In a Voice, Data, and Video (VDV) system, issues often arise from the physical infrastructure that supports the connections, making cable the primary source of problems. Cables can suffer from various issues such as poor installation, damage, or degradation over time, which can lead to loss of signal quality, reduced bandwidth, and connectivity failures. Proper cabling is essential for ensuring that the signals for voice, data, and video are transmitted accurately and effectively.

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) can certainly affect the performance of a VDV system, but they typically act on the signals that are transmitted through the cables rather than being the originating cause of problems. While external interference can complicate matters, the integrity and quality of the cables themselves are often the foundational aspect that determines the overall performance and reliability of the system.

Therefore, the correct answer recognizes that the physical cable infrastructure is the first point of potential failure in a VDV system.
