Question 9

Which standards were developed to define industry-standard pinouts and
color coding for twisted-pair cabling? (Choose two.)
a. CWDM
b. TIA/EIA-568A
c. DWDM

Answer 9

Answer: b, d. To define industry-standard pinouts and color coding for
twisted-pair cabling, the TIA/EIA-568 standard was developed. The first
iteration of the TIA/EIA-568 standard has come to be known as the TIA/
EIA-568A standard, and since then, an updated standard called TIA/EIA-568B
has been released. TIA/EIA-568B is the more commonly used standard in the
United States today.
