CompTIA A+ Core 1 (220-1001) — Question 289

Which of the following devices performs forwarding decisions based on MAC addresses?

Answer options

• A. Switch
• B. Router
• C. Hub
• D. Repeater

Correct answer: A

Explanation

A Switch is designed to forward data based on MAC addresses, allowing it to efficiently direct traffic within a local network. A Router, on the other hand, makes forwarding decisions based on IP addresses. A Hub simply broadcasts data to all ports without any filtering, and a Repeater amplifies signals without making any forwarding decisions.
