A hotspot provides a redundant internet connection using cellular data. This ensures connectivity for the meeting even if the primary ISP connection fails. * Why Not A (Wireless access point): A wireless access point expands Wi-Fi connectivity but does not provide internet redundancy. * Why Not B (Near-field communication): NFC is used for short-range communication, not internet connectivity. * Why Not D (Bluetooth): Bluetooth is for short-range device pairing and cannot serve as a backup internet connection. CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, internet connection types and redundancy.
