Which of the following RAID levels dos not offer fault tolerance

RAID 0

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

RAID 1+0

Which of the answers listed below refers to a nested RAID levels

RAID 1+0 , RAID 10

Which of the answers listed below describe the features of Solid-State drives(SSDs

Relatively high device cost, Lower capacity in comparison to magnetic drives, High performance

Hardware 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 data)

Hardware RAID level 5

Requires at least 3 drives to implement, Offers increases performance and fault tolerance( single drive failure does not destroy the array and lost data can be re-created by the remaining drives

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

Revolutions per minute

Which of the following requires termination

SCSCI chain

Examples of flash memory card formats include

SD, CompactFlash, MicroSD, miniSD, xD

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

Serial Interface, Point-to-Point connection, Does not require bus termination

Which of the following answers refer to a popular portable storage device utilizing flash memory

Thumb drive, USB drive, Flash drive

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. 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 device(Device 0) or secondary device(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 following answers lists examples of hot -swappable drives

USB drive, SATA drive, eSATA drive

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

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 enables connecting an M.2 device

B key slot, M key slot, B+M key slot

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

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

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

CDFS

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

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 statements refer to the characteristic features of magnetic drives

High capacity, Low device cost, Low performance

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

IOPS

SCSCI ID

Identifies physical device on a SCSI chain

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

Intermittent flashing

Hardware RAID level 0

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

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

LUN

Which of the following answers refer to SSD form factor

M.2, mSATA

Which of the following answers refers to internal data storage device types used in laptop computers

Magnetic disks, SSDs

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

NVMe

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

NVMe, SATA, PCIe

Due to size restrictions and compact nature of laptop devices, this type of storage media becomes less commonly found on new laptops

Optical Drives

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
