0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
1. If the matrix size is [2x2], use your first name as an input message (Plaintext), and use the key (GLEP) to encrypt your first name. Your answer should be detailed, you should show each output of each step of the algorithm besides the final answers. (16 marks)
Note: Any empty places can be padded with redundant letters (the ‘x’ in the chosen)
2. If the matrix size used in Encryption is [3x3] and the key was (JQDSMFIBL), answer the following question
a- What will be the Inverse Matrix? Your answer should be detailed (8 marks)
b- What is the Plaintext if the Chiphertext is (ECKGYKOFRLNR) (16 marks)
Your answer should be detailed, you should show each output of each step of the algorithm besides the final answers.
NOTES
• Make sure to write your name and ID clearly.
• Answer all questions and do not exceed the word count.
• Always make citations and referencing (provide proper references using any format).
• Use your own words (copy and paste cause deduction of marks even if you provide proper references).

TMA
Summer Semester 2014-2015
Cut-off Date: 24-07-2015
Inside Reading: The Academic Word List in Context
This assignment is adapted from the Writing and Discussion Topics section on p. 16, Unit 1 “The Strength to Survive”.
Format and Word Count:
The student’s work should be:
• written in a form of an ESSAY of around 800 words (13 marks).
• presented in class in any form the student finds suitable such as PowerPoint presentation, pictorial presentation, talks and open discussion, role-play and dramatization, etc. (5 marks)
Referencing:
The essay should include a list of references (print and electronic) at the end in addition to in-text referencing as per the requirements of the MLA Referencing System. Proper referencing is a serious academic requirement and skill and will be rewarded accordingly (2 marks).
Writing and Discussion Topic:
Performing-enhancing drugs, some quite dangerous, are now a part of modern sports, and many sports heroes have been accused of using these substances.
You are required to:
1) choose a specific athlete who was accused of using performing-enhancing drugs.
2) research well what made him/her use these substances.
3) discuss the effects of these substances on his/her career and personality.
4) comment/reflect on what should happen to any athlete caught using performing-enhancing drugs.
5) provide some suggestions and recommendation to minimize the occurrence of this phenomenon.
6) present your work in-class.
Guidance on Addressing the Topic:
Before you embark on writing the essay, you need to read carefully Unit 1 “The Strength to Survive” in order to familiarize yourself with the topic at large and make use of the specialized vocabulary items in your essay.
You are strongly advised to consult sources on the topic and widen your knowledge of the topic under consideration, but it is of the utmost importance to document any words or ideas that are not your own.
Once you have the material ready, it is advisable that you follow the steps (1-6) indicated in the section above to avoid omitting sub-questions. Although the topic is from Unit 1, you should demonstrate your knowledge of the reading strategies covered in other units, as well as the words covered in those units.

Note: List the new subnets with their new prefix
Question 4 (16 marks)
This question covers subnetting networks covered in chapters8 “IP addressing” & 9 “Subnetting IP network”
a. Figure A shows the design of a network that is going to be implemented.(14 marks)
The details of the topology of the network are as follows:
• Net 1 LAN “Employee LAN”: has 30 PCs and 30 VoIP phones connected to 3 Switches*.
• Net 2 LAN “Server Farm LAN”: has 10 Servers connected to 1 Switch*.
• Net 3 LAN:“Admin LAN”: has 25 PCs and 3 Network printers connected to 1 Switch*.
• Net 4 LAN “Freelance LAN”: can accommodate at the same time up to 12 Laptops and 12 wireless devices connected to 1 access point*.
• Net 5 LAN “Wireless network”: can accommodate at the same time up to 20 Smart devices connected to 1 access point*
• Net 6 WAN: router 1 “R1” is directly connected to router 4 “R4”.
• Net 7 WAN: router 1 “R1” is directly connected to router 2 “R2”.
• Net 8 WAN: router 1 “R1” is directly connected to router 3 “R3”.
* the switches and access points should be accessed remotely.
Subnet the address block 180.18.0.0/23 as appropriate to provide an efficient use of the addresses but at the same time providing sufficient addresses for all groups and links. Before you start determining the number of hosts for each network, please read the “Important Notes” section here after.
Design an addressing scheme for the company by completing a copy of Table 1.
You should complete one row for each different LAN/WAN links and use 180.18.0.0/23 as your starting address. You should use subnet 0.
Important Notes:
• An IP address should be assigned to each switch in order to be able to configure/access it remotely.
• An IP address should be assigned to the access point in order to be able to configure/access it remotely.
• Your choices should make the most economical use of the address range
• You are not expected to send in a packet tracer file or to simulate the network in any way. You just need to copy and complete Table 1
• You can change the order to the Name of the LAN/WAN in table 1
Name of LAN/WAN Network (subnet) address Address range Broadcast address Subnet mask
Net 1
Net 2
Net 3
Net 4
Net 5
Net 6
Net 7
Net 8
Table 1 to be completed
b. From the address block 180.18.0.0/23 used in part a list all the unused subnets. (2 marks)
Question 5 (17 marks)

Question 3 (19 marks)
This question allows you to demonstrate your understanding of the different number bases associated with CCNA1. In order to obtain the full mark you must provide the details. You might use a calculator to check that your answers are correct, however it will be very useful for you to be able to manipulate these numbers without the use of a calculator as the calculator Is not allowed in the Cisco final exam nor in the MTA or Final exam.

Question 4 (16 marks)
This question covers subnetting networks covered in chapters8 “IP addressing” & 9 “Subnetting IP network”
a. Figure A shows the design of a network that is going to be implemented.(14 marks)
The details of the topology of the network are as follows:
• Net 1 LAN “Employee LAN”: has 30 PCs and 30 VoIP phones connected to 3 Switches*.
• Net 2 LAN “Server Farm LAN”: has 10 Servers connected to 1 Switch*.
• Net 3 LAN:“Admin LAN”: has 25 PCs and 3 Network printers connected to 1 Switch*.
• Net 4 LAN “Freelance LAN”: can accommodate at the same time up to 12 Laptops and 12 wireless devices connected to 1 access point*.
• Net 5 LAN “Wireless network”: can accommodate at the same time up to 20 Smart devices connected to 1 access point*
• Net 6 WAN: router 1 “R1” is directly connected to router 4 “R4”.
• Net 7 WAN: router 1 “R1” is directly connected to router 2 “R2”.
• Net 8 WAN: router 1 “R1” is directly connected to router 3 “R3”.
* the switches and access points should be accessed remotely.
Subnet the address block 180.18.0.0/23 as appropriate to provide an efficient use of the addresses but at the same time providing sufficient addresses for all groups and links. Before you start determining the number of hosts for each network, please read the “Important Notes” section here after.
Design an addressing scheme for the company by completing a copy of Table 1.
You should complete one row for each different LAN/WAN links and use 180.18.0.0/23 as your starting address. You should use subnet 0.
Important Notes:
• An IP address should be assigned to each switch in order to be able to configure/access it remotely.
• An IP address should be assigned to the access point in order to be able to configure/access it remotely.
• Your choices should make the most economical use of the address range
• You are not expected to send in a packet tracer file or to simulate the network in any way. You just need to copy and complete Table 1
• You can change the order to the Name of the LAN/WAN in table 1
Name of LAN/WAN Network (subnet) address Address range Broadcast address Subnet mask
Net 1
Net 2
Net 3
Net 4
Net 5
Net 6
Net 7
Net 8
Table 1 to be completed
b. From the address block 180.18.0.0/23 used in part a list all the unused subnets. (2 marks)
Question 5 (17 marks)
This question allows you to demonstrate your ability to program a network of Cisco switches using packet tracer. The Packet tracer file for this question is T216AFA15TMA01Q5.pkt will be found on the AOULMS (Moodle).
