Which data-link layer frame type is delivered to all devices on the local network segment?

• A. Unicast frames target a single MAC address.
• B. Multicast frames target a group of devices.
• C. Broadcast frames target all devices on the local network.
• D. Enhanced frames target special management devices.

Answer: (C)

Broadcast frames are used to reach every device on the local network segment. They use the destination MAC address FF:FF:FF:FF:FF:FF, and switches flood these frames out all ports within the same broadcast domain so every device on that LAN sees it. This behavior differs from unicast frames, which are sent to a single MAC address, and multicast frames, which target a specific group of devices that have joined a multicast group. Enhanced frames isn’t a standard term for this purpose. So, the frame type delivered to all devices on the local network is the broadcast frame.
