CompTIA A+ Core 1 (220-1001) — Question 60

A technician needs to give users the ability to transfer files between mobile devices. The technician teaches the staff how to use a file transfer method in which the devices need to be in close proximity with line-of-sight access to each other. Which of the following technologies is the technician teaching to the staff?

Answer options

Correct answer: A

Explanation

The correct answer is A, IR, as it requires devices to be in close proximity with a direct line of sight to function. Bluetooth and NFC can transfer files without requiring a line of sight, while tethering is a method for sharing an internet connection, not for file transfers.
