CompTIA A+ Core 1 (220-1001) — Question 140

Which of the following devices can be used to connect multiple devices within a network without broadcasting to every network port?

Answer options

• A. Unmanaged switch
• B. Hub
• C. Firewall
• D. Cable modem

Correct answer: A

Explanation

The correct answer is A, as an unmanaged switch efficiently connects multiple devices on a network by sending data only to the intended recipient port, unlike a hub, which broadcasts to all ports. A firewall serves to filter traffic for security purposes and a cable modem is used for internet connectivity, neither of which are designed for connecting multiple devices within a local network.
