QUESTIONS AND ANSWERS!!
A new computer experiences a malfunction with a touch input device. A
support engineer disassembles the computer to diagnose the problem. While
troubleshooting, which component would the technician find as a 9-pin header
on the motherboard Answer - USB port -
Explanation:
Internal USB 2 connections are made via 9-pin headers, which accept up to two
4-pin port connections while the 9th pin is to orient the cable correctly.
A PC tech plugs a x8 PCIe adapter card into a x16 socket. What speed would the
card be capable of running? (Select all that apply.) Answer - x1
x8
Explanation:
Each PCIe adapter card supports a specific number of lanes. Ideally, the card
should be plugged into a port that supports the same number. Often a card will
only work at x1 if in a mismatched port.
,If insufficient slots are available, a card will fit in any port with an equal or
greater number of lanes. The card may work at x8.
A technician plugs a USB device into a computer and notices that the speeds
are slightly less than expected. The USB port and device are USB 3.x devices,
and the achieved speed is roughly 9 Gbps. What USB standard is in use?
Answer - USB 3.2 Gen 2x1
Explanation:
Variations of USB 3.x introduced new connector form factors and faster transfer
rates than previous versions. USB 3.2 Gen 2x1 is capable of speeds up to 10
Gbps.
A user tries to connect a second monitor to a computer. The computer has an
available digital visual interface (DVI) connector that outputs a digital signal
and the monitor has a video graphics array (VGA) connector. A technician
recommends a VGA to which type of cable? Answer - DVI-I
Explanation:
DVI-I is a technology that is capable of connecting a digital source to a digital
display or an analog source to an analog display. A VGA to DVI-I cable will
connect your digital computer to an analog monitor.
Which current USB standard supports 2 x 10 Gbps speeds and uses a USB-C
connector type? Answer - USB 3.2 Gen 2x2
Explanation:
The universal serial bus (USB) 3.2 specification deprecated some of the older
terms used to describe the supported transfer rates. USB 3.2 Gen 2x2
SuperSpeed USB is capable of 2 x 10 Gbps.
,A hardware technician replaces the central processing unit (CPU) on an
Advanced Micro Devices (AMD) motherboard. What must be applied when
connecting the heat sink to the CPU? Answer - Thermal grease
Explanation:
During the installation of the heat sink on top of the CPU, a small amount of
thermal grease must be applied in an X-pattern to allow for heat transference
to be most successful.
A laptop technician replaces the power supply in a desktop system. To do this,
the technician needs to know the output of the current power supply unit
(PSU). What is the PSU output capability measured as? Answer - WATTAGE
RATING
Explanation:
The PSU's output capability is measured as its wattage rating. Power is
measured in watts (W), calculated for electrical components as voltage
multiplied by current (V*I).
A technician builds a spare computer with an older motherboard and
purchases a new modular power supply. What type of motherboard connector
will the power supply most likely provide? Answer - 20+4-pin
Explanation:
Most modular power supply units (PSUs) have a 20+4-pin P1 adapter cable for
compatibility with older motherboards with a 20-pin port.
A technician installs memory into a computer that supports a multi-channel
configuration. A 4GB module is placed in bank A1 and a 16GB module is placed
, in bank B1. A diagnostic tool reports that 12GB is useable, but not as multi-
channel. What mode does the system use in making all of the memory
available? Answer - Flex
Explanation:
In flex mode, memory that is of equal value within each channel can work as
dual-channel while the remainder of the memory will work in single-channel
mod
A user complains that a computer is too slow when opening numerous
applications. A technician suggests purchasing a new computer that features
CMP capabilities to handle the user's workload. Which statement describes the
technician's suggestion? Answer - Two processors combined in the same
package
Explanation:
A multi-core central processing unit (CPU) is multiple processors combined in
one. This means that there are multiple execution units and registers. This is
referred to as chip level multiprocessing (CMP).
An engineer configures 6 disks in a workstation to be part of a redundant array
of independent disks (RAID) volume where one-sixth of the space on each disk
will be used for parity. Which RAID type does the engineer implement?
Answer - 5
Explanation:
RAID 5 requires a minimum of three drives but can be configured with more.
When configuring RAID 5, an equal portion of each disk is used for parity.
