Total questions: 12
Worksheet time: 6mins
From what metal is wired Ethernet cable made?
aluminum
copper
steel
titanium
Electromagnetic interference on wire Ethernet comes from all of the following EXCEPT:
other wire pairs in the same cable
crosstalk
electrical wiring running parallel and alongside the Ethernet
Bluetooth and wifi radio signals
The gradual loss of signal strength as it travels through cable is called
attenuation
crosstalk
intermodular interference
frequency harmonic
Twisting the pairs of wires at different rates in Ethernet cable minimizes
attenuation
crosstalk
data rates
cable length
The main weakness of unshielded twisted pair (UTP) Ethernet over other Ethernet cables is
it is most susceptible to EMI.
it must be made from steel to keep the cable rigid.
it can only have 3 pairs of wires instead of 4.
it can only be used for cable lengths less than 10 meters.
Which of the following is considered fully shielded cable?
ScTP
S/FTP
F/UTP
F/FTP
UTP
Which Ethernet cable standard is capable of 1 Gbps data rates?
Cat 3
Cat 4
Cat 5
Cat 5e
Which Ethernet cable has a higher data rate?
Fast Ethernet
Gigabit Ethernet
Both have identical data rates and are just made of different metals.
It depends on the type of connector used.
The more widely used RJ-45 connector standard is
DOCSIS 3.0
GG-45
T568A
T568B
The wires connected to Pins 1 & 2 of the T568B standard are
Blue-White/Blue
Brown-White/Brown
Green-White/Green
Orange-White/Orange
You are using a copper Ethernet cable to connect two computers directly together.
Which type of cable would you use to do this?
Auto-MDI/MDIX
crossover
straight-through
Which wire pairs are always in position 7 & 8, regardless if using the T568A or T568B standard?
blue-white/blue
brown-white/brown
green-white/green
orange-white/orange
