2.1 Wire Ethernet

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
