CompTIA A+ Core 1 (220-1201) — Question 183

A user ran out of USB ports on their laptop but would like to plug in more devices. Which of the following technologies is the best for them to use?

Answer options

• A. Near-field communication
• B. Bluetooth
• C. USB receiver
• D. Port replicator

Correct answer: D

Explanation

The best solution in this scenario is a Port replicator, as it allows multiple USB devices to be connected through a single port. Near-field communication and Bluetooth are more suitable for wireless connections but do not expand USB ports. A USB receiver typically refers to a device for connecting a single peripheral, which does not address the need for more ports.
