Scenarios

     

The following scenarios and questions are designed to draw together the content of the chapter and exercise your understanding of the concepts. There is not necessarily a right answer. The thought process and practice in manipulating the concepts is the goal of this section. The answers to the scenario questions are found at the end of this chapter.

Scenario 2-1

A network has a remarkably even distribution of campuses, buildings, and hosts . The company has four campuses, each campus has four buildings , each building has five floors, and each floor has approximately 100 hosts. Each building also has a basement where the building servers are held.

There are eight locations distributed globally. Each location replicates this physical design. The locations are connected via dedicated leased T1 lines. Each T1 constitutes a subnet.

1:

Draw the topology map for one of the locations.

2:

Using the network address 10.0.0.0, design an addressing scheme that can be summarized. Apply the binary notation for the bit allocation to your diagram.

3:

List the range of hosts on one of the subnets allocated to a floor in a building.

4:

Indicate how summarization would work within the location.

5:

Allocate a subnet to be used for VLSM to address the WAN links between the locations.

6:

Is it possible to summarize the WAN subnets?


Scenario 2-2

Study Figure 2-12, and answer the questions that follow.

1:

To address this network, what class of address would you apply to the Internet?

2:

Could you use VLSM? Give reasons for your answer.

3:

If you could use VLSM, write out the masks that you would deploy in binary notation.

4:

Could summarization be implemented?
