Definition Questions and Answers 2024/2025
Hub - correct answer Layer 1 device takes the data packets from the router, and sends
them to all the devices connected on the network.
UTP Cables - correct answer These cables are created when pairs of wires are twisted
around each other to protect and cancel out interference from each other and outside
sources
Cat3 - correct answer supports up to 10 Mbps (Megabits per second) for up to 100
meters and is commonly used for phone lines today.
Cat4 - correct answer supports 16 Mbps for up to 100 meters and is not commonly
used today.
Cat5 - correct answer is used in Ethernet lans containing two twisted pairs allowing for
up to 100 Mbps up to 100 meters between the device and the switch, hub, or router.
This has been practically replaced by the Cat5e specification.
Cat5e - correct answer doubles the number of twisted pairs to four for up to 1 Gbps
(Gigabits per second) over up to 100 meters.
Cat6 - correct answer is also used in Ethernet lans and data centers. Is made up of
four tightly woven twisted pairs (more twists per linear foot) and supports 1 Gbps for up
to 100 meters or 10 Gbps for up to 55 meters.
Cat6a - correct answer is an improvement of the Cat6 standard, supporting the same
standards and lengths (with the ability to run 10 Gbps over 100 meters maximum), but
using a higher quality cable that is more resistant to interference. This is most
commonly used in wired networks today.
, RJ11 - correct answer A connector that supports two pairs of wires (four total); typically
used in telephones.
RJ45 - correct answer This is an end connector typically used with Ethernet cables
and supports four pairs (eight wires).
Coaxial cables - correct answer analog cables made of copper but specifically
engineered with a metal shield intended to block signal interference.
Coaxial cables - correct answer are mostly used by cable TV companies to connect
their customers to the company's facilities.
Fiber cables, or fiber-optic cables - correct answer use glass or plastic threads within
cables to transfer the data using light (lasers or leds) as opposed to traditional metal
cables using electricity.
Single-mode cables - correct answer made up of one single glass or plastic fiber. The
benefit of a single fiber cable is the ability to carry higher bandwidth for 50 times the
distance of a multimode cable. This requires higher cost electronics to create the light
and thus is typically used for longer distances (hundreds or thousands of kilometers)
and higher bandwidth applications.
Multimode cables - correct answer wider in diameter due to light modes being sent
across the cable. Multimode fibers are highly effective over medium distances (500
meters or less at higher speeds) and are generally used within a LAN. They are also
less expensive than single-mode fiber due to the potential for use with leds and other
lower-cost options for creating the light.
Ping - correct answer one of the most basic tools for testing connectivity to other hosts
useful in troubleshooting connectivity with other devices
Traceroute/tracert - correct answer used to trace the route an IP packet takes to a
destination isplays each hop (next router) in a numerical list with the hop's IP address
and the time it takes to receive the packet
