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.
CORRECT ANSWER.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

8
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. CORRECT ANSWER.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.)
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. CORRECT ANSWER.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?
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. CORRECT ANSWER.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?
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. CORRECT ANSWER.Which current
USB standard supports 2 x 10 Gbps speeds and uses a USB-C connector
type?
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. CORRECT ANSWER.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?
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). CORRECT ANSWER.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?
20+4-pin
