1, Define and contrast the following terms: subnet, prefix, and BGP route? (6 points) 2, Consider a datagram network using 16-bit host addresses. Suppose a router uses longest prefix matching and has the following forwarding table: Prefix Match Interface 1 11 111 Otherwise 0123 11100000 10111111 10110000 10111111 11010000 10111111 01110000 10111111 10000000 10111111 0 2 For each of the following 5 host addresses, give the matched interface # using above forwarding table. (10 points) 3, How big is the MAC address space? The IPv4 address space? The IPv6 address space? Note: The size of an address space is the maximum number of different addresses it can have. (3 points) 4, In CSMA/CD, after the 5th collision, what is the probability that a node chooses K=4? The result K=4 corresponds to a delay of how many seconds on a 100 Mbps Ethernet? (5 points) 5, List the serious security flaws of Wired Equivalent Privacy (WEP) for 802.11 wireless networks. How those security flaws are addressed by WiFi Protected Access (WPA)? (6 points) 6, Describe IPsec and how it can be used to create virtual private networks (VPNs). (6 points) 7, What is the difference between a permanent address and a care-of address? Who assigns a care-of address? (4 points) 8, Identify and describe at least three common network vulnerabilities? (6 points) 9, What is an important difference between a symmetric key system and a public key system? (5 points) 10, True or False, explain why? (4 points) a, Ethernet and 802.11 uses the same frame structure. b, The addresses in an Ethernet frame header are IP addresses. 11, Complete the Wireshark Lab: SSL. The answers to all the questions in the lab are posted in Canvas. Follow all the steps in the lab and try to answer all the questions. Then check your answers using the solution file provided. There is no need to submit your answers to me for grading. You only need to submit a screenshot to show me that you opened the trace file and did the lab. (6 points) Note: The files for the Wireshark Lab and the solutions are provided separately. Wireshark_SSL_v8.0.pdf Wireshark_SSL_SOLUTION_v8.0.pdf 12, Conduct a survey on routing protocols, select one protocol and discuss how it works, identify its advantages and disadvantages. The length of your review should be no more than 2 pages in length. Please use APA (American Psychological Association) style for in-text citations and references.(https://owl.english.purdue.edu/owl/resource/560/01/) The rubric I use for grading your review is attached for your reference.
