CompTIA A+ Core 1 (220-1201) — Question 104

An IT specialist compares Bluetooth and NFC technologies for mobile device connectivity. Which of the following statements accurately describes a key difference between the two?

Answer options

• A. NFC is faster than Bluetooth when transferring large files between devices.
• B. NFC consumes more power than Bluetooth, making it less suitable for devices in which battery conservation is crucial.
• C. NFC requires pairing with the receiving host, whereas Bluetooth just needs the available connection.
• D. NFC works best within a few centimeters, but Bluetooth can connect devices that are up to 32ft (10m) apart.

Correct answer: D

Explanation

The correct answer is D because NFC operates effectively over very short distances, typically just a few centimeters, while Bluetooth can connect devices at much greater distances, up to 32 feet (10 meters). Option A is incorrect as Bluetooth is generally faster for larger file transfers. Option B is not accurate because NFC typically consumes less power than Bluetooth, making it more suitable for battery-sensitive applications. Option C is wrong since NFC does not require pairing in the same way Bluetooth does; it uses a simpler activation method.
