Assignment Detail:- COIT20261 Network Routing and Switching - Central Queensland University PART A Question 1: To which hardware feature do the Interfaces in the Interface column in a routing table refer???? Question 2: The destination network in a classful address can be determined by examining the first four bits of the destination address- Explain how this gives the required information- Question 3: Assume that in an IPv4 packet, there were 16 bytes of Options- What is the value of the Header Length field -HLEN-???? Explain your answer or show your calculations- Calculations or explanation: Question 4: Identify three main differences between classless addressing and classful addressing???? Question 5: In the transition period toward full adoption of IPv6 a transitioning technique called ‘tunnelling' is used- Explain the circumstances in which tunnelling would be used and how it works- PART B Question 1: Basic block informationA company has obtained a block of IPv4 addresses from an ISP- The block included the address 191-56-125-34/23-Calculate the number of addresses in this block, the network address, the direct broadcast address, and the range of addresses that would be available for use by hosts- -4 marks for correct answers, 2 marks for good calculations- However, if no calculations are provided for any item, the maximum mark for this question will be 2 marks-- The number of addresses available in this block: The network address: The direct broadcast address: The range of addresses that can be used by hosts: calculations: Question 2 Address allocations from a block A company has been granted a block of classless addresses which starts at 198-87-16-0/22- You have been given the task of creating four subnets from this block, the boss has given you an estimate of the number of addresses they require per subnet, shown below- For your answer, create a table that the shows for each subnet, the number of addresses you allocated, the subnet address and its prefix, and the last address of each subnet- Show your calculations in the space provided-Four subnets with estimated requirement:a- 1 subnet with 400 addresses-1 mark correct subnet, +0-5 mark good calcs-b- 1 subnet with 200 addresses -1 mark correct subnet, +0-5 mark good calcs-c- 2 subnets with 100 addresses each-1 mark per correct subnet, +1 mark good calculations for both subnets- Question 3The section of the Internet in the diagram below shows six networks and four routers, labelled R1, R2, R3 and R4- Construct the routing table of router R4by completing the table provided below the diagram- List the networks in longest mask order- Question 4 TCP vs UDPThere are many differences between the TCP and UDP protocols- For example, UDP is unreliable while TCP is reliable; UDP is connectionless while TCP is connection-oriented; UDP is generally faster in throughput while TCP is slower-Identify four differences other than the ones named above and write a brief explanation of each difference you have identified- PART C Question 1 Discuss the circumstances which might lead an organisation to use subnetting or alternatively to use supernetting in managing their block allocation- Question 2In the context of ad hoc wireless routing protocols, describe how a route discovery process works- Question 3DNS is critical to the operation of today's networks- Discuss how DNS works using examples where appropriate, and why it is critical to the operation of today's networks- Use your own words, do not copy or quote large passages from lecture notes or textbook- Attachment:- Network Routing And Switching-rar
