Magnetic disks
SSDs
magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data.
An SSD, or solid-state drive, is a type of storage device used in computers. This non-volatile storage media stores persistent data on solid-state flash memory. SSDs replace traditional hard disk drives (HDDs) in computers and perform the same basic functions as a hard drive.
SCSI ID:
Identifies SCSI devices on a network
Identifies device embedded in the physical device on a SCSI chain
Serves as an interchangeable term for LUN
Identifies physical device on a SCSI chain
Identifies physical device on a SCSI chain
SCSI (Small Computer Systems Interface) is a smart bus, controlled with a microprocessor, that allows you to add up to 15 peripheral devices to the computer. These devices can include hard drives, scanners, printers, and other peripherals.
Which of the answers listed below refers to a method for identifying logical partitions on a SCSI drive?
Host ID
OUI
SCSI ID
LUN
LUN
A logical unit number (LUN) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard.
Which of the following requires termination?
SCSI chain
ATA
SATA
PATA
SCSI Chain
A SCSI chain is a term that describes the devices connected to one SCSI interface through one cable. Hardware terms, SCSI.
What is the maximum allowable number of devices that can be attached to a parallel SCSI bus?
4 devices
8 devices
16 devices
32 devices

Which of the following answers list(s) example(s) of hot-swappable drives? (Select all that apply)
USB drive
PATA drive
IDE drive
SATA drive
eSATA drive
USB Drive
SATA Drive
eSATA Drive
Serial Advanced Technology Attachment, also known as Serial ATA or SATA, enables mass storage devices, such as hard drives and optical drives, to communicate with the motherboard using a high-speed serial cable over two pairs of conductors.
eSATA is a SATA connector accessible from outside the computer, to provide a signal (but not power) connection for external storage devices. eSATAp combines the functionality of an eSATA and a USB port, and a source of power in a single connector. eSATAp can supply power at 5 V and 12 V.
Which of the answers listed below refers to a dedicated expansion card used for attaching external storage devices?
SATA card
IDE card
eSATA card
PATA card
EIDE card
eSATA card
What is the maximum number of devices that can be attached to a PC through a single PATA cable?
1
2
3
4
2
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.

Which of the following answers refer to SSD form factors? (Select 2 answers)
PCIe
M.2
mSATA
NVMe
SATA
M.2
mSATA
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.

Which of the following RAID levels does not offer fault tolerance?
RAID 5
Disk duplexing
RAID 0
Disk mirroring
RAID 1
RAID 0
Hardware RAID Level 0: (Select 3 answers)
Is also known as disk striping
Decreases reliability (failure of any disk in the array destroys the entire array)
Is also referred to as disk mirroring
Offers less volume capacity in comparison to RAID 1
Requires at least 3 drives to implement
Is suitable for systems where performance has higher priority than fault tolerance
Is also 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
Hardware RAID Level 1: (Select 3 answers)
Requires at least 2 drives to implement
Is also known as disk striping
Offers improved performance in comparison to RAID 0
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)
