Professor Messer 220-1101 Practice Exam 1 Flashcards
The printer in the accounting department has stopped all printing
processes. The print queue shows seven jobs in the queue waiting
to be printed. Which of the following would be the BEST next
troubleshooting step?
❍ A. Send a test job to the printer and move it to the top of the queue
❍ B. Restart the printer’s spooler
❍ C. Install an updated version of the printer driver
❍ D. Delete everything in the queue and resend the print jobs
The Answer: B. Restart the printer’s spooler
The print spooler is the software responsible for storing print jobs and
sending them to the printer. If the printer spooler has failed or has
stopped, then none of the print jobs will be sent to the printer.
The incorrect answers:
A. Send a test job to the printer and move it to the top of the queue
Since the print spooler is the issue, it won’t matter where a print job might
be in the queue. A test print job will sit at the top of the queue just like
any other print job.
C. Install an updated version of the printer driver
The printer driver on a client workstation is responsible for formatting the
print job in a way the printer can properly interpret during the printing
process. Changing the print driver won’t fix problems with the print
spooler.
D. Delete everything in the queue and resend the print jobs
If the spooler is having problems, then deleting the print jobs will only
require users to resend the print requests, which will then sit in the queue
and not print.
. A user’s print jobs to a new multifunction printer produce pages of
garbled text, but jobs from other users are printing normally. Which of the
following would be the MOST likely reason for this issue?
❍ A. Printer driver specifies secured prints
❍ B. Faulty network cable
❍ C. Print driver is configured for PCL
❍ D. Application is not authorized to print
The Answer: C. Print driver is configured for PCL
The page description language configured in a printer driver must match
the language on the printer. If a device prints to a PostScript printer using
Hewlett-Packard’s PCL (Printer Command Language), the output will
appear garbled and unreadable.
The incorrect answers:
A. Printer driver specifies secured prints
Secured printing allows the user to associated their print job with a PIN
(Personal Identification Number), and the job will not print until the PIN
is entered at the printer console. This process does not cause the output to
appear garbled or corrupted.
B. Faulty network cable
A faulty cable would cause the printer to receive data slowly or not at all.
The output of the printer would not be affected by a faulty Ethernet cable.
D. Application is not authorized to print
A print authorization is commonly determined by the user’s rights and
permissions and is not based on the application. If a user did not have
rights to print, then no print job would be queued and no output
would be created.
A network administrator has received a ticket complaining of port
flapping on an Ethernet switch. Which of the following would be the
MOST likely reason for this issue?
❍ A. Firewall rule is blocking traffic
❍ B. Faulty crimp on an Ethernet connector
❍ C. Excessive jitter measurements
❍ D. Duplex mismatch
The Answer: B. Faulty crimp on an Ethernet connector
Port flapping describes a network interface that constantly transitions
between connected and disconnected. This can sometimes be related
to software or firmware, but is most likely associated with a hardware
issue. For example, a faulty cable or connector could cause intermittent
connectivity and create a flapping Ethernet port.
The incorrect answers:
A. Firewall rule is blocking traffic
Denying or allowing traffic on a firewall would not cause an Ethernet
interface to physically disconnect or connect itself from the network.
C. Excessive jitter measurements
Jitter measures the time between network frames, and excessive jitter could
disrupt real-time voice or video communication. However, excessive jitter
would not cause an Ethernet interface to physically disconnect or connect.
D. Duplex mismatch
A duplex mismatch would certainly cause performance issues and
slowdowns, but it would not cause an Ethernet link to constantly
disconnect and reconnect.
A user has powered on their computer and received the message
“Operating system not found.” A check of the system shows that the
SATA drive cables are properly connected. Which of the following would
be the NEXT best troubleshooting step?
❍ A. Boot to Safe Mode
❍ B. Replace the boot drive
❍ C. Restore from a known good backup
❍ D. Check for removable drives
The Answer: D. Check for removable drives
If a USB (Universal Serial Bus) storage device is connected to a computer
and the BIOS (Basic Input/Output System) is checking USB devices
before the primary storage drive, the “Operating system not found” error
could appear with some USB devices. To avoid this error, the boot order in
the BIOS can be changed, or the USB device can be disconnected during
the boot process and reconnected after the operating system has started.
The incorrect answers:
A. Boot to Safe Mode
Safe Mode is a Windows mode used to launch the operating system with
minimal services and OS requirements. Safe Mode requires a bootable
drive, so the error message in this question would prevent Safe Mode
from starting.
B. Replace the boot drive
There’s not enough information to determine if the boot drive is bad or
faulty, so immediately replacing it would be premature. If there aren’t any
removable storage devices connected to the system, then running hardware
diagnostics of the drive would be a good next step before considering a
hardware replacement.
C. Restore from a known good backup
This question doesn’t provide enough information about the state of the
primary boot drive, so making any significant changes to the data on the
drive would not be the best next step.
Which of the following would be MOST likely found on an optical disc?
❍ A. Document archive
❍ B. Operating system boot files
❍ C. RAID parity files
❍ D. BIOS configurations
The Answer: A. Document archive
An optical disc such as a DVD-ROM (Digital Versatile Disc - Read Only
Memory) has the advantage of a relatively large storage area and the ability
to write once and never worry about an accidental deletion. The storage of
documents and other files is a common use of optical discs.
The incorrect answers:
B. Operating system boot files
Although it is possible to boot an operating system from an optical disc,
it’s not a common use of the format. It’s much more common to store
operating system files on a local storage drive with a higher storage
capacity and throughput, such as a hard drive or SSD (Solid-State Drive).
C. RAID parity files
A RAID (Redundant Array of Independent Disks) array requires that all
of the data and parity information reside on the local storage drives. Parity
information would not be stored on an optical disc.
D. BIOS configurations
BIOS configurations need to be accessible from the motherboard of a
computer, and not from other storage devices. BIOS configurations would
not be found on an optical disc
A technician is connecting a laptop to an LCD projector in a conference
room. The display on the laptop works properly, but the projector image
is constantly flickering and pixelating. The technician has modified the
resolution and refresh rates, but the projector image continues to flicker.
Which of the following would be the BEST next troubleshooting step?
❍ A. Replace the video cable
❍ B. Disable the laptop display
❍ C. Replace the projector bulb
❍ D. Power cycle the projector
The Answer: A. Replace the video cable
A display issue associated with flickering and poor video quality would
commonly point to the connection between the video adapter and the
display device. In the case of an LCD (Liquid Crystal Display) projector,
there’s sometimes a very long (and very worn) cable that can cause signal
issues to show on the projected image.
The incorrect answers:
B. Disable the laptop display
Disabling the laptop display won’t help with any signal problems. This
would probably also hinder the troubleshooting process because you
wouldn’t be able to properly see the display information due to all of the
flickering and pixelating.
C. Replace the projector bulb
The bulb in an LCD projector either works or doesn’t, so it will be very
obvious if the bulb is faulty. In this example, the projector bulb is working,
but the information displayed on the projector is difficult to see.
D. Power cycle the projector
The projector itself would not commonly cause any display flickering
or image problems, so power cycling the projector wouldn’t normally
resolve this type of problem. If all other troubleshooting tasks fail, then
power cycling everything might be an option, but it wouldn’t be the first
troubleshooting step
A newly installed MFD provides an option to “scan to SMB.” Which of
the following would BEST describe this feature?
❍ A. Print jobs can be sent from mobile devices
❍ B. All scans are checked for malware
❍ C. Files are stored on a Microsoft share
❍ D. Documents are scanned from the cloud
The Answer: C. Files are stored on a Microsoft share
SMB (Server Message Block) is the protocol used by Microsoft operating
systems to share files, print jobs, and other information between other
Microsoft OS devices. Many MFDs (Multifunction Devices) can scan a
document and store the scanned file on a central network share
using SMB.
The incorrect answers:
A. Print jobs can be sent from mobile devices
Many mobile devices can send jobs to a local printer, but this feature isn’t
part of the scanning process.
B. All scans are checked for malware
Although it’s important to protect against all sources of malware, it would
be unusual for a newly scanned document on a local MFD to contain any
malicious software.
D. Documents are scanned from the cloud
Many MFDs can support input from different sources, but the scan to
SMB feature describes the location of the output file once the original
document has been scanned
While configuring a new workstation in the lab, one of the engineers
recommends using 255.255.255.0. What part of the configuration is this
associated with?
❍ A. Default gateway
❍ B. Subnet mask
❍ C. DNS server
❍ D. IP address
The Answer: B. Subnet mask
Subnet masks are used by a device to determine what subnet it’s connected
to. Subnet masks are a series of binary ones that are used to “mask” the
subnet address from the host address. Instead of representing this mask
in binary, it’s almost always shown in decimal form. Common decimal
representations of subnet mask start with 255, such as 255.255.255.0.
The incorrect answers:
A. Default gateway
A default gateway on an internal lab network will most likely be using
private IP (Internet Protocol) addressing starting with 10, 172, or a 192.
IP addresses cannot start with an octet of 255. Therefore, a default gateway
in this environment would not have an IP address of 255.255.255.0.
C. DNS server
Since an IP address cannot start with the octet of 255, this address would
not be associated with a DNS server.
D. IP address
The IP address of a device cannot start with 255. It’s most likely that a
device in a lab would use an internal IP address that starts with an octet of
10, 172, or 192
A user’s smartphone shows a black screen and does not respond to any
screen taps or button presses. A check of the SIM card shows a red label
but no physical damage. Which of the following is the MOST likely
reason for these issues?
❍ A. Overheating
❍ B. Digitizer failure
❍ C. Liquid damage
❍ D. Invalid SIM card
The Answer: C. Liquid damage
Most smartphones and tablets include a liquid contact indicator
(LCI). This indicator is usually white, and it can often be seen without
disassembling the device. If the LCI turns pink or red, the device has been
in close contact with liquid.
The incorrect answers:
A. Overheating
An overheated device will remain off until the system has cooled. A
message will be displayed on the screen describing the overheating
condition.
B. Digitizer failure
A digitizer failure may cause the screen to become unresponsive, but the
device should still respond to button presses.
D. Invalid SIM card
An invalid SIM card would cause the device to lose connectivity with
the mobile provider, but the smartphone would still work normally and
respond to user input
A user would like to access email from their Windows 10 laptop using a
smartphone’s Internet connection. Which of these technologies needs to
be enabled on the laptop?
❍ A. LTE
❍ B. 802.11
❍ C. NFC
❍ D. IR
The Answer: B. 802.11
802.11 wireless connections can be used to access a smartphone configured
as an Internet hotspot. The laptop will communicate to the smartphone
over 802.11, and the smartphone is used to connect to resources on
the Internet.
The incorrect answers:
A. LTE
LTE (Long-Term Evolution) may be used by the smartphone for Internet
data communication, but the laptop does not communicate using LTE.
C. NFC
NFC (Near Field Communication) is a short-distance wireless technology
commonly used for payment systems or in-person information exchange.
NFC is not used for connecting to a hotspot on a smartphone.
D. IR
IR (Infrared) is often used to control other IR devices, such as
entertainment centers or televisions. IR is not used during the
hotspot connection process
Which wireless standard can operate in the 5 GHz band and provides
approximately 10 Gbit/sec of throughput?
❍ A. 802.11ac
❍ B. 802.11g
❍ C. 802.11ax
❍ D. 802.11n
The Answer: C. 802.11ax
The 802.11ax standard, or Wi-Fi 6, can operate in either the 2.4 GHz or
the 5 GHz band, and the maximum theoretical throughput is nearly 10
gigabits per second.
The incorrect answers:
A. 802.11ac
802.11ac, or Wi-Fi 5, operates in the 5 GHz band and can provide almost
7 gigabits per second of total throughput.
B. 802.11g
802.11g operates exclusively in the 2.4 GHz band, and can provide a
maximum throughput of 54 megabits per second.
D. 802.11n
Although 802.11n, or Wi-Fi 4, can operate in the 2.4 GHz band and
the 5 GHz band, the maximum theoretical throughput of 802.11n is 600
megabits per second.
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
The Answer: 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.
The incorrect answers:
B. Switch
A switch is usually associated with Ethernet connections, and Ethernet
commonly uses RJ45 connectors and not F-connectors.
C. Punchdown block
A punchdown block is often used instead of connectors, and individual
wires will be physically pressed or “punched” into the block. A punchdown
block is not commonly associated with F-connectors.
D. DSL modem
A DSL (Digital Subscriber Line) modem uses POTS (Plain Old
Telephone Service) with RJ11 connectors to provide connectivity to the
Internet service provider. A DSL modem does not commonly include
F-connector interfaces.
Which of these connection types use coax to provide Internet data, voice,
and video over the same wire?
❍ A. DSL
❍ B. Cable broadband
❍ C. ONT
❍ D. PoE
The Answer: B. Cable broadband
Cable television brought video into everyone’s home, and now voice and
Internet services are included on the same coax cable.
The incorrect answers:
A. DSL
DSL (Digital Subscriber Line) uses a pair of copper wires to provide
Internet access over the same connection as a traditional telephone service.
C. ONT
An ONT (Optical Network Terminal) is a demarcation point commonly
used for fiber to the premises. Although the ONT may include a coax
connection for television, it does not commonly combine voice, video, and
Internet over coax.
D. PoE
PoE (Power over Ethernet) is a convenient way to provide a power source
for a device without connecting to a power outlet. PoE does not provide
any consolidation of services over coax cable, however
A network administrator is deploying a firewall to the cloud using an API
to configure the device. Which of the following would BEST describe
this deployment type?
❍ A. SDN
❍ B. IaaS
❍ C. LDAP
❍ D. DKIM
❍ E. VPN
The Answer: A. SDN
SDN (Software Defined Networking) allows the functions of a
networking device to be split into logical units and virtualized into a
software-based deployment. This allows for easy deployment of switches,
routers, firewalls, and other networking devices into a cloud-based
infrastructure.
The incorrect answers:
B. IaaS
IaaS (Infrastructure as a Service) is a cloud model that provides the
fundamental resources needed to deploy an operating system and
application into the cloud. A common IaaS deployment might include
storage, CPU, networking, and a base operating system installation. IaaS
does not provide API deployment functionality for cloud-based firewalls.
C. LDAP
LDAP (Lightweight Directory Access Protocol) provides a standard
method of communicating to a directory service. LDAP does not provide
a method of deploying software-based infrastructure devices into the cloud
D. DKIM
DKIM (Domain Keys Identified Mail) is a technique for digitally
signing a domain’s outgoing email message. The recipient of the emails
can validate the digital signature using a public key included in a DNS
(Domain Name System) TXT record.
E. VPN
A VPN (Virtual Private Network) is commonly used to create an
encrypted tunnel between two devices or locations. A VPN is not used to
deploy cloud-based networking devices or services
A company needs to purchase a new printer for an open work area. The
primary requirement of this printer is to be as quiet as possible. Which of
these printer types would be the best fit for this requirement?
❍ A. Dot-matrix
❍ B. Inkjet
❍ C. Laser
❍ D. Thermal
The Answer: D. Thermal
Of the available options, thermal printers are the quietest. The only
moving parts in a thermal printer are the motors that push the paper
through the printer, and those motors are small and run almost silently.
The incorrect answers:
A. Dot-matrix
Dot matrix printers are probably the loudest option in this list. The metal
pins in a dot matrix print head are impacting the page, and that printing
process makes a significant amount of noise.
B. Inkjet
An inkjet printer’s printing process is a bit quieter than a dot matrix
printer, but it’s not as quiet as thermal printing. The sound of the carriage
moving the print heads across the page and the printing process itself
would not provide the quietest printing option given the available options.
C. Laser
A laser printer uses many moving parts, high voltages, and a large motor to
print a single page. This process makes more noise than a thermal printer,
so it wouldn’t fit the requirements
