What are two characteristics of Ethernet MAC addresses? (Choose two.)
They are globally unique.
MAC addresses use a flexible hierarchical structure.
MAC addresses must be unique for both Ethernet and serial interfaces on a device.
They are routable on the Internet.
They are expressed as 12 hexadecimal digits.

If a device receives an Ethernet frame of 60 bytes, what will it do?
drop the frame
process the frame as it is
send an error message to the sending device
add random data bytes to make it 64 bytes long and then forward it
Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on? (Choose two.)

The source address in the frame is a multicast address.
The destination address in the frame is a known unicast address.
The destination address is unknown to the switch.
The source address in the frame header is the broadcast address.
