CompTIA A+ Core 1 (220-1101) — Question 145

A technician is working to connect an RS-232 serial signature pad to a customer's ultralightweight laptop. Which of the following should the technician use to install the device?

Answer options

• A. Port replicator
• B. Wi-Fi Direct
• C. Hotspot
• D. USB-C cable

Correct answer: A

Explanation

The correct answer is A, as a port replicator offers the necessary ports to connect an RS-232 device to a laptop that may not have the appropriate serial port. The other options, such as Wi-Fi Direct and Hotspot, are wireless solutions that do not cater to RS-232 connections, while a USB-C cable is not compatible with RS-232 devices without an adapter.
