Title: Final Exam
Course: KVCC CPT128 > Section: Assessments

Question #1

One of the very first topics that we discussed in class is that of the OSI model and how it relates to the field of networking. You have answered similar questions before however as we have gone into further detail and illustrated these categories further this can be readdressed.

a.      First of all, you want to choose the model that is used in the book which consists of five layers that of the Physical, Link, Network, Transport, and Application. Once these are identified you want to go into an in-depth examination of these levels bringing up the topics discussed in class.

b.      What does the layer do and what components and functions are a part of it?

c.      As part of this discussion you should relate each part of the model to your personal or professional life. How could you apply the concepts of each to your lives?

d.      Once your examination is done I want you to describe why you think this is important.

i.     Why do you think we spent so much time going over the OSI model?

ii.     What benefits do you get by studying and knowing networks at a very deep level?

iii.     How can you take this knowledge into the future?

Question #2

In class we have discussed various mediums (i.e. Fiber Optics, Twisted Pair, etc.) that can be used as part of the physical layer. Each of these media categories has its purposes and most are still used today in various situations. The book groups these mediums into three categories guided, wireless, and satellite. For practical purposes we will group wireless and satellite into one group that of wireless. Please review all of the options that were presented in chapter two and then select one of the guided and wireless options that you believe to be the future of each medium. We have already explored many of these options in assignment three so you can include this information if you so choose. Once you have selected your two options you want to define how they function and then make the argument as to how they are the best future option, the goal is to build a persuasive argument as to why each is the future. Pretend to be a sales person and are attempting to sell me a business owner as to going with those mediums. With this goal in mind it is less focused on the technical merits but more on its future worthiness and the benefits to a business. You should examine the content in the book but should also do some outside research as well, to ultimately ensure you are making an educated decision.  Any outside sources should be included in your answer. There is no official format for citing these sources with simple web links being acceptable.

Question #3

In the field of Networking one of the most important concepts is that of media access control. First you should establish a technical definition of what this means in terms of the field of networking. Once you have created your definition you will choose two of the options for channel allocation and then break them down into detail. Explain exactly how that system works and then conduct some outside research as to how it functions and its efficiency and use. Once this examination is done you are to place some thought and develop a channel allocation method of your own. There is no expectation to have a vast technical breakdown however it is desirable that you are able to understand the idea of media access control and the concepts and use these to develop the framework of your suggestion. Use your imagination here and attempt to be as creative as possible.

Question #4

In the world of the Internet the concept of routing has become necessary to both understand and exist in the infrastructure. To apply the areas of routing you will build a sample network centered on the following scenario. You are a small ISP that will service a local town in Maine. The plan is to service the town with 10 routers in total and the connection to the Internet is not part of this question. Questions that you should answer:

e.      Will your routing system be connection or connectionless oriented?

f.       What routing algorithms will you use

i.     You should develop the routing tables in this scenario for each of the routers with ten in total.

g.      What style of casting will you use?

h.      What will you use to avoid congestion?

i.        What QOS services will you provide

j.        Once you plan everything out I want you to conduct some online research and actually select a router that you would recommend to purchase for this purpose. You should ensure that the selected router will accomplish the needs of the scenario. You can cut and past the information or provide a link. As part of this describe why you made that selection.

k.      Develop a routing diagram – see example

l.        Create a routing table for the first four routers A, B, C, D. Again see example

You should go into extended detail on these questions and defend your selection on each. When you are complete you should summarize your network and how the routing will work throughout.

Question #5

You are tasked with developing the IP addressing scheme for the new business expansion. At this location there is an expectation that you will have 1000 hosts on the network. You need to develop a scheme that supports at least twice this number so that expansion can be addressed if necessary. In this business there are three separations that should be made which are the marketing, sales, and accounting departments and each should not be able to access the other over the network. Additional things you should address:

m.    What is your address ranges?

n.      What class does it fall under?

o.      What is the network id?

p.      What is the host id?

q.      What subnets are you using?

You are to back up each of these options by conducting research and using resources that are available in the book or online. Once this is done you are to use the same scenario but instead use IPV6 addresses. How does the version change your approach to this scenario? For each you want to go through and describe why you made the decisions you did describing the purposes behind each.
