    3. FFFF.FFFF.FFFF
    4. 255.255.255.255
    FFFF.FFFF.FFFF (11111111. 11111111. 11111111. 11111111. 11111111. 11111111/2)
  14. Question 14: Which address is used by SWITCH when deciding which port to send data to?
    1. Destination MAC address
    2. Source MAC address
    3. Subnetwork address
    4. Network address
  15. Ques 15: A subnet of Class C borrows 5 bits to divide Subnet, then SubnetMask will be:
    1. 55.255.255.1
    2. 255.255.224.0
    3. 255.255.255.128
