possible.
A network connection in a conference room was installed years ago, and
there’s no documentation for the cable run. Connecting a device to the
cable results in a successful Ethernet connection, so the other end of
the cable should terminate somewhere in the wiring closet. Which of
these tools would be the best choice to find the other end of the network
connection?
❍ A. Cable tester
❍ B. Tone generator
❍ C. Multimeter
❍ D. Crimper
The Answer: B. Tone generator
A tone generator is used to produce an analog tone on the cable, and an
inductive probe is used to “listen” for the tone on the other end of the
cable.
A client’s laptop has recently had its internal mini-PCIe wireless adapter
card replaced. Although Device Manager shows the card working
properly, the wireless card management software shows very low signal
strength. The wireless card keeps dropping its wireless connection and
will not maintain a consistent network link. What is the most likely
reason for this problem?
❍ A. The mini-PCIe card isn’t compatible with the laptop
❍ B. The wireless adapter antenna cable isn’t connected
❍ C. The operating system doesn’t support the wireless card
❍ D. The wireless card is administratively powered off
The Answer: B. The wireless adapter antenna cable isn’t connected
The antenna cable connectors are very small, and it’s easy to leave them
disconnected after working inside of a laptop. A missing antenna cable
will cause the wireless signal strength to be very low, and often there’s not
enough signal strength to reliably send or receive data.
A user has powered on their computer and received the message
“Operating system not found.” A check of the system shows that the hard
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.
A user is having an issue with a smartphone not recognizing their
location on a map. All other Internet and phone features are working

visible but it’s too faint to clearly see anything. What is the MOST likely
cause of this issue?
❍ A. Video card
❍ B. Inverter
❍ C. Video driver
❍ D. Power adapter
The Answer: B. Inverter
The inverter powers the CCFL (Cold Cathode Fluorescent Lamp) LCD
(Liquid Crystal Display) backlight, allowing you to easily view the pixels
on the display. Most newer laptops will use LED (Light Emitting Diode)
backlights that use the existing DC (Direct Current) power and don’t
require an inverter.
A graphics designer is experiencing increasing delays when accessing files
on her hard drive. The user maintains a daily backup of all data on the
drive. Which of these would be the BEST next troubleshooting step for
this issue?
❍ A. Reinstall Windows
❍ B. Perform a hard drive diagnostic
❍ C. Restore from the daily backup
❍ D. Boot to Safe Mode
The Answer: B. Perform a hard drive diagnostic
Before making any changes, it would be useful to gather more information
about this problem. A hardware diagnostic would determine if the hard
drive itself is working properly. If the hard drive is operating normally, the
troubleshooting process can then shift to the operating system
and software.

The Answer: A. Document archive
The DVD-ROM (Digital Versatile Disc - Read Only Memory) format
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 DVD-ROM optical discs.
When a user starts their computer, the screen remains blank and the
computer beeps twice. Which of these would be the MOST likely cause
of this issue?
❍ A. The boot device is not connected
❍ B. The memory is faulty
❍ C. The operating system has become corrupted
❍ D. The PC is infected with malware
The Answer: B. The memory is faulty
The POST (Power On Self Test) is the initial hardware check that occurs
during the startup process. If a major hardware component is faulty, the
computer will beep and a message will be displayed on the screen. If the
issue is related to a critical component, the computer will not be able to
display a message on the screen and instead will beep a certain number of
times as a code to specify the error.

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 stylus on a Windows tablet will no longer interact with the user
interface. Which of these would be the MOST likely cause of this issue?
❍ A. Digitizer
❍ B. Backlight
❍ C. Antennas
❍ D. Inverter
The Answer: A. Digitizer
The digitizer is the component in a touch screen that converts the
analog input from a fingerprint or stylus into a digital input that can
be understood by the computer. If the digitizer is having an issue, then
problems will occur with any direct screen input.

computer. Using a docking station is a common solution that provides
many different interfaces, and often includes the ability to install a fullsize PCI Express (Peripheral Component Interconnect Express) adapter.
A USB (Universal Serial Bus) to Ethernet adapter is a simpler solution
that only provides an Ethernet interface, but it’s much more portable than
a docking station.
A server administrator has received an alert showing that one drive in a
RAID 1 array has failed. Which of the following would be the best way
to resolve this alert?
❍ A. Replace the bad drive and resync the array
❍ B. Replace all drives in the array and resync the array
❍ C. Replace the bad drive and restore from backup
❍ D. Convert the array to RAID 0 and replace the drive
❍ E. Replace all drives in the array and restore from backup
The Answer: A. Replace the bad drive and resync the array
A RAID 1 (Redundant Array of Independent Disks, level 1) array is a
mirrored array, which means that all of the information on one physical
drive is also copied and maintained on a separate drive. If one drive fails,
then the drive with the redundant data continues to be available. To
repair the array, the bad drive needs to be replaced and the data from the
redundant drive is synchronized to the new drive.

building a gaming computer. Many computer games also read extensively
from storage, so the speed of an SSD (Solid State Drive) will provide the
fastest possible data access.
What type of device connects multiple computers to the network, but
becomes less efficient as network traffic increases?
❍ A. Switch
❍ B. Hub
❍ C. Repeater
❍ D. Router
The Answer: B. Hub
A hub operates as a multi-port repeater, where incoming traffic is repeated
to every other port in the hub. If more than one device attempts to do this
at the same time, these conflicting signals are called a collision. Each time
a collision occurs, the sending devices have to stop transmitting, wait a
random amount of time, and try sending traffic again. If many devices are
sending large amounts of data, the overall network efficiency will decrease
as the number of collisions increase.

A network administrator would like to enable DHCP on a laptop, but he
would like the same IP address to be assigned to the laptop each time it
starts. Which of the following would provide this functionality?
❍ A. Create an IP reservation on the DHCP server
❍ B. Administratively configure the laptop’s MAC address
❍ C. Use APIPA addressing
❍ D. Assign the laptop to a static IP VLAN
The Answer: A. Create an IP reservation on the DHCP server
A DHCP (Dynamic Host Configuration Protocol) server will
automatically assign IP (Internet Protocol) addresses to devices on the
network from an available pool. This means that the IP address for a
device may change over time based on the IP addresses that are currently
available in the pool. To force the same IP address assignment each time,
the network administrator can create an IP reservation in the DHCP
server that will associate a specific IP address to the MAC (Media Access
Control) address of the laptop.
A user is complaining about slow network performance from their
workstation. A network technician checks the data closet and finds

❍ C. Punch-down tool
❍ D. Cable tester
The Answer: C. Punch-down tool
A punch-down tool is used to firmly “punch” a wire into a wiring block,
such as a 110 block. These blocks are usually located in a wiring closet or
on the back of a patch panel.
A user has just connected to a new wireless network, but they cannot view
any Internet web sites. Their network configuration shows the IP address
as 169.254.228.109, the subnet mask is 255.255.0.0, and they have not
been assigned a default gateway. Which of these is the MOST likely
cause of this issue?
❍ A. The subnet mask is not correct
❍ B. The Internet provider is experiencing a temporary outage
❍ C. The DHCP server is down
❍ D. The wireless adapter is not working properly
The Answer: C. The DHCP server is down
If a DHCP (Dynamic Host Configuration Protocol) server is not
responding, then the local workstation will configure itself with an
APIPA (Automatic Private IP Addressing) address. The usable APIPA
addresses are in the range between 169.254.1.0 through 169.254.254.255.
An APIPA address is a link-local address, so network communication is
limited to the local IP subnet.
. A help desk technician needs to use different Windows versions to
study for an industry certification exam. The technician currently uses
a Windows desktop computer with 4 GB of RAM and a 750 GB free
on the hard drive. Which of the following would be the BEST way to
perform this task? (Choose TWO)
❍ A. Install a KVM
❍ B. Install an additional hard drive
❍ C. Create a Windows Recovery Environment boot drive
❍ D. Upgrade the system RAM
❍ E. Install Windows guest VMs
The Answer: D. Upgrade the system RAM, and
E. Install Windows guest VMs
The easiest way to use multiple operating systems on a single machine
is to run them as virtual machines. Although there’s plenty of storage
space for multiple virtual machines, the 4 GB (Gigabytes) of RAM
(Random Access Memory) on the host computer is too small to support
multiple Windows operating systems at the same time. Once the memory
upgrade is complete, it’s a relatively easy process to install the guest virtual
machines on the existing hard drive.
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 the local 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.
Which of the following BEST describes a Bluetooth network? ❍ A. PAN ❍ B. WAN ❍ C. LAN ❍ D. MAN
The Answer: A. PAN
A PAN (Personal Area Network) is designed for a small area and usually

❍ C. Disassemble the laptop case and document the process
❍ D. View the Bluetooth information in Network settings
The Answer: C. Disassemble the laptop case and document the process
Although the operating system driver can sometimes provide details about
what’s inside, they often can hide details about the specific hardware. The
only way to know the exact make and model of the Bluetooth adapter is
a physical examination. Some laptops are easier to open than others, so
it’s useful to document the process used to gain access to the Bluetooth
hardware.
A server administrator has been asked to configure the storage
requirements for a new database server. The database owner requires the
fastest performance, and redundancy if a single drive fails. The storage
array should support 8 TB or larger of available space. Which of the
