|
|
Platters of a magnetic hard drive spin at a rate measured in: |
Revolutions per minute |
|
|
The capability for replacing computer system components without causing interruption to the system operation is known as: |
Hot swapping |
|
|
Which of the following answers list(s) example(s) of hot-swappable drives? |

HDD SSD |
|
|
A type of media used as a secondary system storage in tablets and mobile phones is known as: |

|
|
A storage technology that combines multiple disk drive components into a single logical unit to increase logical volume size, improve performance, or reliability is known as: |
Redundant Array of Independent Disks (RAID) |
|
|
Which of the following solutions does not offer fault tolerance? |
RAID 0 |
|
|
What are the characteristics of RAID Level 0 |
It is known as disk striping Decreases reliability (failure of any disk in the array destroys the entire array) Is suitable for systems where performance has higher priority than fault tolerance |
|
|
What are the characteristics of RAID Level 1 |
Requires at least 2 drives to implement Is also referred to as disk mirroring Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data) |
|
|
What are the characteristics of RAID Level 5 |
Requires at least 3 drives to implement Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives) |
|
|
Which RAID type has the highest disk overhead? |
RAID Level 1 |
|
|
RAID Level 10 requires a minimum of how many drives? |
4 drives |
|
|
What refers to a nested (hybrid) RAID level? |
RAID 1+0 RAID 10 |
|
|
Which type of RAID level creates a striped set from a series of mirrored drives? |
RAID 10 |
|
|
