CompTIA Network+ (N10-007) — Question 598

Which of the following technologies is MOST likely used to provide connectivity to multiple IoT devices within a room without access to the WLAN?

Answer options

• A. IR
• B. 802.11
• C. Bluetooth
• D. NFC

Correct answer: C

Explanation

Bluetooth is designed for short-range communication and can connect multiple IoT devices without needing a WLAN. In contrast, IR requires line-of-sight, 802.11 relies on a wireless network, and NFC is suitable for very short-range interactions, making them less ideal for connecting multiple devices in this scenario.
