ANS: DVI
A video production company uses removable media to transport multimedia files to partner and
customer sites. Often, the media has to be prepared with only very short notice. In the past, the time
taken to transfer files from the development workstations has resulted in delays and missed
appointments. To mitigate this issue, the company has procured USB 3.2 Gen 2x2 storage devices and
Windows PC workstation expansion cards. The devices and expansion cards support multiple USB
hardware port types. Which of the following adapter cables will enable the devices to take full
advantage of the highest transfer rate? ANS: Type C to Type C
,A support technician plugged a monitor with a USB C cable connector into a USB C port on the
computer, but the monitor would not function. Why would the monitor not work? ANS: It was not a
Thunderbolt version 3 cable
A support technician is installing a PCIe card that will use a combination of system memory and 8GBs of
dedicated memory. What type of card is the tech installing? ANS: Graphics
A support technician is working on a motherboard that is 12" x 9.6" and has seven expansion slots.
Which form factor is the technician working with? ANS: ATX
A support technician needs to install a legacy peripheral component interconnect (PCI) sound card.
Which of the following statements about PCI is NOT true? ANS: The PCI card can fit into the PCIe slot
A support technician opened the case to a PC and saw a square socket component. What component
has the support tech located? ANS: CPU
A support technician needs to install an optical disk drive in a new tower. Which panel should be
removed so that the technician can gain access to the optical drive and connect the cables? ANS:
Through the side panel
A support technician is connecting a current standard extended integrated drive electronics (EIDE) cable
to a PC's motherboard and knows that pin 1 on the cable must match up with pin 1 on the port. How can
the tech know where pin 1 is on the cable? ANS: Pin 1 has a red stripe
A support technician is installing a new SATA hard drive on a new computer. What is the best type of
cable connector the technician will plug in to supply power to the drive? ANS: 15-pin connector
A hardware technician is upgrading a device with multiple, identical central processing unit (CPU)
packages. What class of computer is the technician most likely upgrading? ANS: Server
, Which of the following central processing unit (CPU) architectures implements a system-on-chip (SoC)
where all the controllers, including video, sound, networking, and storage, are part of the CPU? ANS:
ARM
To mitigate the heat a high-end gaming system will generate, an engineer is using a liquid-based cooling
system in the design. Which of the following components are NOT a part of an open-loop, liquid-based
cooling system? ANS: Traditional heat sinks
A hardware technician is building a server that will process financial data in real-time and wants to use
error correcting code (ECC) RAM that will detect and correct errors, if possible. What other
considerations will the technician need to include to support the ECC RAM? (Select all that apply.) ANS:
ECC - Capable Motherboard
72-bit data bus
A hardware technician is working on a new desktop with memory that can send 128 bits of data per
transfer rather than 64 bits. What is this referred to as? ANS: Dual channel
A student is learning about computer hardware and the instructor selects them to identify the
component that executes program instruction code. How should the student respond? ANS: CPU
A hardware technician is scanning a computer's non-volatile storage devices for errors and infections.
Which of the following will the technician include in the scanning? (Select all that apply.) ANS: Hard disk
drives
Solid-state drives
Mass storage devices
As part of tech security, a technician loans a laptop to employees when they conduct business travel,
and upon return of the device, the technician reformats the drive and reloads the operating system and
all relevant software. After several years of following this process, the laptop becomes sluggish or
freezes up. What component is likely causing this type of computer behavior? ANS: SSD
