  1. Give me the subnet, addresses for the first valid hosts and last valid hosts and the broadcast addresses for the following subnet masks

    2. 172.16.10.5/25

    172.16.10.33/27

    172.16.10.65/26

    172.16.10.17/30

    172.16.10.33/28

    192.168.100.25/30

    192.168.100.37/29

    192.168.100.66/27

    192.168.100.17/29

    10.10.10.5/20


  2. You need 500 subnets each with about 100 usable host addresses per subnet. What mask will you assign using a class B network?



  3. You need to configure a server that is on the subnet 192.168.19.24/29. The router has the first available host address. What Address and Subnet will you assign to the server?



  4. What are VLSMs and what are they used for?



  5. Why would you use a different subnet for your Point to Point WAN connections?



  6. When would you use a /30 subnet?



  7. What are block sizes? why are they useful to know?



  8. On page 140 there is a cool little diagram question at the top. Please fill in the blanks with the corresponding correct addresses/masks from the right side of the diagram.



  9. What does Summarization/route aggregation do?



  10. What is the block size of: 192.168.16.0 through network 192.168.31.0



  11. What is the network address used to advertise summary address?



  12. What mask is used to get a block size of 16?



  13. What is the block size of: 172.16.32.0 through network 172.16.50.0



  14. Of the 2 block sizes that would work which is the better of the two and why?



  15. What are the 4 troubleshooting steps Cisco Reccomends for troubleshooting IP addresses? If these steps don't work what is the problem?



  16. If we were to change each of the switches in here to managed cisco switches, and assign a different subnet to each. Please choose the subnetmask scheme and ip address scheme for the room and then draw it out in a comprehensive network diagram. also write a small paragraph defending why you chose the scheme you did.
