Question

A workstation sends a unicast frame to a server on the same VLAN. The Layer 2 switch has just been powered on and its MAC address table is empty. What does the switch do with this frame?

Accepted Answer

It floods the frame out all ports in the same VLAN except the port on which it was received

Answer

It drops the frame because the destination MAC address is not in the MAC address table

Answer

It forwards the frame only to the default gateway for Layer 3 resolution

Answer

It buffers the frame until an ARP reply populates the MAC address table
