CompTIA Network+ (N10-008) — Question 598

A network technician added a new workstation to the network and needs to make a custom, shielded cable that is 492ft (150m) with both ends wired to TIA/EIA-568A standards. The workstation is not establishing a link to the switchport. Which of the following is the cause of the issue?

Answer options

• A. Cable shielding
• B. Attenuation
• C. Incorrect pinout
• D. Near-end crosstalk

Correct answer: B

Explanation

The correct answer is B, as attenuation refers to the loss of signal strength over long distances, which can be significant at 492ft. While cable shielding (A) helps reduce interference, incorrect pinout (C) would typically lead to a total failure of the connection, and near-end crosstalk (D) is less likely to be the primary cause in this scenario.
