Correct Answers
A hardware technician replaces the central processing unit (CPU) on an Advanced
Micro Devices (AMD) motherboard. What must be applied when connecting the
heat sink to the CPU? - (ANSWER)During the installation of the heat sink on top
of the CPU, a small amount of thermal grease must be applied in an X-pattern to
allow for heat transference to be most successful.
A college campus is spread throughout an entire city. There is a plan to upgrade
the connectivity to all buildings for increased speed. What type do engineers
upgrade to? - (ANSWER)A metropolitan area network (MAN) refers to a specific
network type covering an area equivalent to a city or other municipality. The
upgraded campus network will be this type of network.
A user complains about the quality of the display on a laptop. The user mentions
that the laptop has been in use since the company started many years ago. IT
determines that the display uses a very early thin film transistor (TFT) technology
and will replace the laptop. Which TFT technology does the display use? -
(ANSWER)In an early TFT implementation, twisted nematic (TN) crystals twist or
untwist in response to the voltage level. This is the earliest type of TFT technology
that can be in budget displays.
A technician follows a best practice methodology while troubleshooting a
problematic computer system. Which of the following options is a consequence of
having a problematic computer when considering that problems have causes,
symptoms, and consequences? - (ANSWER)It is important to realize that
problems have causes, symptoms, and consequences. A consequence is the result
, 2
of the problem. Not being able to provide data is a consequence of having a
problematic system.
A systems administrator is wanting to use a process in which the TCP/IP protocol
is used to query and update an X.500 directory. What can be used to accomplish
this task? - (ANSWER)The Lightweight Directory Access Protocol (LDAP) is a
TCP/IP protocol used to query and update an X.500 directory. LDAP uses TCP and
UDP port 389 by default.
A company plans on live streaming a company-wide meeting once a month.
Engineers prepare network equipment to allow the traffic. Which protocol is
normally used for such a task? - (ANSWER)The User Datagram Protocol (UDP)
provides unreliable, connectionless forwarding. UDP has less transmission
overhead than TCP and is the protocol used with audio and video streams.
A technician installs memory into a computer that supports a multi-channel
configuration. A 4GB module is placed in bank A1 and a 12GB module is placed in
bank B1. A diagnostic tool reports that 16GB is useable, but not as multi-channel.
What mode does the system use in making all of the memory available? -
(ANSWER)In a modern system with a dual-channel memory controller, there are
two 64-bit pathways through the bus to the CPU. This means that 128 bits of data
can be sent per transfer.
An organization conducts a weekly video conference from its home office to its
field locations. Recently, employees at the field locations have been complaining
of poor audio and video quality. Which protocol does an engineer monitor for
performance issues? - (ANSWER)The User Datagram Protocol (UDP) is an
unreliable, connectionless protocol. It is used in time-sensitive applications, such
as audio or video. Lost data results in poor audio and video streaming.

Several users of a shared printer complain that the printer is printing on both
sides of a sheet of paper when it should only print on one side. What setting does
a technician change? - (ANSWER)Duplex printing refers to the capability of a
printer to print on both sides of a sheet of paper. The technician would adjust this
setting to single-sided printing.
What issue does the help desk technician suspect is causing a problem of a cursor
moving on its own? - (ANSWER)On a laptop, if touchpad sensitivity is too high,
typing can cause vibrations that move the cursor. Examples include the pointer
drifting across the screen without any input or a "ghost cursor" jumping about
when typing. Calibrating the touchpad is a recommended solution.
An engineer plans a new wired infrastructure rollout that will support wireless
capabilities. For this rollout, the cable length is approximately 328 feet and
includes the incorporation of access points that supplies 48V of power around 13
watts. Which specific IEEE standard does the engineer implement? -
(ANSWER)The 802.3af standard allows powered devices to draw up to about 13
W. Power is supplied as 350mA@48V and limited to 15.4 W. Usable wattage
usually falls around 13 W
A security team at a company discovers that malware is moving from one guest
OS to another VM in attempts to interact with the hypervisor. What security issue
is occurring?
A.Escape - (ANSWER)Virtual machine escaping (VM escaping) refers to malware
running on a guest OS jumping to another guest or to the host system itself.
