41. What is structured cabling and why should you use it?
ANSWER:
Structured cabling is a standard that specifies how cabling should be installed in a network. It
is based on an extended star physical topology. Network cabling standards are designed to
ensure adherence to standards for equipment rooms and wiring closets, including limitations
on media, which helps limit the possible reasons for network failure or poor performance. If
the network cable plant is in good working order and meets standards, a network
administrator’s job is easier. Structured cabling facilitates troubleshooting as well as network
upgrades and expansion.

ANSWER:
Because 1000BaseT uses all four pairs to transmit and receive, the blue and brown pairs must
also be crossed in addition to the green and orange pairs. 100BaseT only requires the green
and orange pairs to be crossed.

cabling used?
ANSWER:
Network devices connecting with RJ-45 plugs over twisted-pair cabling are classified as
medium dependent interface (MDI) devices or MDI crossed (MDI-X) devices. MDI devices
transmit on pins 1 and 2 and receive on pins 3 and 6. MDI-X devices receive on pins 1 and 2
and transmit on pins 3 and 6. A straight-through cable is used to connect an MDI device to an
MDI-X device and a crossover is used to connect two MDI devices or two MDI-X devices.

Wireless networks can be used to extend your network, whether you need a temporary

are not able to install wiring due to the type of building material. Wireless can be used as a
backup solution. Wireless also allows users to roam.

ANSWER:
Fiber-optic is capable of much higher bandwidths. Fiber-optic cabling is immune to EMI and

almost impervious to eavesdropping. Because of low attenuation, fiber-optic cable can travel
greater distances at a higher bandwidth.
