make heads or tails of most of the packets. Which of the following
traffic would they be able to read without private keys?
-Port 110
What tool can be used to test ethernet cabling?
,-Wire map
A network consultant is installing Ethernet to a hub in the control
room. When Ethernet is wired with a hub, there needs to be a means
,of distinguishing the interface on an end system with the interface
on an intermediate system. What is the name of the end system
interface?
-MDI-X
What step of the CompTIA Network+ troubleshooting methodology
involves confirming a theory and determining the next steps to
resolve a problem?
-3
An IT engineer uses the Nmap utility to document a network. The
documentation will then help the engineer plan network
improvements. Which of the following describes the use of Nmap for
this purpose?
-Systems hardening
A cyber consultant examines the security of the control room and
evaluates the organization's maturing level and its use of
security policy and controls. What is the name of this
assessment?
-Posture assessment
A network administrator is researching network virtualization and is
trying to find a standard architecture for appliances to be developed
against. Which of these should the administrator look at for a
standard?
-NFV
A network professional is installing software onto every company
computer and phone that requires several layers of protection for
authentication. What is this called?
-Multifactor
A network consultant is conducting a test to determine the amount
of data transferred through a connection over a given period. What
is the consultant testing?
-Bandwidth
The physical security department of a bank wants to require
employees to authenticate through a locked barrier before accessing
the sensitive areas of the building, such as the IT department. If
, implemented, which of the following will best help regulate such
physical access? (Select all that apply.)
-Biometric Device
-Smart Badge
After a site survey, the network technician found the single wireless
2.4 gigahertz (Ghz) access point (AP) in a large office floor space
does not have a strong enough signal, and is contending a
significant amount of background noise and interference. What will
these findings most likely limit on the AP's wireless signal?
-They will limit the signal's range.
A multi-tenant third-party cloud service that is available via the
Internet can be described as which of the following cloud delivery
models?
-Public
A communications company uses TIA/EIA IS-95 handsets that require
each subscriber to use a code to key the modulation of their signal.
The receiver uses this "key" to extract the subscriber's traffic from
the radio signal. What type of handsets is the company using?
-CDMA
A network port does not seem to be working properly. Which of the
following tools can be used to test if the the port is sending out
data?
-Loopback plug
A computer technician is reading archived logs and identifies that
the company was using 802.11n. Not knowing what this Wi-Fi
category meant, the technician researched its origins. In recent
years, what was 802.11n renamed?
-Wi-Fi 4
Engineers survey a newly acquired set of buildings as part of an
organizational acquisition. The facilities are a few hundred yards
from one another. On-site IT staff state a fiber connection between
the buildings, but it has been very unreliable and often does not
