D. Inkjet
A. 802.11g
802.11g used the same 2.4 GHz frequencies as the 802.11b standard, but the
maximum theoretical throughput was increased from 11 megabits per second to
,54 megabits per second. correct answer Which of these wireless standards was
the first to introduce 54 Mbit/sec throughput on the 2.4 GHz band?
A. 802.11g
B. 802.11ac

A. A point-to-point connection to an office in another country
WAN (Wide Area Network) connections are between locations in different cities,
states, or countries. correct answer Which of these network types would MOST
likely be categorized as a WAN?
A. A point-to-point connection to an office in another country
B. A fiber connection to a building across a campus
C. A connection to a remote office on the other side of town
D. A link between a mobile device and an automobile
A. An app is using a large amount of CPU
Electronic devices generate a lot of heat, and the amount of heat from a CPU
increases dramatically as it is used. Although most mobile devices will dissipate
the heat using passive cooling, it's still possible to overheat the device in certain
circumstances. correct answer A technician is troubleshooting a mobile phone
that turns off after about an hour of normal use. Before powering off, the phone
displays the message, "High temperature detected." The phone is used inside the
building at room temperature, and is not used in direct sunlight. Which of the
following would be the MOST likely reason for this issue?
A. An app is using a large amount of CPU
B. The Wi-Fi network is overloaded
,C. The battery has low voltage
D. The mobile phone has liquid damage
A. Audit logs
Audit logs can be used to provide detailed information about print jobs, number
of pages printed, the usernames submitting the print jobs, and much more.
Tracking printer resource usage can use logs from the user's operating systems or
from the printer itself. correct answer A company has experienced a significant
increase in printing costs over the last few months. Which of the following would
provide the best way to track and manage these costs?
A. Audit logs
B. Print spooler uptime
C. Power usage monitor
D. Packet captures
A. Authenticate to iCloud on all devices
iCloud provides backups, synchronization, and app installation across multiple
Apple devices. Authenticating each device to the iCloud service provides
automatic synchronization over wireless or cellular networks. correct answer A
manager needs to have access to the same files, contacts, and email messages
across their MacBook, iPad, and iPhone devices. Which of the following would be
the BEST way to provide this synchronization?
A. Authenticate to iCloud on all devices
B. Connect all devices to the MacBook using a Lightning cable
C. Copy all user documents to Google Workspace
D. Configure automatic updates in the App Store
, A. Cable modem
A cable modem is commonly associated with a coaxial cable input using an F-
connector. The output from the cable modem commonly uses an RJ45 Ethernet
connector. correct answer A user in a remote office is connecting a device using
an F-connector. Which of the following would be MOST likely associated with this
connection?
A. Cable modem
B. Switch
C. Punchdown block
D. DSL modem
A. Capture card
A capture card can be used as an input for video and audio. This input can be
stored on a drive or used as input to a streaming service. correct answer An
administrator is building a computer system to stream live corporate events.
Which of the following should be installed to provide input for the live stream?
A. Capture card
B. Thermal pads
C. HSM
D. M.2
A. Check the local IP address configuration
The message of limited connectivity is usually based on a system with no access to
network resources. This is often occurs when a system is unable to contact a
DHCP (Dynamic Host Configuration Protocol) server and instead assigns itself an
APIPA (Automatic Private IP Addressing) address. A check of the local IP address
may identify a configuration error or a link-local address. correct answer A user is
reporting this message on their Windows computer taskbar icon: "Limited or No
