CompTIA A+ Core 1 (220-1001) — Question 371

Which of the following network devices is used to forward data from one device to another device on the same LAN?

Answer options

• A. Switch
• B. Router
• C. Hub
• D. Modem
• E. Bridge

Correct answer: A

Explanation

The correct answer is A, Switch, as it is specifically designed to connect devices on a LAN and forward data between them based on MAC addresses. A Router (B) operates at a different layer and is used to connect different networks, while a Hub (C) simply broadcasts data to all devices without any filtering. A Modem (D) connects to the internet and is not used for LAN data forwarding, and a Bridge (E) connects two segments of a network but is less common than switches for this purpose.
