Your friend has a Lenovo Idea Pad N580 laptop, and the hard drive has failed. Her
uncle has offered to give her a working hard drive he no longer needs, the Toshiba
MK8009GAH 80-GB 4200-RPM drive. Will this drive fit this laptop? Why or why not?
~Yes, the drive form factor and interface connectors match.
~No, the drive form factor matches but the interface does not match.
~Yes, the drive form factor, spindle speed, and interface all match.
~No, the drive form factor and interface do not match. - answer No, the drive form factor
and interface do not match.
You have four 2.5" hard drives on hand and need a replacement drive for a desktop
system. The documentation for the motherboard installed in the system says the board
has six SATA 3 Gb/s connectors and one IDE connector. Which of the four hard drives
will work in the system and yield the best performance?
~Ultralock IDE ATA 4500-RPM 3.5" HDD
~WD 3.5" 7200-RPM SATA 3.0 HDD
~Seagate IDE ATA 4500-RPM 3.5" HDD
~WD 2.5" 4500-RPM SATA 6 Gb/s HDD - answerWD 3.5" 7200-RPM SATA 3.0 HDD
RPM is revolutions per minute. It has the highest amount and will give the best
performance.
You are setting up a RAID system in a server designed for optimum fault tolerance,
accuracy, and minimal downtime. Which HDD is best for this system, assuming the
motherboard supports it?
~Hot-swap 2.5" SATA 2.0 SSD
~Hot-swap 3.5" SATA 3.0 10,000-RPM drive
~3.5" SATA 3.0 15,000-RPM drive
~2.5" SATA 6 Gb/s SSD - answerHot-swap 3.5" SATA 3.0 10,000-RPM drive
*SATA 3.0 is fast and has a minimal downtime than SSD. Also the hot-swapping
technique will have more fault tolerance
You have two matching HDDs in a system, which you plan to configure as a RAID array
to improve performance. Which RAID configuration should you use?
RAID 0
RAID 1
RAID 5
RAID 10 - answerRAID 0
It is the simplest technique which used 2 or more drives to increase the disk space of
the system, which increases performance.
, Which RAID level stripes data across multiple drives to improve performance and
provides fault tolerance? - answerRAID 5
It stripes the data and uses parity checking to provide fault tolerance
Which of the following situations allows for data not to be lost in a RAID array?
RAID 0 and one hard drive fails
RAID 1 and one hard drive fails
RAID 5 and two hard drives fail
RAID 10 and three hard drives fail - answerRAID 1 and one hard drive fails
It is a kind of mirroring which copies the date on one drive to another drive. So if 1 drive
fails the data is not lost
A laptop has an SD card slot that no longer reads cards inserted in the slot. Which is the
first and best solution to try? The second?
~Download and install the latest drivers from the laptop manufacturer for the card slot.
~Purchase a USB memory card adapter to replace the SD card slot.
~Replace the card reader on the system board, being careful to only use parts sold or
recommended by the laptop manufacturer.
~Update Windows on the laptop.
~Reinstall Windows on the laptop. - answerFirst, Download and install the latest drivers
from the laptop manufacturer for the card slot
Then, Update Windows on the laptop.
Explain how a DVD manufacturer can advertise that a DVD can hold 4.7 GB, but
Explorer reports the DVD capacity as 4,706,074,624 bytes or 4.38 GB.
~Manufacturers are allowed to overadvertise their products.
~The manufacturer measures capacity in decimal and the OS measures capacity in
binary.
~The actual capacity is 4.7 GB, but the OS requires overhead to manage the DVD and
the overhead is not included in the reported DVD capacity.
~The DVD was formatted to have a capacity of 4.38 GB, but it could have been
formatted to have a capacity of 4.7 GB. - answerThe manufacturer measures capacity
in decimal (base 10) and the OS measures capacity in binary.
You discover Event Viewer has been reporting hard drive errors for about one month.
What is the first solution you should try to fix the problem?
~Use the chkdsk command to repair the drive.
~Use Explorer to reformat the drive.
~Replace the drive with a known good one.
~Download and install firmware updates to the drive from the hard drive manufacturer. -
answerUse the chkdsk command to repair the drive.
