Network+ Guide to Networks, 5 th Edition Solutions 10– 1 Network+ Guide to Networks, 5 th Edition Chapter 10 Solutions Review Questions 1. Convert the following subnet mask into its dotted-decimal equivalent: 11111111 11111111 11111000 00000000. a. 255.255.248.0 2. What is the default subnet mask for a Class A network? d. 255.0.0.0 3. A node on a network has an IP address of 140.133.28.72 and its subnet mask is 255.248.0.0. What type of subnetting has been used on this network? c. Supernetting 4. On a network with an IP address of 140.133.28.72 (or 10001100 10000101 00011100 01001000) and a subnet mask of 255.248.0.0 (or 11111111 11111000 00000000 00000000), what is the network ID? c. 140.248.0.0 (or 10001100 11111000 00000000 00000000) 5. As a networking consultant, you've been asked to help expand a client's TCP/IP network. The network administrator tells you that the network ID is subnetted as 185.27.54.0/26. On this network, how many bits of each IP address are devoted to host information? b. 6 6. If you worked on an older network that could not interpret classless addressing, and your network ID was 145.27.0.0, what is the theoretical maximum number of different subnets you could create on this network? d. 254 7. You have decided to create 254 subnets on your Class B network. What subnet mask will you use to accomplish this? a. 255.255.255.0 8. If you subdivide your Class B network into 254 subnets, what is the maximum number of hosts you can assign to any single subnet? b. 254 9. Your company has leased a Class C network whose network ID is 205.61.128.0. You want to create 16 subnets within this network. One of the subnets will have an extended network prefix of 205.61.128.64. What will be the broadcast address for this subnet? ( Hint : If you know the number of hosts per subnet, you can easily determine the broadcast address.) d. 205.61.128.79
