21. Which characteristic describes an IPv6 enhancement over

22. What is Ethernet?

23. What is the minimum Ethernet frame size that will not be
discarded by the receiver as a runt frame?

24. What are the characteristics of MAC addresses?

25. What addressing information is recorded by a switch to build
its MAC address table?

26. What are the reasons for physical layer protocols to use
frame encoding techniques?

27. What is the definition of bandwidth?

28. A network administrator notices that some newly installed
Ethernet cabling is carrying corrupt and distorted data signals.
The new cabling was installed in the ceiling close to fluorescent
lights and electrical equipment. Which two factors may interfere
with the copper cabling and result in signal distortion and data

29. What technique is used with UTP cable to help protect
against signal interference from crosstalk?

30. What is one advantage of using fiber optic cabling rather
than copper cabling?


21. IPv6 addresses are based
on 128-bit flat addressing as opposed to
IPv4 which is based on
32-bitaddressing. The IPv6 header is simpler than
the IPv4 header is, which basically improves
packet handling

22.a system for connecting a number of computer systems to form
a local area network, with protocols to control the passing of
information and to avoid simultaneous transmission by two or more

23.The minimum Ethernet frame size is 64 bytes.
Frames smaller than 64 bytes are
considered collision fragments or runt frames and
they are discarded

24. They are only routable within the private network and They
have a 32-bit binary value

25.A switch builds a MAC address
by inspecting incoming Layer 2 frames and
recording the source MAC address
found in the frame header. The
discovered and recorded MAC address is then
associated with the port used to receive
the frame

26.To provide better media error correction and to identify
where the frame starts and ends.

27 it is basically a particular range of frequency with in a
band used for transmitting signals

28.These distortions usually come from radio waves and
electromagnetic devices such as motors and florescent lights.
Crosstalk is a disturbance that is caused by adjacent wires bundled
too close together with the magnetic field of one wire affecting
another. Signal attenuation is caused when an electrical signal
begins to deteriorate over the length of a copper cable.

29.To help prevent the effects of crosstalk, UTP cable wires are
twisted together into pairs. Twisting the wires together causes the
magnetic fields of each wire to cancel each other out.

30. Fiber optic cables have a core that carries light to
transmit data. This allows fiber optic cables to carry signals at
speeds that are only about 31 percent slower than the speed of
light—faster than Cat5 or Cat6 copper cables. There is also less
signal degradation with fiber cables.

i hope you like my answer please give a thumbsup happy to help
thank you
