  1. Unable to Ping Default Gateway
  3. If an Ethernet port on a router were assigned an IP address of, what would be the valid subnet address of this host?
  4. Subnet Mask
  5. Why subnet?
  1. a /28 is The fourth octet is a block size of 16. Just count by 16s until you pass 37. 0, 16, 32, 48. The host is in the 32 subnet, with a broadcast address of 47. Valid hosts 33-46
  2. b A /25 mask is Used with a Class B network, the third and fourth octets are used for subnetting with a total of 9 subnet bits, 8 bits in the third octet and 1 bit in the fourth octet. Since there is only 1 bit in the fourth octet, the bit is either off or on—which is a value of 0 or 128. The host in the question is in the 0 subnet, which has a broadcast address of 127 since 128 is the next subnet.
  3. c Optimized network performance
  4. d Local physical network problem between NIC and router
  5. e 32-bit value that allows the recipient of IP packets to distinguish the network ID portion of the IP address from the host ID portion of the IP address

5 Multiple choice questions

  1. The subnet is, with a broadcast of
  2. allows you to use the first and last subnet in your network design; turned this command on by default
  3. To test the local stack on your host, ping the loopback interface of
  4. the subnet is 80.0 and the broadcast address is 95.255
  5. /29 is This is a block size of 8 in the fourth octet. 0, 8, 16. The host is in the 8 subnet, broadcast is 15

5 True/False questions

  1. Variable Length Subnet Masks (VLSMs)Create many networks using subnet masks of different lengths from one network


  2. Given, How many subnets?2


  3. Variable Length Subnet Masks (VLSMs)/25 (with ip subnet-zero), /26, /27, /28, /29, /30


  4. How many valid hosts per subnet?2y - 2 where y is the number of unmasked bits (or 0's)


  5. What is the subnetwork address for a host with the IP address is a pretty simple question. A /28 is, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
