Q

When installing two PATA drives on a single cable, each drive must be configured with a jumper to designate it as either a primary drive (a.k.a. “master”) or a secondary drive (a.k.a. “slave”). The “cable select” jumper setting option automatically configures the drive as master or slave according to its position on a cable… T/F

A data storage solution that integrates HDD and flash memory into a single device is known as a: [2]

A
  • Hybrid drive

- SSHD

24

  • Mini-SD
  • xD
25
Q

Which of the following is a proprietary flash memory card format used mainly in older digital cameras?

A

xD

26
Q

Which one of the following is a data storage solution that combines multiple disk drive components into a single logical unit to increase volume size, performance, or reliability?

A

Redundant Array of Independent Disks (RAID)

27
Q

Which of the following RAID levels does not offer fault tolerance?

A

RAID 0

28
Q

Hardware RAID Level 0: [3]

A
  • Is also known as disk striping
  • Decreases reliability
  • Is suitable for systems where performance has higher priority than fault tolerance
29
Q

Hardware RAID Level 1: [3]

A
  • Requires at least 2 drives to implement
  • 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)
  • Is also referred to as disk mirroring
30
Q

Hardware RAID Level 5: [2]

A
  • 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)
31
Q

Examples of nested RAID levels include: [2]

A
  • RAID 1+0

- RAID 10

32
Q

Hardware RAID Level 10 requires a minimum of (drives):

A

4 Drives

33
Q

Which type of RAID creates a striped set from a series of mirrored drives?

A
  • RAID 1+0
34
Q

The term “Hot swapping” refers to the ability to replace computer system components without interrupting system operations. T/F

A

True

35
Q

Which of the following is an example of a hot-swappable drive? [3]

A
  • USB Drive
  • SATA Drive
  • eSATA Drive
36
Q

A Disk Defragmenter is a software tool used to rearrange data on magnetic drives in order to improve system performance. Defragmentation results in faster read/write operations of a magnetic hard drive’s read/write heads because defragmentation consolidates data into the smallest contiguous regions. This means that the heads can access data sequentially without seeking data fragments in different areas of a disk.
T/F

A

True

37
Q

An actuator arm assembly failure manifested by loud clicking noise emitted from the inside of the computer case is a problem symptom that should prompt for:

A

Data backup and hard drive replacement

38
Q

Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) enables monitoring a system for anticipated:

A

HDD Failures
