1. Choose all the necessary and suitable MAC address, IP address for interfaces and port addresses implied by the above description. State clearly in your submission the choices you have made for these addresses.! Do not give the addresses in binary but in the X.X.X.X decimal format for the IP addresses, the hexadecimal format for MAC addresses and decimal numbers for the port numbers.!
2. For the delivery of the message from Computer A to Computer B, for each step along the way show the source and destination!a. MAC addresses!b. IP addresses!c. Port addresses!
Making it clear which is the source and which is the destination, in what packet or frame these addresses appear (IP, TCP, Ethernet) and what the order of encapsulation is.!
3. The same as number 2, but for the reply from computer B to computer A!
4. These messages are sensitive. What security vulnerabilities and threats can you see?
What measures would you put in place to remove or minimize the vulnerabilities?!
Compute in GF (28): ( x 4+ x +1) / ( x 7+ x 6+ x 3+ x 2) , where the irreducible polynomial is the one used by AES, P ( x )= x 8+ x 4+ x 3+ x +1.
Provided that both engineering and front office areas use 10BaseT (twisted-pair Ethernet), how might you interconnect two areas?
Illustrate how many protocols and protocol implementations are required to permit all nodes to communicate?
Be sure to allow for spaces and punctuation between words. How long would it take to transmit the text over a T-1 line at 1.544Mbps and a fibre optic link at 2.488Gbps?
If you have a class B network and want to divide it into subnets, each with 126 hosts, which subnet mask should you use? What are the four addresses (broadcast and network number) for the network starting at 131.204.18?
Richard Sclove argues that we must do more to acknowledge technoogy's 'polypotency.' What does this term mean, why does Sclove think that it is significant to acknowledge this characteristic of technology?
Describe what is the biggest problem in routing security also discuss political feasibility and what factors go into determining whether something is politically feasible in an organization
What are some immediate differences in the two protocols? Does IPv6 provide operational improvement, as well as increased address space?
You are hired to design an IP addressing scheme for five departments that will give security and access to Internet. Each department requires between 1,500 - 2,000 IP addresses.
You will design a flowchart and pseudo-code for the application given below. Program will accept user input to store student's first and last name. If name is ZZZ, then the program will end.
1-Which of the following extensions point to an executable string of code?
Describe the concept of subnetting and concept of subnet masks. Why do we utilize subnetting? How do we know which bits are used to recognize network?
