A large university wants to equip all classrooms with high-definition IP videoconferencing equipment. Which of the following would most likely be impacted in this situation?

A SAN (Storage Area Network) is primarily for centralized storage access and would not be directly impacted by the real-time, streaming nature of videoconferencing unless the videoconferencing system extensively records and archives to a SAN.

High-definition IP videoconferencing generates substantial network traffic, especially when deployed across many classrooms simultaneously. All this traffic would traverse the university's internal LAN infrastructure, placing significant demands on its bandwidth, switches, and cabling, potentially requiring upgrades to ensure quality of service and prevent congestion.

A GPU (Graphics Processing Unit) is a component within a computer that renders graphics; while important for the performance of individual videoconferencing endpoints, it is not a network infrastructure component impacted at the university level.

A PAN (Personal Area Network) is a small network centered around an individual (e.g., Bluetooth devices) and would not be relevant for large-scale classroom videoconferencing infrastructure.
