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

RAID 1+0

Which of the following requires termination?

SCSI chain

Examples of flash memory card formats include:

SD CompactFlash microSD miniSD xD

Which of the answers listed below refers to an older, portable device SSD form factor superseded by M.2?

mSATA

Which of the terms listed below refers to a proprietary flash memory card format used mainly in older digital cameras?

xD

Which of the following statements refer to the characteristic features of magnetic drives?

1. High capacity 2. Low device cost 3. Low performance

Hardware RAID Level 0:

1. Is suitable for systems where performance has higher priority than fault tolerance 2. Is also known as disk striping 3. Decreases reliability (failure of any disk in the array destroys the entire array)

Which of the following answers refer(s) to internal data storage device type(s) used in laptop computers?

1. Magnetic disks 2. SSDs

Which of the answers listed below refer to storage media device interfaces for SSDs?

1. PCIe 2. SATA 3. NVMe

Which of the answers listed below refer(s) to (a) nested RAID level(s)?

1. RAID 10 2. RAID 1+0

Which of the answers listed below describe the features of Solid-State Drives (SSDs)?

1. Relatively high device cost 2. Lower capacity in comparison to magnetic drives 3. High performance

Hardware RAID Level 1:

1. Requires at least 2 drives to implement 2. Is also referred to as disk mirroring 3. 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)

Hardware RAID Level 5:

1. Requires at least 3 drives to implement 2. 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 of the following answers refer to a popular portable storage device utilizing flash memory?

1. Thumb drive 2. USB drive 3. Flash drive

Which of the following answers list(s) example(s) of hot-swappable drives?

1. USB drive 2. SATA drive 3. eSATA drive

Which of the answers listed below refer to examples of optical disc drives?

CD-ROM drive DVD-ROM drive BD-ROM drive

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:

Data backup and hard drive replacement

Which of the symptoms listed below might be causing extended read/write times on a storage drive?

Depleted storage space Insufficient amount of RAM Disk fragmentation Loose cable connections Physical hardware faults

Which of the answers listed below refers to a method for identifying logical partitions on a SCSI drive?

LUN

A logical device interface used for accessing non-volatile memory storage devices attached via PCIe is known as:

NVMe

Restoring a RAID array after physical failure of one of the drives typically requires a very simple fix, which is the replacement of a bad drive. This solution will work for most of the RAID configurations except:

RAID 0

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

RAID 0

Platters of a magnetic hard drive spin at a rate measured in:

Revolutions per minute

An M.2 key is a notch on the pin contact surface of an M.2 expansion card which prevents its insertion to an incompatible socket. The 12 available M.2 key IDs are letters from A to M which indicate the location of notched pins on the card's contact surface and designate the type of interface a given card is compatible with. M.2 expansion cards used for solid-state storage applications have key IDs of B and M. The B-keyed M.2 SSD cards take advantage of 2 lanes of a PCIe link (lower read/write speed), the M-keyed M.2 SSDs use 4 PCIe lanes (higher read/write speed). M.2 SSDs with 2 notches on the card's pin contact surface (B + M) increase the card's compatibility as they can be installed in any of the two types of expansion slots on the motherboard.

True

When installing two PATA drives on a single cable, each drive must be configured with a jumper to designate it as a primary drive (Device 0) or secondary drive (Device 1). The "cable select" jumper setting option automatically configures the drive as Device 0 or Device 1 according to its position on the cable.

True

Which of the answers listed below refers to a dedicated expansion card used for attaching external storage devices?

eSATA card

Which of the answers listed below refer to the characteristic features of SAS?

1. Does not require bus termination 2. Point-to-point connection 3. Serial interface

Which of the following answers refer to SSD form factors?

1. M.2 2. mSATA

Which of the following answers refers to the maximum rpm value available in modern HDDs?

15000 rpm this

What is the maximum allowable number of devices that can be attached to a parallel SCSI bus?

16 devices

What is the maximum number of devices that can be attached to a PC through a single PATA cable?

2

Which of the answers listed below refers to an HDD form factor for laptop computers?

2.5 inch

Which of the following answers refers to magnetic drive form factor for desktops?

3.5 inch

Hardware RAID Level 10 requires a minimum of:

4 drives

Which of the following dedicated expansion slots/ports on the PC motherboard enable(s) connecting an M.2 device?

B+M key slot M key slot B key slot

Which of the following is a file system designed for optical media?

CDFS

Adding an eSATA device to a PC can be done either by attaching the device cable directly to the motherboard's integrated I/O panel, connecting it via eSATA port on a modular bracket mounted on the back of the PC case, or attaching it directly to a dedicated slot on the motherboard.

False

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

HDD/SSD failures

Which of the following metrics might be of help in diagnosing the declining performance of a storage drive?

IOPS

SCSI ID:

Identifies physical device on a SCSI chain

Which state of the HDD LED light typically indicates the drive's normal operation?
