CompTIA Network + Final Practice Exam Cert Master
While performing a Recovery point objective
resiliency test for availability,
a technician is trying to
calculate the amount of data
that a system can sustain, and
further calculate the time it
would take for a database to
be recovered if it was
targeted by a virus. What is
the technician testing for?
A network security practitioner Control Plane
is hardening a corporate
network to mitigate the risk
from route processor
vulnerabilities. Which quality
of service (QoS) stack
operational layer comprises
of traffic that keeps the
network itself operational,
including routing updates, ARP
traffic, STP notifications, NTP
updates, QoS classification
and link
reservation requests?
,The network security office is Multi-Factor
tasked with updating
authentication requirements
for computer access as it
currently uses a single sign-
on and password. The office
determines that it will begin
using the sign- on criteria but
add an additional
requirement of a code being
sent to the employee's
personal cell phone to grant
authorization to complete
access requirements for login.
What is the name of this
authentication?
A military installation is Straight Tip (ST)
upgrading its network
infrastructure. Which fiber
optic connector type
developed by AT&T used to
be very common for multimode
networks in commercial or
military installations due to
its quick-connecting
bayonet, but is no longer
considered standard when
retrofitting?
A network engineer is The legacy devices do not support fragmentation
troubleshooting a packet
loss issue on a small
corporate Internet of Things
(IoT) network. The issue began
occurring after a legacy
device was added to the
network, and the engineer has
noted that the MTU size on the
,router is less than the default
1500, at 750 MTU. Propose a
likely cause of the packet
loss by the legacy devices.
A network engineer is Active test access point (TAP)
performing packet capture
on a Gigabit copper cable
for analysis and
troubleshooting of a large
network. The engineer requires
all frames to be captured
(including frames with errors),
performs signal regeneration,
and is easy to implement with
dedicated hardware.
Suggest a network sniffer that
will fulfill the engineer's
requirements.
A network technician is using Time To Live (TTL) header field
traceroute on a corporate
network to make use of
ICMP "Time Exceeded" in order
to identify routers along a
delivery path. Determine
the TCP/IP feature that
traceroute uses to
accomplish this.
, A network engineer is Ensure IGMP snooping is enabled at the switch
configuring an Internet of
Things (IoT) network that uses
multicasting to allow
devices to communicate
over a VLAN-enabled
managed switch. An issue is
occurring where the multicast
traffic is being flooded across
the network as a broadcast,
resulting in reduced network
performance. Recommend a
potential fix for this issue.
A network consultant is Temperature
asked to install Humidity
environmental sensors on Electrical
the organizations' server to
monitor conditions within the
server chassis. Which of the
following factors need
monitoring? (Select all that
apply.)
A network engineer is 2 Two routers count as two hops. Switches do not count as hops.
tracing network routes and
counting network hops. The
engineers ping packet
passes through a total of 3
switches and two routers
before reaching its target.
Determine how many
network hops the packet has
taken. The TTL is set to 64.
A data center network Multiprotocol Label Switching (MPLS) with Shortest Path Bridging (SPB)
administrator working for a
