A switch receives a frame with destination MAC 01:00:5e:00:00:05. The switch's MAC address table does not contain this MAC. How does the switch forward the frame?

It floods the frame out of all ports in the VLAN except the ingress port.

It drops the frame because multicast frames are not forwarded.

It forwards the frame only to ports that have hosts subscribed to the multicast group.

It forwards the frame to the router for multicast routing.

How does an Ethernet switch decide which port to use to forward a unicast frame?

It uses the source MAC address to determine the outgoing port

It looks up the destination MAC address in its MAC address table

It floods the frame out all ports except the ingress port

It forwards the frame out all ports in the same VLAN

A host sends an Ethernet frame to another host on the same switch. The destination MAC address is 00:1c:73:aa:bb:cc. How does the switch determine which port to forward the frame to?

It uses the destination IP address to determine the output port.

It looks up the destination MAC in its MAC address table and forwards the frame out the associated port.

It floods the frame out of all ports to ensure delivery.

It drops the frame because the destination is on the same switch.
