The wire colors used in 4-pair UTP cables are ___.

The correct answer identifies the standard color coding for wires in 4-pair Unshielded Twisted Pair (UTP) cables. In telecommunication and networking, 4-pair UTP cables typically follow a color coding scheme to ensure consistent wiring that allows for proper signal transmission. The standard color sequence for the pairs of wires within these cables is blue with a white stripe, orange with a white stripe, green with a white stripe, and brown with a white stripe. This leads to the association of the colors in the pairs as blue, orange, green, and brown.

When installed according to this color code, the wiring facilitates easy identification and troubleshooting, ensuring that each color can be properly paired, hence contributing to a reliable network setup. This systematic approach is crucial for any electrical or networking work where top-notch performance and minimal errors are desired.

Alternatives provided do not match the recognized wiring convention for UTP cables, thus illustrating the importance of knowing standardized practices within electrical and networking fields.
