220-1102 Question #429: Real Exam Question with Answer & Explanation

Question

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?

Options

• ASAN
• BLAN
• CGPU
• DPAN

Explanation

Equipping all classrooms with high-definition IP videoconferencing equipment will significantly impact the university's Local Area Network (LAN) due to increased bandwidth demands.

Common mistakes.

• A. 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.
• C. 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.
• D. 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.
