What are characteristics of a UTP Ethernet cable?

A UTP (Unshielded Twisted Pair) Ethernet cable is designed with a specific configuration that helps in minimizing electromagnetic interference, making it effective for data transmission. Its twisted pairs reduce crosstalk and external interference, contributing to a relatively low susceptibility to noise.

The correct choice, highlighting high noise and lower costs, indicates that UTP cables, while generally cost-effective, can still be more vulnerable to external interference compared to more advanced cabling options, such as shielded twisted pair (STP) cables or fiber optics. UTP cables are often chosen for their affordability and sufficient performance in many networking environments, despite their limitations regarding noise handling. This balance of cost-effectiveness and moderate susceptibility to noise makes UTP a popular choice for everyday networking applications.

The other options do not accurately reflect the common characteristics or use cases of UTP cables. For instance, the mention of "high noise and higher costs" or "less susceptible to noise" does not align with the well-established understanding of UTP cables, which are known for being economical while still providing adequate performance in standard environments.
