1. If the subnet mask 255.255.255.240 is applied to each of the following IP addresses below. What subnet is the packet sent to in each one of the three scenarios)? Show your work and/or explain your answer. (Please note the appropriate answer to a "What subnet is the packet sent to?" would be the particular subnet's network address.) a. 10.20.35.96 b. 10.50.35.102 c. 192.168.12.234 2. The subnet mask 255.255.255.128 is applied to a packet with a destination IP address of 192.168.12.235. What subnet is the packet sent to? Show your work and/or explain your answer. Note: The answer will be a network address of the subnet. 3. A host computer is assigned the IP address 192.168.13.8 and a subnet mask of 255.255.255.224. The host sends a packet to another host with an IP address of 192.168.13.65. Is the destination IP address in the same subnet as 192.168.13.8? Show your work and/or explain your answer. 4. A subnet mask of 255.255.255.240 is applied to a packet with a destination of 172.16.123.213. What subnet is the packet sent to? The subnet can be answered in a form of the network address. Show your work and/or explain your answer. 5. A/27 subnet mask is applied to a packet with a destination of 172.16.123.245. What subnet is the packet sent to? The subnet can be answered in a form of the network address. Show your work and/or explain your answer. 6. A host computer with an IP address of 192.168.12.5 using a subnet mask of 255.255.255.192 and a gateway of 192.168.12.1 pings a computer with an IP address of 192.168.12.83. Will the data packet from 192.168.12.5 be sent to 1) its gateway first or 2) directly to 192.168.12.832 Show your work and/or explain your answer. 7. A host computer with an IP address of 128.123.168.12 using a subnet mask of 255.255.192.0 pings a computer with an IP address of 192.168.170.102. Will 128.123.168.12 send the data packet to 1) its gateway or 2)will it send an ARP request broadcast for 192.168.35.1022 Show your work and/or explain your answer. 8. XXX.XXX.XXX.XXX 84.102.183.22Given the following point to point (/30) network, what is the IP address of the unknown router (labeled xxx.XXX.XXX.Xxx)? Show your work and/or explain your answer. BA Bubnet 2001 Far June 1928867 128 255 256 256 Fun Fus 9. You have a subnetwork, 192.168.67.0/24. It is divided into subnet A and subnet B. Your boss wants to add a third subnet, C, with 3 hosts. Is this possible? If yes, provide the network address of the new subnet you will be adding (i.e. 192.168.2.14). If it is not possible, justify it. Show your work and/or explain your answer. 10. The following shows a network with two subnets. A device on the network is misconfigured. Select the letter of the device (i.e. A) which has an invalid IP address. Show your work and/or explain your answer. 192.186.100.000 11. You are given the address 206.206.15.6/29 by your ISP for your router's interface. You are also given 206.206.15.7 as your default gateway. Will this work? Show your work and/or explain your answer. 11. You are given the address 206.206.15.6/29 by your ISP for your router's interface. You are also given 206.206.15.7 as your default gateway. Will this work? Show your work and/or explain your answer. 12. Subnet the Address 128.20.0.0/16 into smaller subnets supporting 500 Hosts each. Show your work and/or explain your answer. a What is the New Subnet Mask b. What is the IP Address range of the first network? 13. The following CIDR blocks were recommended to be used in 4 different subnets in your network. 172.16.0.0/20 172.16.80.0/22 172.16.64.0/21 172.16.128.0/22 Are there are any problems with the recommended CIDR blocks? Review the recommendation. If there are problems, state the reason and provide a solution. Show your work and/or explain your answer. 14.
