ccna study.11.Which of the following features is not required for a routing protocol to support route summarization? A.Include subnet masks in routing updatesB. Make routing decisions based on the entire destination IP address C. Summarize the last few identical routing entries D. None of the above answers are true12.For the following two routes: 192.168.1.64/27 and 192.168.1.96/27, what is the most specific summary route covering these two subnets? 13. For the following four routes: 192.168.1.32/30, 192.168.1.36/30, 192.168.1.40/30, and 192.168.1.44/30, what is the most specific summary route that covers these four subnets?7.6 Answers to Self-Test Questions1. aoRIPv2 supports VLSM (but RIPvl does not). b is a classification protocol and does not support VLSM. c contains a classification protocol. a is the correct answer, so d is incorrect.2. Bo requires two subnet masks: 255.255.255.128 (/25) and 255.255.255.192 (/26). This will create three subnets, such as 192.168.1.0/25> 192.168.128/26 and 192.168.1.192/26o Therefore, answers A, C, and D are incorrect.3. none of Do's first three answers are correct because this need cannot be met using a Class C network. Why? Because a segment containing 120 hosts requires a subnet mask of 255.255.255.128, which would occupy half of the addresses of a Class C network; a segment containing 60 hosts requires a subnet mask of 255.255.255.192, and three such segments would occupy three-quarters of the addresses of a Class C network. A is incorrect because it can only accommodate segments containing 120 hosts and two segments containing 60 hosts; B is incorrect because it can only provide two subnets; and C is incorrect because it can only accommodate three segments containing 60 hosts, but not segments containing 120 hosts.4. A andC. A creates three subnets, one of which contains 126 host addresses and the other two contain 62 host addresses; C creates five subnets, three of which contain 62 host addresses and the other two contain 30 host addresses. b is incorrect because the second subnet mask supports only 14 hosts; and d is incorrect because both A and C are the correct answers.5. Do's first three answers are incorrect. To support 64 hosts, you need to use subnet mask /25, but the subnet mask used for the address space allocated to you is /25. If the number of hosts to support is 62, you can use subnet mask /26. A, B, and C do not provide enough addresses.
