NFC
NFC (Near-Field Communication) is a short-distance networking technology which communicates over
short distances of approximately 4 centimeters or less. An NFC-based authentication system would
recognize when a user comes into close proximity of a device and provide the proper authentication.
A hospital would like to use a hands-free authentication system based on the user's proximity to the
computer. Which of the following technologies would be the BEST choice for this system?
A. NFC
B. 5G
C. MDM
D. SSD
A. Plenum-rated
The plenum space is the area above a drop ceiling used for building air circulation. In the case of a fire,
this area should contain objects which have specific characteristics when heated. Network cables in
this area are categorized as plenum-rated, and their construction will limit smoke and toxic fumes.
Daniel is building out a new floor of office space for his company. Which of the following cables would
be the BEST choice to install in the active airspace above the drop ceiling?
A. Plenum-rated
B. Shielded twisted-pair
C. Coaxial
D. PVC jacketed twisted-pair
A. Replace the projector's video cable
The visual "glitches" displayed by the LCD projector are often associated with a failure of the digital
signal. The only connection between the laptop and the projector is the cable, so most of these issues
can be resolved by replacing the faulty cable.
A developer is connecting a laptop to an LCD projector, but the projected image is flickering and
occasionally part of the output will appear blocky and difficult to read. Which of the following should
resolve this issue?
A. Replace the projector's video cable
B. Turn the projector off and back on again
C. Update the laptop's video driver
D. Connect the laptop to a power source
D. Thunderbolt
The Thunderbolt standard was created by Intel to connect external peripherals to a computer at high
speeds. The Thunderbolt standard supports many different peripheral types, including displays,
external storage, Ethernet network connections, and many others.
A graphics designer needs to connect their macOS computer to a second monitor and an external
storage drive. Which of the following interface types would provide this connectivity?
,A. Lightning
B. DisplayPort
C. DVI-D
D. Thunderbolt
C. IaaS
IaaS (Infrastructure as a Service) is an option that provides CPU, memory, network connections, and
storage, and the customer installs and manages all of the software running on the infrastructure
hardware.
What cloud-based service provides hardware, but still requires the user to setup, configure, and manage
the operating system and applications?
A. SaaS
B. PaaS
C. IaaS
D. DaaS
B. RAID
A SAN (Storage Area Network) provides access to a relatively large storage system over the network.
RAID (Redundant Array of Independent Disks) is a common method of providing data redundancy for
storage systems.
Which of the following would be MOST associated with a SAN?
A. Bluetooth
B. RAID
C. APIPA
D. Cellular
C. Serial
Most infrastructure devices provide a management or console interface over a serial link. These have
traditionally used DB-9 (D-Subminiature size B - 9 pin) interfaces, but newer devices often use USB
(Universal Serial Bus) connections.
A network administrator is using a laptop computer to configure a switch over a direct cable connection.
Which of the following would BEST describe this connectivity?
A. Bluetooth
B. Thunderbolt
C. Serial
D. Lightning
D. Perform a hard drive diagnostic
If a slowdown is not associated with CPU, memory, or the network, then the issue may be with some
other type of hardware. A diagnostic of the hard drive would identify any issues that may be slowing
down the computer.
A manager in the accounting department is complaining of slow performance on her computer. Initial
troubleshooting shows low utilization of CPU and memory. A network speed test reports normal
throughput to the local network devices. Which of the following would be the BEST next step for
, troubleshooting this issue?
A. Boot to Safe Mode
B. Upgrade the BIOS
C. Replace the memory modules
D. Perform a hard drive diagnostic
C. Check the power cable
When troubleshooting, the easiest possible solution should usually be the first one to check. This
particular system has already been in use, and the system administrator was the person who moved it
from one location to another. Of the available options, checking the power cable should be the first
thing to check when power issues arise.
A server administrator has moved a database server from a lab to a data center. After installing the
server in a data center rack, the system does not power on. None of the system lights are on, and the
power supply and cooling fans do not spin up. Which of the following should be the FIRST
troubleshooting step for this issue?
A. Replace the power supply
B. Reseat all of the internal components
C. Check the power cable
D. Replace the motherboard
C. Bluetooth
Bluetooth networks are PANs (Personal Area Networks) that provide a short-distance connection to
local peripherals. For example, it's common to use a Bluetooth link to connect to headsets, wireless
mice, keyboards, or speakers.
A user is traveling and has enabled airplane mode on their laptop, but they would still like to use their
wireless headset. Which of these settings should be enabled to allow this functionality?
A. Wi-Fi
B. USB
C. Bluetooth
D. Cellular
B. Secured prints
With secured prints, the user can define a PIN (Personal Identification Number) on their computer,
and this PIN must be used on the printer to start the printing process. This process ensures the output
is not sitting unattended on the printer.
A user has submitted a job to a network printer, but the printer will not begin to print until the user has
typed their PIN on the printer console. Which of the following would BEST describe this scenario?
A. Badging
B. Secured prints
C. Active Directory
D. ADF
