STRUCTURED CABLING FINAL EXAM STUDY
GUIDE 2026/2027 | LATEST QUESTIONS &
ANSWERS
Twisted Pair Cable - correct answer-Cables made of copper wires that are twisted
around each other and are surrounded by a plastic jacket (such as traditional
home phone wire).
Unshielded Twisted Pair (UTP) - correct answer-Networking cable that has four
twisted pairs of copper wire and a flexible outer coating.
Category 5 - correct answer-What is the minimum category of twisted-pair cable
you need to support 100 Mbps?
Category 5e - correct answer-A popular category of twisted pair that supports
speeds up to 100 Mbps. It is now the minimum recognized cable category for data
transmission in ANSI/TIA-568-C.
Category 6 - correct answer-A popular category of twisted pair that supports
speeds up to 1000 Mbps. Its intended use is for Gigabit Ethernet and other future
high-speed transmission rates.
, Category 6a - correct answer-Was officially recognized with the publication of
ANSI/TIA/EIA-568-B.2-10 in February 2008. In addition to more stringent
performance requirement it also extends the usable bandwidth to 500MHz.
Dark Fiber - correct answer-A spare fiber installed during the construction of the
network that was reserved for future use.
Single Mode Fiber Optic Cable - correct answer-A form of fiber-optic cable that
supports only one signal transmission at a time and that is used mainly for long-
distance communication.
Multimode Fiber Optic Cable - correct answer-Used for shorter distances this type
of fiber-optic cable can carry several signals at the same time.
Plenum Cable - correct answer-Fire resistant and non-toxic; it must be used when
wiring above ceiling tiles. This grade of cable does not give off noxious or
poisonous gases when burned.
Riser Cable - correct answer-Another term for vertical cable; refers to cable that
goes between floors in a building.
Bandwidth - correct answer-The amount of data that can be transmitted over a
network in a given amount of time.
Decibel - correct answer-A unit used to compare the loudness of different sounds.
Propagation Delay - correct answer-Any delay in communications due to signal
transmission time through a physical medium
