Why would a Layer 2 switch need an IP address?

  • to enable the switch to be managed remotely
  • to enable the switch to receive frames from attached PCs
  • to enable the switch to send broadcast frames to attached PCs
  • to enable the switch to function as a default gateway
    Answers Explanation & Hints: A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface. Routers, not switches, function as default gateways.
