Question 1
Cable Type Pros Cons Application
STP( Shielded
Twisted Pair)
The shielding helps
to protect the signals
which are present on
the cable from
external interferences
(Comer, 2018). It can
support higher
transmission rate.
The potential
performance increase
is not worthy due to
the indulgence of
more cost relating to
other cables. The
installation time of
the cable is also long.
The cable is often
used in data network
for medium and short
length connections.
UTP (Unshielded
Twisted Pair)
The main pros are
related to the easy
installation as they
have smaller overall
diameter.
Prone to EMI
(Electro Magnetic
interferences)
The application is
majorly done in
networking cable
Coaxial cable The cost of the cable
is very much less and
is also less
susceptible to noise
or interferences (EMI
or RFI)
One of the main
concern in the cable
is the security as it
can be easily tapped
by breaking it and
inserting T-joint in
between.
The Coaxial cable is
used in the
transmission line for
the signal relating to
radio transmitter.
SMF (Single Mode The main advantage It can be considered Application is seen in

Fiber) in the sector is related
to the retaining of the
fidelity of each light
pulse over large
distance and exhibit
no dispersion which
is caused by multi-
mode fibers.
as costly as compared
to other cables
(Ahammad, 2018).
Installation factor can
be one of the concern
areas.
long distance
communication with
security factor
included into the
sector.
Question 2
Two commonly used native Linux troubleshooting commands
 Dig: Domain Information Groper
 Telnet: Connects destination host
Troubleshooting command with use
 Traceroute: It is a command which can be used in the network troubleshooting which
would be showing the number of hops which are taken to reach the destination.
 Netstat: It can be implemented in the domain of the identification of routing table
problem and connection info so as to check the overall network.
 DiG (Domain information groper): This command can be used in the sector of
troubleshooting in the DNS related query.
 ARP command: The command can be used in the sector of viewing the security aspect in
the Kernel ARP table.

 Ethtool: This tool can be stated as a replacement of the mii-tool. The command can be
used in the sector of setting of speed and duplex of the network interface.
Question 3
There can be different forms of questions which can be asked in the sector of the detection of the
problem and getting into the severity of the problem (Ma et al., 2016). Some of the common
questions which can be stated in the context are stated below:
 What is the main problem area which is seen in the sector of operation of the network?
 What was the system condition when the problem had occurred?
 Is the connection between the different terminals still exist?
 Is the IP address which is linked to the connection very much secured from different
activity of intruder?
 Is the safety of the data which prevail in the system is taken care off?
