1. When a new motherboard is being installed, between which two
components must thermal compound be applied? (Choose two.)
o CPU
o RAM
o chassis
o heat sink
o chipset
o motherboard
Explanation:
You must apply thermal compound between the new CPU and the heat sink/fan assembly to a
overheating the CPU. The thermal paste helps to conduct heat from the CPU to the heat sink.
2. A technician is explaining the differences between inkjet
printers and laser printers to a customer. Which two
comparisons should the technician make? (Choose two.)
o Inkjet printers are less expensive as an initial purchase than laser printers.
o A laser printer is significantly slower than an inkjet printer.
o Both laser and inkjet printers produce poor quality images.
o The laser printer output is dry after printing, but an inkjet printer may still
have wet ink on the paper after printing.
o Inkjet printers use plain paper to make economical prints, but laser printers
require more expensive thermal paper.
3. Which three components are typically found in laser printer
maintenance kits? (Choose three.)
o fuser assembly
o primary corona
o pickup rollers
o transfer rollers
o secondary corona
o paper trays
Explanation:
Laser printer maintenance kits typically contain components that wear and can be installed w
disassembly of the printer. Corona wires are internal components that would require a trained
to replace. Paper trays are components that are not typically replaced during maintenance, bu
replaced any time if damaged.
4. Place the six stages of the troubleshooting process in the correct
order.

5. Which three features can be configured in the BIOS settings to
secure a computer? (Choose three.)
o MAC filtering
o drive encryptio
o TPM
o file encryption
o TKIP key
o passwords
,tabbs
FINAL EXAM COMPOSITE ANSWERS CH 1 - 14
Explanation:
Passwords, drive encryption, and TPM are BIOS configurable security features. File encryption
and MAC filtering are security features not configured within BIOS.
6. What are two safety hazards when dealing with laser printers?
(Choose two.)
o high voltag
o hot components
o heavy metals
o proprietary power bricks
o unwieldy card cages
Explanation:
Laser printers require high voltage when initially powered on and to charge the drum in prepa
writing data to the drum. This high voltage requirement is why most laser printers are not nor
connected to a UPS. A laser printer also has a fuser assembly used to apply heat and pressure t
to permanently attach it to the paper. The laser printer must be unplugged and the fuser assem
allowed to cool before working inside the printer.
7. What three values must be added to the IPv4 properties of a NIC
in order for a computer to have basic connectivity with the
network? (Choose three.)
o subnet mask
o DHCP server address
o domain name
o default gateway
o speed and duplex
o IP address
Explanation:
The IP address, subnet mask, and default gateway address values should be added to the NIC p
order for the computer to have basic network connectivity. This can be done either statically o
dynamically with DHCP. An additional value that should be present if the computer is to be us
connect to the Internet is the DNS server value. A computer automatically attempts to locate a
server if configured to do so. A DHCP server address is not used. Finally, NAT is configured on
on a computer host, and speed and duplex settings are NIC hardware settings and not IPv4 pro
the NIC.
8. After a technician tests a theory of probable causes, what two
actions should the technician take if the testing did not identify
an exact cause? (Choose two.)
o Establish a new theory of probable causes.
o Randomly replace components one at a time until the problem is solved.
o Document each test tried that did not correct the problem.
o Verify full system functionality.
o Test all remaining possible causes starting with the most complex.
Explanation:
If the exact cause of the problem has not been determined after you have tested all your theor
a new theory of probable causes and test it.

9. What two motherboard components control the system boot
operations? (Choose two.)
o BIOS chip
o UEFI chip
o Northbridge chip
o Southbridge chip
o CPU
Explanation:
System boot services are provided by the motherboard BIOS and UEFI chips.
10. What are two types of wired high-speed Internet
connections? (Choose two.)
o cable
o satellite
o cellular
o DSL
o dial-up
Explanation:
Cable and DSL Internet technologies both use physical cabling to provide an Internet connecti
residence or a small business. Although dial-up is a wired technology, it does not provide a hig
Internet connection. Satellite and cellular connections provide a wireless Internet connection.
11. In what two situations would UDP be better than TCP as the
preferred transport protocol? (Choose two.)
o when applications need to guarantee that a packet arrives intact, in
sequence, and unduplicated
o when a faster delivery mechanism is needed
o when delivery overhead is not an issue
o when applications do not need to guarantee delivery of the data
o when destination port numbers are dynamic
Explanation:
UDP is a very simple transport layer protocol that does not guarantee delivery. Devices on bot
the conversation are not required to keep track of the conversation. UDP is used as the transp
for applications that need a speedy, best-effort delivery.
12. Which two laptop components are considered replaceable by
the customer. (Choose two.)
o battery
o integrated card reader
o mini-PCIe module
o RAM
o display
Explanation:
Customer-replaceable units (CRUs) do not typically require a lot of technical skill to replace. R
battery are two examples of a CRU. In contrast, a field-replaceable unit (FRU), such as a displa
motherboard, keyboard, or touchpad, commonly requires a technician to install.
