A technician is looking to buy a new LCD monitor. Which type of LCD monitor has faster response times and is less expensive than others?
TN
IPS
LED
TN
The TN will have the fastest response time for this list. The IPS is quick enough for someone interested in gaming, but the LED and plasma monitors would show significant blur or lag when pushed to their limits by fast-moving gameplay
Which computer peripheral is most likely to use a mini-DIN 6 connector?
Keyboard
Monitor
Hard drive
Keyboard
A mini-DIN 6 connector is a round connector often called a PS/2 connector. It’s historically used for a keyboard or a mouse. If you have only more modern USB peripherals, you can buy a PS/2-to-USB adapter to plug them into one of these ports
Which type of storage device is composed of a conventional hard drive and a substantial amount of solid-state storage?
HDD
Mesh
Hybrid
Hybrid
A hybrid hard drive is a combination of a conventional magnetic hard disk drive and solid-state storage. The goal is to increase access speed for commonly accessed data while still providing larger capacity similar to a conventional HDD
An administrator ordered replacement printer paper that is thicker caliper than recommended by the printer manufacturer. What is the biggest risk in using this paper?
Paper will not feed
Paper will jam
Images will not print
Paper will jam
Thicker paper can cause paper jams, especially in printers with curved paper paths. Paper that is too thin may not get picked up by the printer rollers at all
You need to share printer on your network with multiple client operating systems, such as Windows, MacOS, and Linux. Which of the following services will best meet your needs?
AirPrint
TCP printing
Virtual printing
TCP printing
TCP printing allows clients with different OSs to send jobs directly to printers without worrying about intra-OS conflicts. Bonjour and AirPrint are both Apple services, and virtual printing allows you to print output to documents such as PDF files. Whenever sharing printers for remote printing, be sure to set proper user authentication on the print device
Which one of the following connector types are you most likely to find on the end of a CAT6a cable?
RJ-11
RJ-45
SATA
RJ-45
A CAT6a cable is a network cable, and you are most likely to find an RJ-45 connector at the end of it. RJ-11 connectors are for phone lines. BNC connectors are network connectors but are typically used with coaxial cable. SATA connectors are hard drive connectors
What type of printer technology will often use a roll of paper as opposed to individual sheets?
Ink-jet
Thermal
Laser
Thermal
Thermal printers will often use a roll of paper as opposed to individual sheets. Fax machines may use thermal technology, but a fax machine in itself is not a printer technology
Which RAM feature will detect errors within memory but is not able to fix them?
Parity
Non-parity
ECC
Parity
Parity checking is a rudimentary RAM error-checking scheme that offers no error correction
Which of the following types of printers requires the replacement of some sort of ink or toner? (Choose all that apply)
Laser
Thermal
Impact
Ink-jet
Laser
Impact
Ink-jet
Laser printers need toner cartridges, impact printers need ink ribbons, and ink-jet printers use ink cartridges. Thermal printers heat up paper to produce images
You are working on repairing a defective laser printer. Which of the following is a true statement regarding the imaging drum in a laser printer?
It can hold a charge only when it’s not exposed to light
It can hold a charge only when it’s exposed to light
It can hold a charge regardless of light exposure
It can hold a charge only when it’s not exposed to light
An imaging drum is a photosensitive drum that can hold a charge if it’s not exposed to light. It is dark inside an EP printer, except when the laser scanning assembly shines on particular areas of the photosensitive drum
What are the dimensions of a MicroATX motherboard?
- 6” x 9.6”
- 7” x 6.7”
- 9” x 2.8”
9.6” x 9.6”
A MicroATX motherboard is a 9.6″ square. ATX motherboards are 12″ × 9.6″, mini-ITX motherboards are 6.7″ × 6.7″, and pico-ITX motherboards are 3.9″ × 2.8″
When discussing video monitors, what is the term used to describe the number of pixels used to draw the screen?
Frame rate
Aspect ratio
Resolution
Resolution
Resolution is the number of pixels used to draw a computer screen. Refresh rate determines how many times per second the screen can be redrawn. Frame rate tells you how many frames per second the original content was filmed in. Aspect ratio defines the dimensions (width × height) of an image
You have three hard disks, each 1 TB in size. After installing them as a RAID-5 array in a computer, how much usable storage space will you have?
1.5 TB
2 TB
3 TB
2 TB
In a RAID-5 array, each stripe places data on n–1 disks, and parity computed from the data is placed on the remaining disk. The parity is interleaved across all the drives in the array so that neighbouring stripes have parity on different disks. Said differently, you lose the equivalent of one hard disk worth of storage to hold the parity information
Which of the following statements most accurately describes the functionality of the execute disable bit?
It prevents the CPU from working if the computer is stolen
It prevents the computer from being booted remotely in a PXE boot environment
It protects the computer from certain types of viruses or malicious code
It protects the computer from certain types of viruses or malicious code
The disable execute bit allows for the CPU to set aside an area of memory and refuse to execute any code placed into that memory location. Oftentimes this serves as a buffer area. The result is that malicious buffer overrun attacks are less likely to succeed
You need to enable clients to print to your network printers, regardless of the printers’ location worldwide. Which service will best suit your needs?
AirPrint
Virtual printing
Cloud printing
Cloud printing
Cloud printing allows for printing to a remote device, one that is not necessarily located on your local network. Essentially, you are using the Internet to send the print job from your device to the printer from which you want the output to come, and the printer can be located practically anywhere in the world
Which of the following connectors transmit analog signals? (Choose two)
VGA
RJ-45
RJ-11
HDMI
VGA
RJ-11
VGA is an analog video connector, and RJ-11 connectors are used with modems. Modems receive a digital signal from the computer but then modulate that signal to analog to transmit over common phone lines

Permanent
Ad hoc
On demand
Ad hoc
Wi-Fi and Bluetooth can be used to connect a printer temporarily to a single computer (or mobile device), and the connection does not have permanent status. This type of configuration is known as an ad hoc network connection
