answer

To reduce the number of disks required

Answer

To increase data integrity

Question 7

Which of the following best describes the difference between disk mirroring and disk stripping?

Accepted Answer

Disk mirroring duplicates data, while disk stripping divides data across multiple disks

Answer

Disk stripping provides better data redundancy than disk mirroring

Answer

Disk mirroring uses more disks than disk stripping

Answer

Disk mirroring is faster than disk stripping

Question 8

What is the primary difference between disk mirroring and backups?

Accepted Answer

Disk mirroring provides real-time redundancy, while backups are usually scheduled and require manual restoration

Answer

Backups require more disks than disk mirroring

Answer

Disk mirroring is less expensive than backups

Answer

Disk mirroring is only for data protection against viruses

Question 9

Which scenario would most benefit from the implementation of disk mirroring?

Accepted Answer

A company requiring high availability for critical applications

Answer

A gaming system focused on performance over data safety

Answer

A personal user looking to save on storage costs

Answer

A backup solution for infrequently accessed files

Question 10

Which RAID level is commonly associated with disk mirroring?

Accepted Answer

RAID 1

Answer

RAID 5

Answer

RAID 10

Answer

RAID 0

Question 11

What is a potential drawback of disk mirroring?

Accepted Answer

Increased storage costs due to duplication of data

Answer

Faster data recovery speeds than non-mirrored setups

Answer

Higher risk of data corruption due to simultaneous writes

Answer

Decreased data accessibility during a disk failure

Question 12

What is the primary purpose of disk mirroring?

Accepted Answer

To provide redundancy by duplicating data across multiple disks

Answer

To compress data for better storage efficiency

Answer

To partition a single disk for better organization

Answer

To increase disk speed by reading from multiple disks simultaneously

Question 13

How does RAID 5 handle data recovery after a disk failure?

Accepted Answer

It uses parity to reconstruct the data from the failed disk

Answer

It stores duplicate copies of data on other disks

Answer

It relies on backups to restore data

Answer

It automatically repairs the disk

Question 14

In RAID 5, how is the parity information distributed among the disks?

Accepted Answer

It is striped across all the disks

Answer

Stored on a dedicated disk

Answer

Randomly assigned to different disks

Answer

Stored only in the first disk
