CompTIA Network+ (N10-007) — Question 621

Which of the following devices acts as a multiport repeater at the physical layer of the OSI model?

Answer options

• A. Switch
• B. Bridge
• C. Hub
• D. Transceiver

Correct answer: C

Explanation

The correct answer is C, Hub, as it operates at the physical layer and can connect multiple devices, repeating signals to all ports. A switch and a bridge operate at the data link layer, making them unsuitable for the role of a multiport repeater. A transceiver is a device that can send and receive signals, but it does not function as a multiport repeater.
