Which of the following is an indication of a faulty cabling installation?

Frequent data disruptions indicate a faulty cabling installation because reliable performance in networking requires stable and continuous data transmission. When a cabling system is installed incorrectly or when there are damaged cables, it can lead to interruptions in data flow. These disruptions can manifest as slow connectivity, packet loss, or erratic performance, affecting the overall functionality of the network.

In contrast, stable signal quality, enhanced transmission efficiency, and consistent performance across different devices typically reflect a well-installed and functioning cabling system. Such characteristics signify that the cables are properly connected and in good condition, allowing for optimal data transmission without interruptions. Therefore, the presence of frequent data disruptions clearly points to issues within the cabling installation.
